Java中多线程的使用（超级超级详细）线程安全原理解析 4

package ThreadSafe;

public class Main {
    public static void main(String[] args) {
    //使用同一个对象
        ThreadSafe threadSafe = new ThreadSafe();
        Thread  one = new Thread(threadSafe, "一号");
        Thread two = new Thread(threadSafe, "二号");
        Thread three = new Thread(threadSafe, "三号");
        one.start();
        two.start();
        three.start();
    }
}

package ThreadSafe;

public class ThreadSafe implements Runnable {
    private  int ticketsum=100;
    public  void  run(){
      while(true){
          if (ticketsum>0){
              try {
                  Thread.sleep(10);
              } catch (InterruptedException e) {
                  e.printStackTrace();
