Hi, I am writing a simple animation application.It is supposed to countinuosly shows a word on the screen and every 30 ms change the location of the word according to a formula. I thought that it had to worked automatically using Thread but after showing the word on the screen for the first time , it do not change the position of the word.Actually I was expected to have from Main() -> Start() -> Run() (updating position and also the screen using repant())if I add ex.start() at the end of the main() everything works but the background do not update.

You need to put ex.start() in main, because even though it created it, it will not start the thread without that being called. Likewise, to stop it, you will eventually need to call ex.stop().
I am not sure what you mean exactly by the background does not update, but I am guessing you mean the old words do not disappear. This is because you are overriding paint(), and if I remember correctly, repaint() calls paint, which at this time is only writing the string to the screen. Perhaps you should put what is in paint() at this time in a method by another name...call that new method, and then repaint();
