员工前后门入场,并统计次数
某公司组织年会，会议入场时有两个入口，在入场时每位员工都能获取一张双色球彩票，假设公司有100个员工，
利用多线程模拟年会入场过程，并分别统计每个入口入场的人数,以及每个员工拿到的彩票的号码。线程运行后打印
格式如下：
编号为: 2 的员工 从后门 入场! 拿到的双色球彩票号码是:[17, 24, 29, 30, 31, 32, 07]
编号为: 1 的员工 从后门 入场! 拿到的双色球彩票号码是:[06, 11, 14, 22, 29, 32, 15]
//.....
从后门入场的员工总共: 13 位员工
从前门入场的员工总共: 87 位员工
题目中用到的产生双色球的工具类已经写好,可以直接使用
import java.util.Arrays;
import java.util.Random;
public class DoubleColorBallUtil {
public static String create() {
String[] red = {"01","02","03","04","05","06","07","08","09","10",
"11","12","13","14","15","16","17","18","19","20","21","22","23",
"24","25","26","27","28","29","30","31","32","33"};
//创建蓝球
String[] blue = "01,02,03,04,05,06,07,08,09,10,11,12,13,14,15,16".split(",");
boolean[] used = new boolean[red.length];
Random r = new Random();
String[] all = new String[7];
for(int i = 0;i<6;i++) {
int idx;
do {
idx = r.nextInt(red.length);//0-32
} while (used[idx]);//如果使用了继续找下一个
used[idx] = true;//标记使用了
all[i] = red[idx];//取出一个未使用的红球
}
all[all.length-1] = blue[r.nextInt(blue.length)];
Arrays.sort(all);
return Arrays.toString(all);
}
}
测试类:
public class Test07 {
public static void main(String[] args) {
Staff staff = new Staff();
new Thread(staff, "前门").start();
new Thread(staff, "后门").start();
}
}
线程类:
class Staff implements Runnable {
//员工人数100人
private int num = 100;
@Override
public void run() {
String colorBall;//双色球变量
int count = 0;//统计数量
String name = Thread.currentThread().getName();
while (true) {
synchronized (this) {
if (num > 0) {
colorBall = DoubleColorBallUtil.create();
System.out.println("编号为:" + num + "的员工从" + name + "入场!拿到双色球的号码是:" + colorBall);
num--;//进一个员工,少一个员工
count++;//计数加一
//休眠
try {
Thread.sleep(20);
} catch (InterruptedException e) {
e.printStackTrace();
}
} else {
System.out.println("从"+name+"入场的员工共有:" + count + "位员工");
break;
}
}
}
}
}
打印结果:
