i got a question in whizlabs mock test that can interface have static methods? i said no...it cant....but why?

is it because if we had static method in interface it would be empty....and static methods cant be inherited

are there are any other reasons too?

Reason is the purpose why Interface has been designed.
Interface can just say what to do not how to do.
So it can only declare any method (what to do), cannot give body(how to do) to them.
There is no declaration for static methods, as static methods are class methods, not instance methods.

Every method declaration in the body of an interface is implicitly abstract and static methods cannot be abstract.
