Take a shot at it first, figuring it out is part of the learning process... We can't give you a hint, if we don't know where you are stuck.

I think his point was that you should try it yourself, and ask specific questions. Look up linear search and binary search algorithms and try to implement one of those, and if you have specific questions ask. Linear search is easier to start off with. Your question is to general to be able to properly answer it without doing the work for you.


A linear search is very simple. Start at the beggining of the data structure, see if it is what you are looking for, if not move to the next element. Rinse and repeat until you get to the end of the ArrayList.
