Description
By default, the attributes declared in Java interfaces are public.
This rule, removes the public modifiers from method declarations and public static final modifiers from field declarations in interfaces.
Note, from Java 9 it is possible to have private methods in interfaces, too.
Benefits
Removes the clutter and unifies the attributes of Java interfaces.
