i am new to java and at presently am getting the intial touch of java.I have read about collections and have some fundamental knowledge about it.
Now my question is that when to use hashmap and when to use hashtable,Sortlist or Array list.Can any one clarify me more about the collections.What are the other topics (or java packages) that i should focus in order to get a fast and quick grip on programming.
Thanks a lot guys in advance

I made a little Collections Crib Sheet to help me keep them all straight. Vector and Hashtable are kind of old school and I usually use the newer collections. They are synchronized, and that may be enough reason to use them some times. But we can get synchronized versions of the newer collections from the Collections class, so I stick with the new ones.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi

Please don't post the same question twice. It just wastes our time and yours.
As for learning more about Collections. You should check out the Java Tutorial in the link in my signature. It has a section that is all about the Collections API.
