Inheritance



For Method Overriding (so runtime polymorphism can be achieved).
  • For Code Reusability.

    Syntax :-
    class Subclass-name extends Superclass-name                                         {                                                                                                                                //methods and fields                                                                                                                                    }
    –> The extends keyword indicates that you are making a new class that derives from an existing class. The meaning of “extends” is to increase the functionality.

    –> In the terminology of Java, a class which is inherited is called parent or super class and the new class is called child or subclass.
    Type of Inheritance :-types of inheritance in java
  • multiple inheritance in java
