What’s point of declaring an interface as abstract? Same thing for an interface method. Is there a point to it?
eg.
public abstract interface Presenter {
public abstract void go(final HasWidgets container);
}
Where did you come across the chunk of code you have posted, any old java code base ?
This is what the JLS has to say :
9.1.1.1 abstract Interfaces:
Every interface is implicitly abstract. This modifier is obsolete and should not
be used in new programs.
9.4 Abstract Method Declarations:
For compatibility with older versions of the Java platform, it is permitted but
discouraged, as a matter of style, to redundantly specify the abstract modifier
for methods declared in interfaces.
