写了一个java中线程同步的死锁问题，但是输出结果就是不对，劳烦前辈指点指点。源代码如下：
public class TestDeadLock implements Runnable{
public static int flag = 1;
static Object o1 = new Object();
static Object o2 = new Object();
public void run(){
System.out.println("flag=" + flag);
if(flag == 1){
synchronized(o1){
try{
Thread.sleep(500);
}catch(Exception e){
e.printStackTrace();
}
synchronized(o2){
System.out.print("1");
}
}
if(flag == 0){
synchronized(o2){
try{
Thread.sleep(500);
}catch(Exception e){
e.printStackTrace();
}
synchronized(o1){
System.out.print("0");
}
}
}
}
public static void main(String[] args) {
TestDeadLock testDeadLock1 = new TestDeadLock();
TestDeadLock testDeadLock2 = new TestDeadLock();
testDeadLock1.flag = 1;
testDeadLock2.flag = 0;
Thread t1 = new Thread(testDeadLock1);
Thread t2 = new Thread(testDeadLock2);
t1.start();
t2.start();
}
}
输的结果一直不是期待的那样子
