1、线程的生命周期

2、模拟死锁

jps:查找运行程序pid

jstack pid:查看线程栈

package com.zw.rule.service.util;

public class DeadLock {
    private static Object obj1 = new Object();
    private static Object obj2 = new Object();

    public static void main(String[] args) {
        new Thread(new Thread1()).start();
        new Thread(new Thread2()).start();
    }


    private static class Thread1 implements Runnable{

        @Override
        public void run() {
            synchronized (obj1){
                try {
                    System.out.println(">>>>>>>>>>>>>>>>"+Thread.currentThread().getName()+"获取了obj1锁");
                    Thread.sleep(3000);
                } catch (InterruptedException e) {
                    e.printStackTrace
