使用Java代码手写死锁

 1 public class DeadLockDemo extends Thread{
 2 
 3     String lockA ;
 4     String lockB;
 5     public DeadLockDemo(String name,String lockA,String lockB){
 6         super(name);
 7         this.lockA = lockA;
 8         this.lockB = lockB;
 9     }
10 
11     public void run() {
12         synchronized (lockA){
13             System.out.println(Thread.currentThread().getName() + "拿到了" + lockA + ",等待拿到" + lockB);
14             try {
15                 Thread.sleep(1000);
16                 synchronized (lockB){
17                     System.out.println(Thread.currentThread().getName() + "拿到了" + lockB);
18                 }
19             } catch (InterruptedException e) {
20                 e.printStackTrace();
21             }
22 
23         }
24     }
25 
26     public static void main(String[] args){
27         String lockA = "lockA";
28         String lockB = "lockB";
29         DeadLockDemo threadA = new DeadLockDemo("ThreadA", lockA, lockB);
30         DeadLockDemo threadB = new DeadLockDemo("ThreadB", lockB, lockA);
31         threadA.start();
32         threadB.start();
33         try {
34             threadA.join();
35             threadB.join();
36         } catch (InterruptedException e) {
37             e.printStackTrace();
38         }
39     }
40 }

ThreadA拿到了lockA,等待拿到lockB
ThreadB拿到了lockB,等待拿到lockA
