改好了,自己还是应该多看看API

其实很多东西都是很基础的.好好学吧,不要好高骛远


----------------解决方案--------------------------------------------------------
还有,我提的意见你一点都没有接受

1,类名lift应该改为Lift

2,不要用stop方法停止线程,而是自己设置一个标量,因为stop方法已经过时了

3,编码风格,你还是添加了那么多的监听器,其实一个就可以了

好好努力吧
----------------解决方案--------------------------------------------------------
[CODE]public Action(SetFrame stfm){
sf=stfm;
sf.ss.jlb[0].setForeground(Color.GREEN);

MyOutActionListener mout=new MyOutActionListener();
for(int i=0;i<10;i++){
sf.outb.outbt[i].addActionListener(mout);
sf.outb.outbt[i].setActionCommand(""+(i+1));
}
MyInActionListener min=new MyInActionListener();
for(int i=0;i<10;i++){
sf.inb.inbt[i].addActionListener(min);
sf.inb.inbt[i].setActionCommand(""+(i+1));
}


}[/CODE]

这个改一下会很难吗?

这样的话,你只生成了两个对象,而以前你却生成了二十个对象
