This is Web Archive File and used to store XML, java classes, and JavaServer pages. Heavy weight components depend on the local windowing toolkit. This intermediate language is then converted into the machine code by the Just-In-Time (JIT) compiler. If you need to support random access, without inserting or removing elements from any place other than the end, then ArrayList should be used. Method Overloadingis the common way of implementing polymorphism. To read more, refer to the article: Sealed Classes in C#. As opposed to checked exceptions, runtime exceptions are ignored at the time of compliation. 14. setBounds() method is used for this purpose. A structure is a collection of variables of different data types under a single unit. IndexOutOfRangeException: When an array index is out-of-bounds, it exception occurred. It is used to specify the name of the applet class. What is the difference between to dispose and finalize methods in C#? It attaches one, more power to the C# or .NET languages to generate a query for any LINQ compatible data source. The life cycle of a thread include . It is used to implement the core identity of class. The byteorder argument determines the byte order used to represent the integer, and defaults to "big".If byteorder is "big", the most significant byte is at the beginning of the byte array.If byteorder is "little", the most significant byte is at the end of the byte array. Java provides access modifiers to set access levels for classes, variables, methods and constructors. By doing this, we are reusing the fields and methods of the existing class. It is the casting from a general to a more specific type, i.e. If you try to add elements greater than eight, then the compiler will throw an error. List down the commonly used types of exceptions? A thread is in the ready state as initial state after it has been created and started. To read more, refer to the article: Multithreading in C#. It is also possible for programs to create objects that are not subject to garbage collection. It was introduced in .NET Framework 4.0. Inheritance is an important pillar of OOP(Object Oriented Programming). Java uses Just-In-Time compiler to enable high performance. C language can be executed cross-platform. It uses pre-defined methods which are get and set methods which help to access and modify the properties. Other examples include natural enumerated types (like the planets, days of the week, colors, directions, etc.). Exception's subclasses have to be caught first. The basic idea behind using Generic is to allow type (Integer, String, etc, and user-defined types) to be a parameter to methods, classes, and interfaces. void it affirns the compiler that no value is returned by main(). The .NET Framework class library contains many new generic collection classes in System.Collections.Generic namespace. What is the difference between a struct and a class in C#? These variables are instantiated when the class is loaded. It also provides memory allocation, type safety, etc to the code. It is mainly used to assign the names or string values to integral constants, which make a program easy to read and maintain. It can contain different types of access modifiers like public, private, protected, etc. To read more, refer to the article: Generics in C# 32. To read more, refer to the article: Managed and Unmanaged code. Implicit C++ Type Casting. It helps to reduce the complexity and also improves the maintainability of the system. And if the starting catch block is not suitable for the exception type, then the compiler searches for the next catch block. This keyword is also useful to split the functionality of methods, interfaces, or structure into multiple files. The repaint() method is used to cause paint() to be invoked by the AWT painting thread. It helps the user to point more than one method in a single call. The term File Handling refers to the various operations like creating the file, reading from the file, writing to the file, appending the file, etc. You can convert the values from one type to another explicitly using the cast operator as follows (type_name) expression The Locale class is used to tailor program output to the conventions of a particular geographic, political, or cultural region. An enumeration is an interface containing methods for accessing the underlying data structure from which the enumeration is obtained. Yes an Interface can inherit another Interface, for that matter an Interface can extend more than one Interface. Access Modifiers are keywords that define the accessibility of a member, class, or datatype in a program. Whats the difference between the System.Array.CopyTo() and System.Array.Clone() ? This process is also called type casting and it is user-defined. In computer science, a pointer is an object in many programming languages that stores a memory address.This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware.A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer. You can also use LINQ with SQL, with XML files, with ADO.NET, with web services, and with any other database. A static method should not refer to instance variables without creating an instance and cannot use "this" operator to refer the instance. A class can be sealed by using the sealed keyword. By using C language we can achieve a low level of abstraction. static it allows main() to be called without instantiating a particular instance of a class. It is possible for programs to use up memory resources faster than they are garbage collected. It helps you in code reuse, performance, and type safety. No, a top level class can not be private or protected. Unicode requires 16 bits and ASCII require 7 bits. The String class is considered as immutable, so that once it is created a String object cannot be changed. 29. In C#, You can use more than one catch block with the try block. Enumeration is declared using the enumkeyword directly inside a namespace, class, or structure. A child object constructor always first needs to construct its parent. Its general form is shown here: Here, expris an expression that describes an object whose type is being tested against type. No, it's not possible to accessed outside it's package. An Interface can only declare constants and instance methods, but cannot implement default behavior and all methods are implicitly abstract. There is no chance for you to annotate a Java class with a meta-annotation and hope it will do the same as in Groovy. When the event occurs, all registered handlers are called. Overloaded methods are differentiated based on the number and type of the parameters passed as arguments to the methods. Efficient socket based programming can be easily implemented for general communications. It is a collection returned by the values() method of the Map Interface, It contains all the objects present as values in the map. It provides the minimum requirements for executing a Java application; JAR files is Java Archive fles and it aggregates many files into one. java.util.regex consists of three classes Pattern class, Matcher class and PatternSyntaxException class. 37. Automatic memory management is made possible by Garbage Collection in .NET Framework. length - a number of the field length, as given by the database. With this Encapsulation gives maintainability, flexibility and extensibility to our code. The following is the syntax of a sealed class : A method can also be sealed, and in that case, the method cannot be overridden. The Frame class extends Window to define a main application window that can have a menu bar. To read more, refer to the article: Common Language Runtime. The Clone() technique returns a new array object containing every one of the components in the first array. The beauty of LINQ is it provides the ability to .NET languages(like C#, VB.NET, etc.) Compile the source into a code or AST object. A thread could stop waiting earlier if it receives the notify() or notifyAll() call. Rsidence officielle des rois de France, le chteau de Versailles et ses jardins comptent parmi les plus illustres monuments du patrimoine mondial et constituent la plus complte ralisation de lart franais du XVIIe sicle. type - a string of the field type in all caps. A panel provides space in which an application can attach any other component, including other panels. To overcome such types of problems Microsoft developed LINQ. The variable will be declared and initialized within the method and it will be destroyed when the method has completed. Creating Datasets. This readonly keyword shows that you can assign the variable only when you declare a variable or in a constructor of the same class in which it is declared. Postfix operators i.e () [] . It is a simple drawing surface which are used for painting images or to perform other graphical operations. Holding the reference of the other class within some other class is known as composition. In this method, Python need user involvement to convert the variable data type into certain data type in order to the operation required. Both the client-side and server-side have to provide mechanisms to make the data useful in any way. 39. Describe Accessibility Modifiers in C#? Whereas .NET Frameworkis required to execute C# language. Can multiple catch blocks be executed? You want to write a runtime exception, you need to extend the RuntimeException class. It will throw a compile-time error. The main difference between both methods is that Dispose() method is used to release the unmanaged resources of an object while Finalize is also used for the same purpose but it doesnt guarantee the garbage collection of an object. 26. VEX programs are written for a specific context.For example, a shader that controls the surface color of an object is written for the surface context. The method wait() is defined in the class Object and the method sleep() is defined in the class Thread. Type Casting in Java is nothing but converting a primitive or interface or class in Java into other type. Data Structures & Algorithms- Self Paced Course, Top 50 ASP.NET Interview Questions and Answers, C# | Get object at the top of the Stack - Peek operation, C# | Insert an object at the top of the Stack - Push Operation, Removing the object from the top of the Stack in C#, Top 10 Programming Languages for Blockchain Development, Microsoft Interview experience for full time position of software engineer at Microsoft Ireland Research, Encrypt and Decrypt Using Rijndael Key in C#. Variables, methods and constructors which are declared protected in a superclass can be accessed only by the subclasses in other package or any class within the package of the protected members' class. An Exception handling is additionally important because C# defines standard exceptions for common program errors, like divide-by-zero or index-out-of-range. Order of precedence determines the order in which operators are evaluated in expressions. Deletion in linked list is fast because it involves only updating the next pointer in the node before the deleted node and updating the previous pointer in the node after the deleted node. It has found lasting use in operating systems, device drivers, protocol stacks, though decreasingly for Basically, it converts a Value Type to a Reference Type, and vice versa. In simple words, it is a type that represents references to methods with a particular parameter list and return type and then calls the method in a program for execution when it is needed. The size is the number of elements actually stored in the vector, while capacity is the maximum number of elements it can store at a given instance of time. The Class class is used to obtain information about an object's design and java.lang.Class class instance represent classes, interfaces in a running Java application. While both encoders and standard serialization are responsible for turning an object into bytes, encoders are code generated dynamically and use a format that allows Spark to Garbage collection will always work on Managed Heap, and internally it has an Engine which is known as the Optimization Engine. e.g. In this pattern, a class has just one instance in the program that gives global access to it. All components in Swing, except JApplet, JDialog, JFrame and JWindow are lightweight components. atof(): This function is used for converting the string data type into a float data type. If you are fresher then interviewer does not expect you will answer very complex questions, rather you have to make your basics concepts very strong. It was developed by Microsoft with the .NET initiative. If a subclass provides a specific implementation of a method that is already provided by its parent class, it is known as Method Overriding. It is generally used when a method returns multiple values. Generally, multiple catch block is used to handle different types of exceptions means each catch block is used to handle different type of exception. String args[ ] args parameter is an instance array of class String. The LLVM code representation is designed to be used in three different forms: as an in-memory compiler IR, as an on-disk bitcode representation (suitable for fast loading by a Just-In-Time compiler), and as a human readable assembly language representation. 40. In this process, an overridden method is called through the reference variable of a superclass. Many web browsers, such as Internet Explorer 9, include a download manager. A continue statement is used to end the current loop iteration and return control to the loop statement. Hook hookhook:jsv8jseval Java runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX/Linux like HP-Unix, Sun Solaris, Redhat Linux, Ubuntu, CentOS, etc. These are classes that allow primitive types to be accessed as objects. Java and C++ are two prominent object-oriented programming languages.By many language popularity metrics, the two languages have dominated object-oriented and high-performance software development for much of the 21st century, and are often directly compared and contrasted.Java appeared about 10 years later and its syntax was based on C/C++ The compiler does not consider the return type while differentiating the overloaded method. These are frequently asked interview questions in C# interviews and designed for freshers. Use StringBuilder whenever possible because it is faster than StringBuffer. To read more, refer to the article: Partial classes in C#. In late binding, the compiler does not know about what kind of object it is and what are the methods or properties it holds, here the objects are dynamic objects. Java provides these modifiers for providing functionalities other than Access Modifiers, synchronized used to indicate that a method can be accessed by only one thread at a time. The primary advantage of exception handling is that it automates much of the error handling code. By default, this collection sort the key/value pairs in ascending order. When a class object is created at runtime, certain memory space is allocated to it in the heap memory. Tuples are generally used when you want to create a data structure that contains objects with their properties and you dont want to create a separate type for that. It is used with variables or methods and used to call constructer of same class. Method overriding provides the specific implementation of the method that is already provided by its super class parameter must be different in case of overloading, parameter must be same in case of overriding. Singleton design pattern in C# is a common design pattern. It also helps in the management of code, as code that targets the runtime is known as the Managed Code, and code that doesnt target to runtime is known as Unmanaged code. The out is a keyword in C# which is used for passing the arguments to methods as a reference type. Private and parameterizes single constructor, Static variable to hold a reference to the single made example. It only contains public access modifier because everything in the interface is public. If the system has low physical memory, then garbage collection is necessary. For example, we have a class and this call contains two different methods, now using multithreading each method is executed by a separate thread. Some is a struct and has implicit conversion operators that convert a type of T to a type of Some. C# Type System contains three data types: Value Types (int, char, etc), Reference Types (object),and Pointer Types. Implicit Type-Casting in Assignment. This method is used to get the primitive data type of a certain String. 12. Encapsulation and hiding of information can also be achieved using properties. What is the difference between late binding and early binding in C#? Default value of float and double datatype in different as compared to C/C++. When a class is defined within a scope of another class, then it becomes inner class. The type of the object is decided on the basis of the data it holds on the right-hand side during run-time. Exceptions are caught by handlers positioned along the thread's method invocation stack. There is also an implicit cast operator from Some to Option. The Collections API is a set of classes and interfaces that support operations on collections of objects. It is done by cast operator. If there is a necessity to make alot of modifications to Strings of characters then StringBuffer should be used. How to implement a singleton design pattern in C#? As per my experience, good interviewers hardly planned to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further discussion and what you answer . Associatity determines whether an expression is evaluated left-to-right or right-to-left. Socket based communications allows only to send packets of raw data between applications. And also maximizing the utilization of the CPU because multithreading works on time-sharing concept mean each thread takes its own time for execution and does not affect the execution of another thread, this time interval is given by the operating system. It allows the instances of a class to be indexed in the same way as an array. To read more, refer to the article: C# indexers. It refers to writing programs that execute across multiple devices (computers), in which the devices are all connected to each other using a network. Whereas C# supports object-oriented programming. For example, a string GeeksForGeeks occupies memory in the heap, now, changing the initial string GeeksForGeeks to GFG will create a new string object on the memory heap instead of modifying the initial string at the same memory location. A shader that determines the illuminance from a light is written for the light context. Since String is immutable it can safely be shared between many threads ,which is considered very important for multithreaded programming. Password requirements: 6 to 30 characters long; ASCII characters only (characters found on a standard US keyboard); must contain at least 4 different symbols; An applet can be a fully functional Java application because it has the entire Java API at its disposal. The language is proposed to be a simple, modern, general-purpose, object-oriented programming language. It improves the runtime performance of computer programs based on bytecode. Does C# support multiple inheritance? Explanation: In the above C program, the expression (double) converts variable a from type int to type double before the operation. get accessorsand set accessors. The Value type is always stored in Stack. It initializes the applet and is the first method to be called. We can implement the virtual method in the base class and derived class. What is a multicasting delegate in C#? C# can distinguish the methods with different method signatures. A class consist of Local variable, instance variables and class variables. The Java runtime system generates RuntimeException and Error exceptions. Types of Casting in Python. It is not necessary that each try block must be followed by a catch block. A String object is immutable, i.e. Java is a high-level programming language originally developed by Sun Microsystems and released in 1995. We can call an overloaded constructor from another constructor using this keyword but the constructor must belong to the same class because this keyword is pointing to the members of the same class in which this is used. The out parameter does not pass the property. The underbanked represented 14% of U.S. households, or 18. Variables used in a switch statement can only be a string, enum, byte, short, int, or char. These methods give you a control over the serialization mechanism. C# is a modern, object-oriented, and general-purpose programming language. SortedDictionary a generic collection that is used to store the key/value pairs in the sorted form and the sorting is done on the key. Python has two types of type conversion: Below are the major differences, To read more about this, please refer to C# Array vs ArrayList. Delegates in C# are similar to the function pointer in C/C++. It is used to implement the peripheral abilities of the class. Throw is used to trigger an exception where as throws is used in declaration of exception. To read more, refer to the article: ref and out keywords. If the array is an array of primitive types, then all the elements of the array will be initialized to the default value corresponding to that primitive type. Most programming languages are text-based formal languages, but they may also be graphical.They are a kind of computer language.. It also inherits all the default modifier methods and their implementation. A thread can enter the waiting state by invoking its sleep() method, by blocking on IO, by unsuccessfully attempting to acquire an object's lock, or by invoking an object's wait() method. Thus, if the result is true, expris a form of type. Runtime polymorphism or dynamic method dispatch is a process in which a call to an overridden method is resolved at runtime rather than at compile-time. It allows sequential access to all the elements stored in the collection. Read-Only Properties:When property contains only the get method. To read more, refer to the article: Inheritance in C#. STRING and BYTES are separate types that cannot be used interchangeably. Type casting are of two types they are To read more, refer to the article: Jagged Array in C#. The asthe operator can be used to perform only reference, boxing, unboxing, or identity conversions. If the GC.Collect method is called, then garbage collection occurs. Following a bumpy launch week that saw frequent server trouble and bloated player queues, Blizzard has announced that over 25 million Overwatch 2 players have logged on in its first 10 days. Another major difference is that dispose() method is explicitly invoked by the user and finalize() method is invoked by the garbage collector, just before the object is destroyed. So tuple is a data structure that gives you the easiest way to represent a data set that has multiple values that may/may not be related to each other. Explicit C++ type Casting: The word explicit means open or clear. Here each thread performs different activities. acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Full Stack Development with React & Node JS (Live), Fundamentals of Java Collection Framework, Full Stack Development with React & Node JS(Live), GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Difference between Abstract Class and Interface in C#, C# | How to check whether a List contains a specified element, String.Split() Method in C# with Examples, Different ways to sort an array in descending order in C#, Difference between Ref and Out keywords in C#, How to Extract filename from a given path in C#, Basic CRUD (Create, Read, Update, Delete) in ASP.NET MVC Using C# and Entity Framework, System.String and System.Text.StringBuilder in C#. JavaScript (/ d v s k r p t /), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS.As of 2022, 98% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries.All major web browsers have a dedicated JavaScript engine to execute the code on If there is a button instance called b1, you may add menu short cut by calling b1.setMnemonic('F'), so the user may be able to use Alt+F to click the button. What is the difference between Dispose() and Finalize() methods? The range of the short type is -(2^15) to 2^15 - 1. You can create generic collection classes. C# does not support multiple class inheritance. Non-static variables take on unique values with each object instance. Type casting is a way to convert a variable from one data type to another data type. InvalidCastException: A runtime cast is invalid. To read more, refer to the article: What is Just-In-Time(JIT) Compiler in .NET? C# performs two different types of bindings which are: It recognizes and checks the methods, or properties during compile time. java.net.Socket class represents the socket that both the client and server use to communicate with each other. Boxing is an implicit conversion process in which object type (supertype) is used. Sub class inherits all the public and protected methods and the implementation. Because it applies to is, one type is compatible with another if both are the equivalent of type, or if a reference, boxing, or unboxing conversion exists. The main thread is created automatically and it begins to execute immediately when a program starts. A thread may execute a synchronized method of an object only after it has acquired the object's lock. The >> operator carries the sign bit when shifting right. C# includes three keywords that support runtime type identification: is, as, and typeof. This is an implicit conversion of Java that returns a string if we concatenate any type to the string literal. Instance variables are variables within a class but outside any method. A programming language is a system of notation for writing computer programs. The argument bytes must either be a bytes-like object or an iterable producing bytes.. If the conversion succeeds, then a reference to typeis returned. Basically, late binding is achieved by using virtual methods. It is not necessary for every derived class to inherit a virtual method, but a virtual method must be created in the base class. However, after all the actions related to the object are completed in the program, the memory space allocated to it is a waste as it cannot be used. To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. The purpose of the System class is to provide access to system resources. Creating an Android App to Open a Webpage Using Implicit Intent Step 1: Create a New Project in Android Studio. The context affects which functions, statements, and global JavaScript (/ d v s k r p t /), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS.As of 2022, 98% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries.All major web browsers have a dedicated JavaScript engine to execute the code on There are two kinds of type-casting in Java: Explicit type-casting via a type-casting operator, as described above, and; Implicit type-casting performed by the compiler automatically, if there is no loss of precision. Likewise, you cannot write a meta-annotation in Java: both the meta-annotation definition and usage have to be Groovy code. If you need to frequently add and remove elements from the middle of the list and only access the list elements sequentially, then LinkedList should be used. Events work like this: An object that has an interest in an event registers an event handler for that event. It is used to sort collections and arrays of objects using the collections.sort() and java.utils. In C language, garbage collection is not. To read more, refer to the article: Early binding and Late Binding. OverflowException: An arithmetic overflow occurred. There are two types of Conversion: 1. A finally block of code always executes, whether or not an exception has occurred. It cause low network traffic. A catch block is always preceded by the try block. ArrayList can grow dynamically and provides more powerful insertion and search mechanisms than arrays. In C#, the System.IO namespace contains classes that handle input and output streams and provide information about file and directory structure. Exceptions are conditions that occur because of bad input etc. 42. The Exception class has two main subclasses : IOException class and RuntimeException Class. The asoperator offers a streamlined alternative to isin some cases. It is of both generic and non-generic types of collection. main() this method is called at the beginning of a Java program. The code for that has been given in both Java and Kotlin Programming Language for Android. An event is a notification that some action has occurred. Coming up next are the regular attributes of a singleton design. An applet is a Java program that runs in a Web browser. In this case, garbage collection is very useful as it automatically releases the memory space after it is no longer required. To read more, refer to the article: Generics in C# 32. The ref is a keyword in C# which is used for passing the arguments by a reference. It can have either "public" or no modifier. Basically, it is responsible for managing the execution of .NET programs regardless of any .NET programming language. It is an important C# feature is built upon the foundation of delegates: the event. Delegates and events are related because an event is built upon a delegate. Creating Datasets. It makes copies the components of one cluster to another existing array. The String class is immutable, so that once it is created a String object cannot be changed. 2. C (pronounced like the letter c) is a middle-level, general-purpose computer programming language.It was created in the 1970s by Dennis Ritchie, and remains very widely used and influential.By design, C's features cleanly reflect the capabilities of the targeted CPUs. The Reader/Writer class hierarchy is character-oriented, and the InputStream/OutputStream class hierarchy is byte-oriented. In this binding, the compiler already knows about what kind of object it is and what are the methods or properties it holds, here the objects are static objects. It can be fully, partially, interface or not implemented. Method overloading increases the readability of the program. In addition, using collections involves a significant performance overhead in the form of implicit and explicit type casting that is required to add or retrieve objects from a collection. compile (source, filename, mode, flags = 0, dont_inherit = False, optimize =-1) . It runs on the .NET Framework. It is designed to adapt to an evolving environment. The members of a namespace can be namespaces, interfaces, structures, and delegates. Here, we have covered the top 50 C# interview questions with their answers. Learn more, Complete Java Programming Fundamentals With Sample Projects, Get your Java dream job! The main objective of enum is to define our own data types(Enumerated Data Types). Two streams can be formed from the file one is the input stream which is used to read the file and another is the output stream is used to write in the file. Daemon thread is a low priority thread, which runs intermittently in the back ground doing the garbage collection operation for the java runtime system. If the data types are compatible, then C# does Automatic Type Conversion.If not comparable, then they need to be converted explicitly which is known as Explicit Type conversion.For example, assigning an int value to a long variable. to a Reference Type(object)is called Boxing. If the method overrides one of its superclass's methods, overridden method can be invoked through the use of the keyword super. This type of calling the overloaded constructor is also termed as Constructor Chaining. In explicit C++ type casting, the data type in which the value is to be converted is clearly specified in the program. An interface does not contain any constructors. Reflection is the process of describing the metadata of types, methods, and fields in a code. C language gives a top-notch performance. Given a point and a polygon, check if the point is inside or outside the polygon using the ray-casting algorithm.. A pseudocode can be simply: count 0 foreach side in polygon: if ray_intersects_segment(P,side) then count count + 1 if is_odd(count) then return inside else return outside Where the function ray_intersects_segment return true if the horizontal ray Dynamic binding means that the code associated with a given procedure call is not known until the time of the call at run-time. To read more, refer to the article: Multiple catch block in C#, A jagged array is an array of arrayssuch that member arrays can be of different sizes. A client program creates a socket on its end of the communication and attempts to connect that socket to a server. It is used to create objects that provide access to the files and directories of a local file system. It contains both declaration and definition parts. Jagged Array can also be mixed with multidimensional arrays. This compromises type safety and contradicts the basic definition of C# as a type-safe language. Or we can say that if any changes made in this argument in the method will reflect in that variable when the control return to the calling method. If a class has multiple functions by same name but different parameters, it is known as Method Overloading. What is the difference between Array and ArrayList?
