package com.damlab.fz;public class deadlock { public static void main(string[] args) { resource r1 = new resource(); resource r2 = new resource(); // 每个线程都拥有r1,r2两个对象 thread myth1 = new mythread1(r1, r2); thread myth2 = new mythread2(r1, r2); myth1.start(); myth2.start(); }}class resource { private int i;}class mythread1 extends thread { private resource r1, r2; public mythread1(resource r1, resource r2) { this.r1 = r1; this.r2 = r2; } @override public void run() { while (true) { // 先获得r1的锁，再获得r2的锁 synchronized (r1) { system.out.println("1号线程获取了r1的锁"); synchronized (r2) { system.out.println("1号线程获取了r2的锁"); } } } }}class mythread2 extends thread { private resource r1, r2; public mythread2(resource r1, resource r2) { this.r1 = r1; this.r2 = r2; } @override public void run() { while (true) { // 先获得r2的锁，再获得r1的锁 synchronized (r2) { system.out.println("2号线程获取了r2的锁"); synchronized (r1) { system.out.println("2号线程获取了r1的锁"); } } } }} |
运行结果：
希望本文所述对大家java程序设计有所帮助。
