this is what you are looking for:

the java API....

search for the Collection/Map interfaces (located in the java.util package) and then checkout the "All Known Implementing Classes" section...

there you can find implementations (abstract and concrete) of the interfaces.

I just found great collections complete overview table.

This table helped me again to solve old classical Java question hashtable vs hashmap :-)

I hope it helps you
