![]() Here learn how to implement OOP concepts in C# and. Four key concepts of OOPs are abstraction, encapsulation, inheritance, and polymorphism. OOPs is a concept of modern programming language that allows programmers to organize entities and objects. Īn object is a basic unit of Object-Oriented Programming that represents real-life entities.This article introduces Object Oriented Programming (OOP) in C#. Body: The class body is surrounded by braces. ![]() A class can implement more than one interface. Interfaces (if any): A comma-separated list of interfaces implemented by the class, if any, preceded by the keyword implements.A class can only extend (subclass) one parent. Superclass (if any): The name of the class’s parent (superclass), if any, preceded by the keyword extends.Class name: The class name should begin with the initial letter capitalized by convention.Modifiers : A class can be public or have default access (Refer to this for details).In general, class declarations can include these components in order: This includes classes for objects occurring more than once in your code. Using classes, you can create multiple objects with the same behavior instead of writing their code multiple times. It represents the set of properties or methods that are common to all objects of one type. Message passing involves specifying the name of the object, the name of the function and the information to be sent.Ī class is a user-defined blueprint or prototype from which objects are created. A message for an object is a request for execution of a procedure and therefore will invoke a function in the receiving object that generates the desired results. Message Passing : Objects communicate with one another by sending and receiving information to each other. Method body : It is the block of code, enclosed between braces, that you need to execute to perform your intended operations.Exception list : The exceptions you expect the method to throw.If there are no parameters, you must use empty parentheses (). Parameter list : Comma-separated list of the input parameters that are defined, preceded by their data type, within the enclosed parentheses.Method Name : The rules for field names apply to method names as well, but the convention is a little different.The return type : The data type of the value returned by the method or void if it does not return a value.default (declared/defined without using any modifier): Accessible within the same class and package within which its class is defined.private: Accessible only within the class in which it is defined.protected: Accessible within the package in which it is defined and in its subclass(es) (including subclasses declared outside the package).public: Accessible in all classes in your application.In Java, there are 4 types of access specifiers: from where it can be accessed in your application. Access Modifier : Defines the access type of the method i.e.Starting off with the method declaration, it consists of six components: Let us discuss prerequisites by polishing concepts of method declaration and message passing.
