Java DeadLock

public class TestDeadLock implements Runnable{public int flag = 1;static Object o1 = new Object(),o2 = new Object();public void run(){System.out.println("flag = "+flag);if(flag==1){synchronized(o1){try{Thread.sleep(500);//o1 sleeps so that t2 can lock o2;}catch(Exception e){e.printStackTrace();}synchronized(o2){System.out.println("11");//can't print;}}}if(flag ==0){synchronized(o2){   // t2 Locks o2try{Thread.sleep(5000);}catch(Exception e){e.printStackTrace();}synchronized(o1){System.out.println("00");//can't print;}}}}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();}}

结果：flag = 1

     flag = 0
