OK, when you get an exception here's a good tip: READ IT! It's saying that the index is out of bounds. That's a good hint. It says the index is 1 while the size (of the ArrayList) is 0.

Another good idea is checking the JavaDocs for what you're having problems with. For example, the ArrayList#add(i nt, E) function. That will tell you that an IndexOutOfBound sException is thrown "if the index is out of range (index < 0 || index > size())". Which explains the problem and should help you to solve your situation.
