## 例题：模拟火车站售票程序，开启三个售票窗口 ##

package com.lcy;
    
    public class Ticket implements Runnable { 
        private int tick = 100;
    
        @Override
        public void run() { 
            while (true) { 
                if (tick > 0) { 
                    try { 
                        Thread.sleep(100);
                    } catch (InterruptedException e) { 
                        e.printStackTrace();
                    }
                    System.out.println(Thread.currentThread().getName() + "售出车票，tick号码为：" + tick);
                    tick--;
                } else { 
                    break;
                }
            }
        }
    
        Ticket t = new Ticket();
        Thread t1 = new Thread(t);
        Thread t2 = new Thread(t);
        Thread t3 = new Thread(t);
    
            t1.setName("t1窗口");
            t2.setName("t2窗口");
            t3.setName("t3窗口");
    
            t1.start();
            t2.start();

# 通过“售票问题”来说明什么是安全问题 #

**问题：**  
在卖票的过程中，出现了重票和错票------>则意味着出现了安全问题。

**出现的原因：**  
当某个线程操作车票的过程中，尚未完成操作时，其他线程参与进来也操作车票。

**如何解决：**  
当一个线程a操作ticket 的时候，其他线程不能参与进来，直到线程a操作完ticket时，其他的线程才可以开始操作ticket，这种情况即使线程a出现了阻塞，也不能被改变。

**在Java中：**  
是通过同步机制来解决线程的安全问题

**同步的好处：**  
解决了线程的安全问题

**同步的局限性：**  
操作同步代码时，只能有一个线程参与，其他的线程等待，相当于是一个单线程的过程，效率低。

# 5、Synchronized的使用方法 #

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzMjI5NTQz_size_16_color_FFFFFF_t_70 25]

## 同步代码块的说明 ##

**操作共享数据的代码即为需要被同步的代码**

**共享数据**：  
多个线程共同操作的变量：比如火车售票问题的ticket

**同步监视器**  
俗称锁，任何一个类的对象都可以充当锁。但是要求多个线程必须共用同一把锁。

## 解决上面火车售票中出现的安全问题 ##

**1、实现Runnable接口**  
**注意要保证共用同一把锁**  
**任意对象Object object = new Object(); 或者用当前对象 this**

package com.lcy;
    
    public class Ticket implements Runnable { 
        private int tick = 100;
        Object object = new Object();
    
        @Override
        public void run() { 
            while (true) { 
                synchronized (object) { 
                    if (tick > 0) { 
                        try { 
                            Thread.sleep(100);
                        } catch (InterruptedException e) { 
                            e.printStackTrace();
                        }
                        System.out.println(Thread.currentThread().getName() + "售出车票，tick号码为：" + tick);
                        tick--;
                    } else { 
                        break;
                    }
                }
            }
        }
    
        public static void main(String[] args) { 
            Ticket t = new Ticket();
            Thread t1 = new Thread(t);
            Thread t2 = new Thread(t);
            Thread t3 = new Thread(t);
    
            t1.setName("t1窗口");
            t2.setName("t2窗口");
            t3.setName("t3窗口");
    
            t1.start();
            t2.start();
            t3.start();
        }
    }

**2、继承Thread**  
**注意要保证共用同一把锁**

private static int tick = 100;
    private static Object obj = new Object();

package com.lcy;
    
    public class Ticket2 extends Thread { 
        private static int tick = 100;
        private static Object obj = new Object();
    
        @Override
        public void run() { 
            while (true) { 
                synchronized (obj) { 
                    if (tick > 0) { 
                        try { 
                            Thread.sleep(100);
                        } catch (InterruptedException e) { 
                            e.printStackTrace();
                        }
                        System.out.println(Thread.currentThread().getName() + "售出车票，tick号码为：" + tick);
                        tick--;
                    } else { 
                        break;
                    }
                }
            }
        }
    
        public static void main(String[] args) { 
            Ticket2 t1 = new Ticket2();
            Ticket2 t2 = new Ticket2();
            Ticket2 t3 = new Ticket2();
    
            t1.setName("窗口1");
            t2.setName("窗口2");
            t3.setName("窗口3");
    
            t1.start();
            t2.start();
            t3.start();
        }
    }

**3、同步方法**

package com.lcy;
    
    public class Ticket3 implements Runnable { 
        private int tick = 100;
    
        @Override
        public void run() { 
            while (true) { 
                show();
            }
        }
    
        public synchronized void show() { 
            synchronized (this) { 
                if (tick > 0) { 
                    try { 
                        Thread.sleep(100);
                    } catch (InterruptedException e) { 
                        e.printStackTrace();
                    }
                    System.out.println(Thread.currentThread().getName() + "售出车票，tick号码为：" + tick);
                    tick--;
                }
            }
        }
    
        public static void main(String[] args) { 
            Ticket3 t = new Ticket3();
            Thread t1 = new Thread(t);
            Thread t2 = new Thread(t);
            Thread t3 = new Thread(t);
    
            t1.setName("t1窗口");
            t2.setName("t2窗口");
            t3.setName("t3窗口");
    
            t1.start();
            t2.start();
            t3.start();
        }
    }

**可以看到此时就没有出现安全问题了。**
