AppletEvent 这是继承的什么类.我也初学有好多东西都没用上,帮不上你

public void init(){
    font=new Font("TimesRoman",Font.BOLD,63);
}
public void init(){
font=new Font("TimesToman",Font.BOLD,64);

}
这样可以吗
我不知道

楼主想让别人帮你什么

还有一点,尽量不要用非标准包里面的类

尽量只用java以及javax开头的包

repaint();
try{
clodkThread.sleep(1000);
}catch(InterruptdeException e)
{
    }

}

写错了

public void stop(){
    clockThread.stop();
}
}
一般都不提倡这么结束一个线程,最好在run的内部按一个开关让线程在他自己的内部结束.
