初识并发问题

package com.thread.test5;

//多个线程操作同一个对象
//买火车票的例子

//发现问题：多个线程操作同一个资源的情况下，线程不安全，数据紊乱
public class TestThread implements Runnable{

    //票数
    private int ticketNums = 10;
    
    @Override
    public void run() {
        while(true){
            if(ticketNums<=0){
                break;
            }
			
			//模拟延时
            try {
                Thread.sleep(200);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

            System.out.println(Thread.currentThread().getName()+"-->拿到了第"+ ticketNums-- +"票");
        }
    }

    public static void main(String[] args) {
        TestThread testThread = new TestThread();

        new Thread(testThread,"小明").start();
        new Thread(testThread,"老师").start();
        new Thread(testThread,"黄牛党").start();

    }
