I'm java beginner and I just started working with threads. Now before that I were learning about URL access and I started some simple project to make url opener with GUI that contants url field, amount and delay.

First I tried to do it without threads but gui would frezze until everything is finished, so I tried to make it with thread and failed. I really hope you can point me where is mistake I make.

EDIT: SOLVED.
Thanks for your time.
