Question

请各位JAVA编程高手帮我个忙。我编的一个程序出现错误。但不知道错那里了。请你们指正。

public class exmm
{ public static void main(String agrs[])
{ new frame();
}
}
class frame implements Runnable
{ Thread student=new Thread(this);
Thread teacher=new Thread(this);
student.start();
teacher.start();
public void run()
{ if(Thread.currentThread()==student)
{ try
{System.out.println("张三正在睡觉不听课");
Thread.sleep(1000*60*60);
}
catch(InterruptedException e)
{ System.out.println("张三被老师吵醒");
}
System.out.println("张三开始听课");
}
else if(Thread.currentThread()==teacher)
{ try { System.out.println("上课！");
Thread.sleep(500);
}
catch(InterruptedException e){}
student.interrupt();
}

}
}

Answer 1

//错误已改正
public class exmm {
public static void main(String agrs[]) {
new frame();
}
}
class frame implements Runnable {
Thread student=new Thread(this);
Thread teacher=new Thread(this);
frame(){
student.start();
teacher.start();
}
public void run() {
if(Thread.currentThread()==student){
try{
System.out.println("张三正在睡觉不听课");
Thread.sleep(1000*60*60);
}
catch(InterruptedException e){
System.out.println("张三被老师吵醒");
}
System.out.println("张三开始听课");
}
else
if(Thread.currentThread()==teacher){
try {
System.out.println("上课！");
Thread.sleep(500);
}
catch(InterruptedException e){}
student.interrupt();
}
}
}
//运行结果
run：
张三正在睡觉不听课
上课！
张三被老师吵醒
张三开始听课
成功生成（总时间：0 秒）

Answer 2

1 类名首字母请大写
2 student.start();
teacher.start();
这怎么能写类里？ 写方法里
3 需求不明确。
