### 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18
    售票点1:您成功购买到一张票，余票剩余17
