Java死锁

使用线程模拟一个死锁

package com.wxh.thread;

public class Test_Dead {
	
	public static void main(String[] args) {
		DeadThread dt=new DeadThread();
		new Thread(dt,"张三").start();
		new Thread(dt,"李四").start();
	}
}

class DeadThread implements Runnable{
	private Object o1=new Object();
	private Object o2=new Object();
	
	public void run() {
		if(Thread.currentThread().getName().equals("张三")){
			method1();
		}else{
			method2();
		}
	}
	
	public void method1(){
		synchronized (o1) {
			System.out.println(Thread.currentThread().getName()+"haha,我拿到o1锁");
			try {
				Thread.sleep(500);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			synchronized (o2) {
				System.out.println("我执行完了");
			}
		}
	}
	
	public void method2(){
		synchronized (o2) {
			System.out.println(Thread.currentThread().getName()+"haha,我拿到o2锁");
			try {
				Thread.sleep(500);
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
			synchronized (o1) {
				System.out.println("我执行完了");
			}
		}
	}
	
}
