Hi Friend,

Interface: Through interface we get the multiple inheritance in java.And we implement interfaces to override the abstract methods it contains.

Abstract class: We also use abstract classes to override the abstract methods that it contains.Otherwise the child class will mentioned as abstract.

If we wants to prevent a class from instantiation then we mentioned it as abstract.

Thanks
