java多线程的条件对象和锁对象demo 利用锁对象和条件对象实现了对线程的控制，具体的讲解可以参考我的博客立即下载

package test;

	public static void main(String[] args){

	boolean flag;
	public Test1(boolean flag,Object obj1,Object obj2){

	}

	public void run() {
		 while(true){

							Thread.sleep(1000);

					 synchronized(obj1){

					 }
				 }
			 }
		 }
