What is Inheritance In Java ?

Inheritance is a mechanism that allow to copy all the features(variables and methods) of super class in sub class. Inheritance exists in different forms:

1. Single Inheritance(only one super class)
2. Multiple Inheritance(Many super classes)
3. Hierarchical Inheritance(one super class and many sub classes)
4. Multilevel Inheritance(Derived from derived class)

Java supports two ways to implement Inheritance 

1. extends keyword(used with classes)
2. implement keyword(used with interfaces)

Java doesn't supports multiple Inheritance, but still this concept can be implemented using interface.
