I want to extract particular elements from an arraylist.
If arraylist contains elements : Rajkumar , Shashii , Hari Kumar , paters , nam kumar

I want to take elements ending with kumar i.e. Rajkumar, Hari Kumar , nam kumar
How can i do it through efficient coding
Thanx in advance

Well, lists are not sorted -- so I don't think there is anything more efficient than to just use an iterator, and checking each string member with its endsWith() method.
