跪求Java高手帮忙在我的程序上补写画笔程序，急需~

是实现java的鼠标事件吧，就是可以在窗体上画画写字什么的？

// TODO Auto-generated method stub
this.addMouseListener(this);
}
@Override
public void paint(Graphics g) {
// TODO Auto-generated method stub
g.setColor(Color.yellow);//鼠标画线的颜色
g.drawLine(sx,sy, ex,ey);
}
@Override
public void update(Graphics g) { //重写update方法画线什么的 在写的时候就不会被清除
// TODO Auto-generated method stub
this.paint(g);
}
@Override
public void stop() {
