You need to increment the x,y coordinates on the timer until it arrives at the new location - not so much 'jump' as 'move'

You should do your jump in a separate thread:

 public void jump() {
    Thread jumpThread = new Thread() {
      public void run() {
        try {
          int speed=-30;
          for(int i=0;i<60;i++){
            p.setY(speed);
            speed+=1;
            repaint();
            sleep(20);
          }
        } catch (Exception e) {
          e.printStackTrace();
        }
      }
    };
    jumpThread.start();
}
