Ok, im having EXTREME problems, with arraylists, i simply dont understand them, yes i have read your article. Would someone just take a look at this code, i know it sucks. Look at the areas that say "HELP!!!" next to them. But basicly i want to take data from textfields and put them into an arraylist. So the user inputs data, name, address, age all that, hits save (This is when it goes into the arraylist) the textfields clear, and they are ready to input another set of data into the array. Help me out guys, thanks alot!
