In Java, when we implement an interface method, it must be declared as :
Public
All methods declared in a Java interface are implicitly public and abstract.
An overriding method cannot reduce visibility, so the implementing class must declare the method public.
Declaring it private or protected is a compile-time error, and friend is a C++ keyword that does not exist in Java.
So the method must be public.
Hence, Public.
