Overriding a method with generic Map parameter

Question

I have following code:

class Key{
 --Some Implementation
}

class A{
   public void grpMap(ConcurrentMap<Key,List<Key> keyList){ 
   --Some Implementation   
   }

}

public class B extends A{
   --Edited
   @Override -- [Made "O" capital case after kocko's reply]
   public void grpMap(ConcurrentMap<Key,List<Key> keyList){ 
   --Some Implementation   
   }


}

With above code i get following error in class B

The method grpMap(ConcurrentMap) of type B must override or implement a supertype method

My problem is i can't change the way classes key, B and C are declared as these are legacy classes.

Any suggestion on how to get rid of this error?

EDIT---

JDK version used is 1.6.43 I am using eclipse which will auto generate annotations.

Its a compile time error there is no stacktrace. Error is pasted in the question. — Lokesh, Feb 17 '14 at 09:26

The annotation

@override

should be

@Override
 ↑

Also, check you Java version in the IDE - it should be 1.6, or newer, in order to get rid of the error.

Open Project properties -> Java compiler -> Set compliance level to 1.6 -> OK.

That was a typo. COrrected it. I am using eclipse, so it generates annotations on its own. – Lokesh Feb 17 '14 at 09:14
Thanks. I am using Jdk 1.6. Also i believe jdk version 1.5 to 1.6 will play a role in case of interface overriding. – Lokesh Feb 17 '14 at 09:18
I'm wondering about the class visibility. Are the classes in the same package ? – Konstantin Yovkov Feb 17 '14 at 09:38
