本文介绍了两种在Java中创建多线程的方式：一是通过实现Runnable接口，二是直接继承Thread类。这两种方法都可以实现并发购票的功能，详细探讨了各自的应用场景和优缺点。

主方法：

package com.duoxiancheng;

public class SellTicketsMain {
    public SellTicketsMain() {}
    public static void main(String[] args){
          //调用Runnable实现
//        SellTicketsThread sellTicketsThread = new SellTicketsThread();
//        Thread w1 = new Thread(sellTicketsThread,"窗口1");
//        Thread w2 = new Thread(sellTicketsThread,"窗口2");
//        Thread w3 = new Thread(sellTicketsThread,"窗口3");
//        Thread w4 = new Thread(sellTicketsThread,"窗口4");
//        Thread w5 = new Thread(sellTicketsThread,"窗口5");

        //继承Thread实现
        SellTicketsThread2 w1 = new SellTicketsThread2("窗口1");
        SellTicketsThread2 w2 = new SellTicketsThread2("窗口2");
        SellTicketsThread2 w3 = new SellTicketsThread2("窗口3");
        SellTicketsThread2 w4 = new SellTicketsThread2("窗口4");
        SellTicketsThread2 w5 = new SellTicketsThread2("窗口5");

        w1.start();
        w2.start();
        w3.start();
        w4.start();
        w5.start();
    }


}

方法一：实现Runnable接口

package com.duoxiancheng;

public class SellTicketsThread implements Runnable{

    private int ticketCount = 50;
    static Object lock = "aa";
    public SellTicketsThread(){}

    @Override
    public void run() {
        while (ticketCount>0){
            synchronized (lock){
                if(ticketCount > 0){
                    System.out.println(Thread.currentThread().getName()+"正在卖第："+ticketCount+"张票"+",还剩"+(ticketCount-1)+"张票");
                    ticketCount--;
                    if (ticketCount == 0){
                        System.out.println("票已卖完");
                    }
                }else {
                    System.out.println("票已卖完");
                }
            }
            try {
                Thread.sleep(1000);
            }catch (InterruptedException e){
                e.printStackTrace();
            }

        }
    }
}

方法二：继承Thread

package com.duoxiancheng;

public class SellTicketsThread2 extends Thread {
    public SellTicketsThread2(String name){
        super(name);
    }
    static int ticketCount = 50;
    static Object lock = "aa";

    @Override
    public void run() {
        while(ticketCount > 0){
            synchronized (lock){
                if (ticketCount > 0){
                    System.out.println(Thread.currentThread().getName()+"正在卖第："+ticketCount+"张票"+",还剩"+(ticketCount-1)+"张票");
                    ticketCount--;
                    if (ticketCount == 0){
                        System.out.println("票已卖完");
                    }
                }
            }
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }
        }
    }
}
