My question is if all membars of an interface are by default static final then explicitly defining them in the declaration will make any difference?

Every field declaration in the body of an interface is implicitly public, static and final. It makes no difference whether or not you use these modifiers in your declaration.

In a similar way, every interface method is implicitly public and abstract, so the following are all identical:

void go();
public void go(); // not recommended
abstract void go();
public abstract void go(); // not recommended
