The picture given alongside displays a simple representation of inheritance in Java. Here, the class Parent contains an integer variable a and is a super-class to class Child which contains an integer variable b Let us see the representation of this picture by means of a code example. 1 2 ...
A hybrid inheritance is a combination of more than one types of inheritance. For example when class A and B extends class C & another class D extends class A then this is a hybrid inheritance, because it is a combination of single and hierarchical inheri
