实现3个卖票窗口,一共卖100张票的模拟卖票环节

package cn.code.day3_17Thread;import java.lang.Thread;import java.util.Random;public class TestThread {       public static void main(String[] args) {           //1.生成3个随机的售票数        Random r1 = new Random();        Random r2 = new Random();        int a = r1.nextInt(101);        int loss = 100 - a + 1;        int b = r2.nextInt(loss);        int c = 100-b-a;        //3.生成3个窗口        MyThread sell1 = new MyThread(a);        sell1.setName("窗口1");        MyThread sell2 = new MyThread(b);        sell2.setName("窗口2");        MyThread sell3 = new MyThread(c);        sell3.setName("窗口3");        //4.售票环节        sell1.start();        sell2.start();        sell3.start();    }}//2.设定三个售票窗口的线程,问题,如何将票数传递给线程?//通过构造函数传值class MyThread extends Thread{       private  int a;    public MyThread(int a)    {           this.a=a;    }    @Override    public void run() {           for (int i = 0; i
