Why can't we instantiate an interface or an abstract class in java without an anonymous class method?

Question

I know, we can not instantiate either an interface or an abstract class in java except using anonymous class method but what is the reason behind it?

Answer 1

Here is a basic explanation without deeper concept.

• Interface has no method implemented, so there is no purpose to instantiate it as 'nothing' will happen when invoke a method
• Abstract class can have abstract method declaration, which is like a interface method with no implementation.
