Since this is a Java question, I'll move this there.

Are you familiar with relational databases? I think a relational database table is a good description of a Map. It relates an identifying key (in a database table, this is called the Primary Key) to a Value (or the entity being modeled). So with a Map, it is generic with Map<Key, Value> types. The Map interface, like a database table, cannot have duplicate keys but it can have duplicate values.

We don't have any Map tutorials, but we do have some Map snippets linked to in the Java Data Structures Resource Thread.
