    First off, you need to fix your indentation and naming conventions (classes start with an uppercase letter). You also shouldn't have empty catch blocks.

    What is populatearrayldb? If it's a method, where are the parenthesis?

    There is a link in my signature on using code tags. Also, you could go to any of the existing posts and press the "reply with quote" button just to see what they did.

    That is not correct syntax at all. The parenthesis go after the method name. Hint: println is a method, and you're calling it correctly (well, if you call printing out a blank String correct).

    Well, does it compile? Does it run? Does it do what you want?
