Redundant generic parameters

Question

I have this two interfaces and classes:

public interface Identifiable {
    T getId();
}

public interface GenericRepository

        

Answer 1

Not much you can do, other than introduce an interface that just refines GenericRepository

  public interface LongKeyedRepository> 
        extends GenericRepository { {
  //No new methods need to be defined
  }

Then you can have

private LongKeyedRepository myEntityRepository;

etc.
