I am currently making a program for the Android platform but I need some help, I am pretty new to Java/Eclipse. Here's the deal:One of the features that the program will have is allowing you to select items from a list that are sorted in groups (groups form a list of their own (a list in a list if you put it like that)) and the program needs to make a list out of those items that you have selected. Then the program needs to compare that list with one or more lists of the same sort and see which items are matching and make yet another list of those matching items. Now, since I am really new into programming with Java and the SDK can anyone help me get an idea of the best way to do this? There needs to be a LOT of items in the starting lists (more than 500), so should I put them in some sort of a database? Also, the same item can be in several groups, but it needs to be the SAME item (if I check one in the first group it needs to be checked in the second group too).Thanks in advance and since this is my first time posting sorry if I did anything wrong!
