Java编程之多线程死锁与线程间通信简单实现代码

public class MyDeadLockTest { public static void main(String[] args){  Object obj1 = new Object();  Thread thread1 = new Thread(new DeadRes(true,obj1));  Thread thread2 = new Thread(new DeadRes(false,obj1));  thread1.start();  thread2.start(); }}class DeadRes implements Runnable{ boolean flag; Object obj; public DeadRes(boolean flag, Object obj1) {  this.flag = flag;  this.obj = obj1; } @Override public void run() {   if(flag){    synchronized (DeadRes.class){     System.out.println(Thread.currentThread().getName()+" acquie lock is DeadRes.class");     synchronized (obj){      System.out.println(Thread.currentThread().getName()+" acquie lock is obj");     }    }   }else{    synchronized (obj){     System.out.println(Thread.currentThread().getName()+" acquie lock is obj");     synchronized (DeadRes.class){      System.out.println(Thread.currentThread().getName()+" acquie lock is DeadRes.class");     }    }   } }}
