线程同步问题

[chinadrencher]

我在一个程序里启动一个线程,

在这个程序里,有不有办法不用循环的方式等待线程运行结束?

必须用线程的原因是 线程里需要定期监控一个变化.直到这个变化到了.才开始执行主控程序的下面的内容.

请赐教.

join();

yeah, details:
in main process call
Thread.getCurrentThread().join();

wait() 和notice()机制

class MainThread{
public static void main (String[] args){
...
TaskThread tt=new TaskThread ();
tt.start();
synchronized(tt){
tt.wait()
}
}
}

class TaskThread extends Thread{
public void run(){
...
//doing task
noticeAll();
...
}
}

[treeroot]

Thread.getCurrentThread().join();

what are you going to do??
Who is so stupid to wait till himself's death?

[treeroot]

Thread a=new Thread(target);
a.start();
a.join();
//wait until a is dead!
