Java Wait Function

Question

I was wondering if you guys could help me out. I\'m trying to make an animation program with Java\'s built in graphics module... The thing is, Java executes everything at once;

Answer 1

Maybe a simple sleep might be enough for you?

Thread.sleep(milliseconds);

Answer 2

Create a javax.swing.Timer that executes each X milliseconds, and draws one frame each time it is triggered.

This is the example from the javadoc:

  int delay = 1000; //milliseconds
  ActionListener taskPerformer = new ActionListener() {
      public void actionPerformed(ActionEvent evt) {
          //...Perform a task...
      }
  };
  new Timer(delay, taskPerformer).start();

Modify the delay, to e.g. 20ms. That will give you about 50 frames per second if your painting doesn't take too long.
