For consistency's sake, we can of course keep this, but [according to the JLS](http://docs.oracle.com/javase/specs/jls/se7/html/jls-9.html#jls-9.3), they're all redundant:

"Every field declaration in the body of an interface is implicitly public, static, and final. It is permitted to redundantly specify any or all of these modifiers for such fields."
