Java interface

[Vijay Chandran]

Dear Friends,

While implementing an interface is it possible to give the implemented method as final in the implementing class?

interface A {
void methodA();
}

class B implements A {
    public final void methodA() { // Is this possible?
     //Implementation Code
   }
}

Because in the eclipse editor this is not giving any compiler error. If this is possible why this is allowed?

Thanks & Regards,
Vijay

Why wouldn't it be allowed?

[Vijay Chandran]

interface methods are implicitly public / abstract. So i couldn't understand the concept of allowing final in the implementation of public / abstract method.


Kindly provide me a clarification.

Thank you very much.

Vijay

They're abstract in the interface. As soon as they are implemented they are no longer abstract in the implementing class.
