maybe the code | int[] names= {"jim","john","tom","mick","bodger","badger"}; | should be like | String[] names= {"jim","john","tom","mick","bodger","badger"}; | And the int[] type in your first method is a bit tricky if you want to do null test....I would like to use the Integer[] or better yet, List in your case....
