If this is homework: Give it a try yourself, come back with specific coding problems and someone will help you. We will not however do your work for you. If this is paid work: You should not be employed as a programmer.

Easily... Take Jamie's advice. Post some code that illustrates you can put forth some effort in finding the solution yourself. Until you post code that appears to be close to working (or that we feel was typed in a good-faith effort to solve the problem), and with specific problems/questions, we will not help. -Jeff

First sort the lists, then you can loop through them side by side and compare the items to find out where they match and where there are items that exist in only one of the lists.

Experience is the sum of all the mistakes you have done.

He can loop through the first ArrayList and use the .Contains(object item) method for the second array list and not interate through both ArrayLists. just a thought
