interface:-
an Interface is a pure abstract class, the methods in an interface are by default abstract,and the variable are final variable i.e constants,we can implement any no of interface abstract class : abstract class can have abstract methods as well as non abstract methods |

The basic difference between java abstract class and interface is that the methods of java interface are utterly abstract which don’t have implementations. Java abstract contains the instance methods which implements a default behavior.
