Use a Set.

Read the Java API.

Come on Murali. Don't be childish. :p

What's tough in that? Create a Hashset and pass your ArrayList to it's constructor. This Set now removes the duplicate values as it's not allowed in it.

Then clear you ArrayList and use the addAll method to add the HashSet back to the ArrayList. Simple.

See the API documentation for the clear() and addAll(Collection c) methods.
