java interview question
when will we use abstraction or interface
View Answers

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
