The extends keyword indicates that MySubclass is a subclass of MySuperclass. ![]() In this example, MySubclass is the name of the subclass, and MySuperclass is the name of the Superclass that MySubclass is inheriting from. Here is the basic syntax for using the extends keyword in Java: public class MySubclass extends MySuperclass In Java, the extends keyword is used to create a derived class that inherits the properties and methods from its base. In addition to inheriting properties and methods from the Superclass, a subclass can also add its own methods and fields, providing additional functionality that is specific to the sub class.īy creating subclasses, developers can build on top of existing code and create new classes that are specialized for specific tasks, without having to rewrite code that already exists in the super or the base class. To inherit a child class from its parent, you should specify the extends keyword, followed by the name of any base or Superclass from which it derives. The extends keyword in Java allows a subclass to inherit the public and protected properties and methods from its base or Superclass. In object-oriented programming, a subclass, also known as a derived class or child class, is a class that derives the properties and methods from a parent class, called a base or a Superclass, as discussed above. In Java, the Object class is the ultimate Superclass of all classes, since all classes in Java inherit from it, either directly or indirectly. This is because changes made to the Superclass are automatically propagated to its subclasses. In object-oriented programming, a Superclass, also known as a parent class or base class, is a class that contains common properties and methods that are shared by its subclasses.Ī Superclass can be thought of as a generalization of its subclasses, providing a common interface and behavior that can be shared among multiple classes. In addition to inheriting the non-private members of the base, the derived class can also add its own members or override the inherited members of the base class by providing its own implementation. It facilitates code reuse, reduces code redundancy, and makes it easier to organize and maintain your code over time. Inheritance is a key feature of object-oriented programming and is used extensively in the development of complex software systems. You can learn more about object oriented programming in Java from the following tutorial: Classes and Objects in Java. This programming tutorial will discuss inheritance, its benefits, and how it can be implemented in Java. It is a concept of object oriented programming (OOP) and is a prominent feature of the Java programming language. Inheritance is a mechanism by which a class can acquire the properties and behavior (represented by methods and fields/properties) of another class. ![]() We may make money when you click on links to our partners. content and product recommendations are editorially independent.
