HashMap

[raghuram bikkani]

How can u implement HashMap if u don't have a HashMap?

[Bear Bibeault]

HashMap is not an interface, so you cannot implement it. Do you mean java.util.Map?

[Layne Lund]

I don't understand your question. HashMap is a concrete class, so you can create objects from it:

Map m = hew HashMap();

Does this help?

I guess that he wants to mimic the behavious of HashMap.
By 'implement' he means 'create'.

What do you mean? If you have a REALLY OLD version of Java that doesn't have HashMap, you can use java.util.Hashtable.
