Description Markus Keller CLA 2006-07-11 05:37:07 EDT 
When a type implements an interface that is already implemented by one of its supertypes, then the declaration in the subtype is superfluous. The compiler could flag this as unnecessarily implemented interface.

interface I { }
class A implements I { }
class B extends A implements I { } // "implements I" is unnecessary
