You can only get so far by asking widely generic questions on websites like this in my opinion. There is nothing to stop you reading the Java vendor's webpages on all the API subjects you want to learn, or indeed the dozens of expert books that are online and in bookshops. But by asking us to reproduce what is already in all these sources in a more readily-digestible and unambiguous way than they already are, is a task that isn't going to help you and that few people will want to spend their time on.

Make your questions more precise, as and when you have a problem with your code, and you are likely to get a better response.

ArrayList uses an array internally to store the "list" of values.
LinkedList uses a series of elements, each pointing to the next (and previous) in the list.

The main difference is that to get an element from a linked list you need to go through all of the elements in the list (following the links).  For the array you can go directly to the element you need.  So the array list is MUCH faster when looking up values.  In return, linked list is SLIGHTLY faster when adding elements.

So 99% of the time you should be using ArrayList.  Only in very special cases (where you do lots of inserts and few lookups) would LinkedList make sense.

Hope that helps,

Doug
