Thanks for all your replies.

I have done this

public class MultipleValueHashMap<T, U>  implements Map<T, java.util.List<U>> {

I want to implement Map rather than extend HashMap as per Josh Bloch's Effective Java item 16. http://java.sun.com/docs/books/effective/toc.html

So I do not want to do this.
public class MM2<T,U> extends HashMap<T, List<U>>  {
}

Thanks for all your help. I will look into some of the other answers later in the week.

Many thanks
Richard
