Java多线程：多线程模拟抢票应用

实现代码

package com.oumuv.ticket;
/** * 多线程抢票应用 */
public class TicketModel { 
    public static void main(String[] args) { 
        TicketModel ticketModel = new TicketModel();
        Ticket ticket = ticketModel.new Ticket(20);//设置余票数
        TicketConsumer ticketConsumer = ticketModel.new TicketConsumer("售票点1", ticket);
        TicketConsumer ticketConsumer2 = ticketModel.new TicketConsumer("售票点2", ticket);
        TicketConsumer ticketConsumer3 = ticketModel.new TicketConsumer("售票点3", ticket);
        new Thread(ticketConsumer).start();
        new Thread(ticketConsumer2).start();
        new Thread(ticketConsumer3).start();
    }
    /** *余票 */
    class Ticket { 
        int num;
        public Ticket(int num) { 
            this.num = num;
        }
    }
    /** *售票端 */
    class TicketConsumer implements Runnable { 
        String name;
        Ticket ticket;
        public TicketConsumer(String name, Ticket ticket) { 
            this.name = name;
            this.ticket = ticket;
        }
        @Override
        public void run() { 
            while (true) { 
                synchronized (ticket) { 
                    if (ticket.num > 0) { 
                        System.out.println(name + ":您成功购买到一张票，余票剩余" + (--ticket.num));
                        try { 
                            Thread.sleep(100);
                        } catch (InterruptedException e) { 
                            e.printStackTrace();
                        }
                    } else { 
                        System.out.println(name + ":余票不足，购买失败");
                        break;
                    }
                }
            }
        }
    }
}

可能输出的结果

售票点1:您成功购买到一张票，余票剩余19
售票点1:您成功购买到一张票，余票剩余18
售票点1:您成功购买到一张票，余票剩余17
售票点1:您成功购买到一张票，余票剩余16
售票点1:您成功购买到一张票，余票剩余15
售票点1:您成功购买到一张票，余票剩余14
售票点1:您成功购买到一张票，余票剩余13
售票点1:您成功购买到一张票，余票剩余12
售票点1:您成功购买到一张票，余票剩余11
售票点1:您成功购买到一张票，余票剩余10
售票点1:您成功购买到一张票，余票剩余9
售票点1:您成功购买到一张票，余票剩余8
售票点1:您成功购买到一张票，余票剩余7
售票点3:您成功购买到一张票，余票剩余6
售票点3:您成功购买到一张票，余票剩余5
售票点3:您成功购买到一张票，余票剩余4
售票点2:您成功购买到一张票，余票剩余3
售票点2:您成功购买到一张票，余票剩余2
售票点2:您成功购买到一张票，余票剩余1
售票点2:您成功购买到一张票，余票剩余0
售票点3:余票不足，购买失败
售票点1:余票不足，购买失败
售票点2:余票不足，购买失败
