Java interface.

Question

Why's keywords like private and public is not use in interface method definition in java but those keywords is use in the class when implementing it.

Answer 1

Methods inside an interface in Java are implicitly public so you need not specify that. Java 8 has introduced static and default methods as well.

You cannot have a private or protected method inside an interface because then you will not be able to give implementation to it.
