夏夏历险记

public class UpDown2 extends Applet implements Runnable {
  static int RADIUS = 20;
  static int x = 30;
  public int y = 30;
  Thread t;
  public void init () {
  t = new Thread (this); // What does this mean in this statement?
  t.start ();
  }
Please master to explain to me the use of this, a little embarrassing.
