In the diagram, class D extends classes A and B. In this way, D can inherit the non-private members of both classes. But, in Java, we cannot useextendskeyword with two classes. So, how will multiple inheritance work? Till JDK 1.7, multiple inheritance was not possible in java. Butfrom...

Along withAbstraction,Encapsulation, andPolymorphism,Inheritanceforms the backbone of Object-oriented progr...
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

The above code defines a Java class named 'Main' with a 'main' method. Inside the 'main' method: An 'Animal' object named 'animal' is created. A 'Cat' object named 'cat' is created. Both 'Animal' and 'Cat' are classes defined elsewhere in the code. They have a method called '...
