Refreshing a JPanel-Moving a JLabel?

Your code is causing a long-running process to run on the Swing event thread which is preventing this thread from doing its necessary actions: paint the GUI and respond to user input. This will effectively put your entire GUI to sleep.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
