java 线程死锁的小例子

public class TestDeadLock implements Runnable
{
	public int flag = 1;
	static Object o1= new Object(); 
	static Object o2 = new Object();

	/**
	 * @param args
	 */
	public static void main(String[] args)
	{
		TestDeadLock td1 = new TestDeadLock();
		TestDeadLock td2 = new TestDeadLock();
		td1.flag=1;
		td2.flag=0;
		Thread t1 = new Thread(td1);
		Thread t2 = new Thread(td2);
		t1.start();
		t2.start();
	}

	public void run()
	{
		if(flag == 1){
			synchronized(o1){
				try
				{
					Thread.sleep(500);
				}
				catch (InterruptedException e)
				{
				}
				synchronized(o2){
					System.out.println("1");
				}
			}
		}
		if(flag==0){
			synchronized(o2){
				try
				{
					Thread.sleep(500);
				}
				catch (InterruptedException e){
				}
				synchronized(o1){
					System.out.println("0");
				}
			}
		}
	}
