Redundant interface declaration
Reports interfaces in a class' implements list or an interface's extends list that are already implemented by a superclass or extended by a superinterface. Such declarations are unnecessary and may be safely removed.
Example:
class X implements One, Two {
}
interface One {}
interface Two extends One {}
After the quick-fix is applied:
class X implements Two {
}
interface One {}
interface Two extends One {}
Use the options to not report on Serializable or Externalizable in an extends or implements list.
