java wait 和notify的用法
package com.test; public class OutputThread implements Runnable { private int num; private Object lock; public OutputThread(int num, Object lock) { super(); this.num = num; this.lock = lock; } public void run() { try { while(true){ synchronized(lock){ lock.notifyAll(); lock.wait(); System.out.println(num); } } } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } public static void main(String[] args){ final Object lock = new Object(); Thread thread1 = new Thread(new OutputThread(1,lock)); Thread thread2 = new Thread(new OutputThread(2, lock)); thread1.start(); thread2.start(); } }
