mainly there is no multiple inheritance in java...
but we can make our program to work like multiple inheritance and it is possible via interface..

interface is blue print of class,it is used to achieve fully abstraction and multiple inheritance in java.

java compiler adds public and abstract keyword before the interface method and public static and final keyword before data members.you can see this via decompile the class.

an interface extends another interface.

class MyClass implements MyInterface1,MyInterface2{}
OR
class MyClass extends ParentClass implements MyInterface1{}
