太长了,我把中间JPanel的代码给切了,要紧吗?
----------------解决方案--------------------------------------------------------
SetFrame的代码呢?

详细问题描述?
----------------解决方案--------------------------------------------------------
class MyActionListener implements ActionListener{
public void actionPerformed(ActionEvent ae){
floor=Integer.parseInt(ae.getActionCommand());
sf.liftTwo.sbp.jbt[floor-1].setForeground(Color.BLUE);
person_num=(int)(1+Math.random()*20);//电梯最多20人
threadStart();
}
}
刚才还有一个版主说,因为我的启动是单击启动.所以运行后只能有一部电梯有反应.
问题是ActionTwo actTwo=new ActionTwo(sf);
ActionOne actOne=new ActionOne(sf);
这两个谁放前面谁有反应,但我要两个都有

1,程序设计不合理,你的起动线程的时候,根本就没有管以前的线程有没有被销毁.并且你的run方法里面,没有sleep,这样会造成CPU瞬间使用量非常高
2,停止线程不能用stop方法
你的监听器没有必要注册那个多,一个就够了
