简单的写了一下：

package test;

public class test {
public static final Object lock = new Object();
public static void main(String[] args){
MyThread mt = new MyThread();
System.out.println("-------Main Thread starts subthread-----");
mt.start();
try{
System.out.println("-------Main thread falls into sleep-----");
Thread.sleep(5000);
synchronized (test.lock){
System.out.println("-------Main thread wakes up subthread-----");
test.lock.notifyAll();
}
}catch(Exception e){
}
System.out.println("-------Main thread finished-----");
}
}

class MyThread extends Thread{
public void run(){
System.out.println("-------SubThread starts-----");

synchronized (test.lock){
System.out.println("Subthread begins to wait.....");
try{
test.lock.wait();
}catch(Exception e){

}
}
System.out.println("SubThread wakes up and continue.....");
System.out.println("-------SubThread thread finished-----");
}

}
