对已知红包数组【9,666,188,520,99999】进行抽奖，抽到的就排除掉。-526互联

import java.util.Random;
import java.util.Scanner;

public class HelloWorld {
    public static void main(String[] args) {
        int[] money = {9,666,188,520,99999};
        aaa(money);
    }


    public static void aaa(int[] money){
        Scanner sc = new Scanner(System.in);
         Random ra = new Random();
        for (int i = 1; i <=5 ; i++) { //先让红包循环5次
            System.out.println("请您输入666抢红包");
            sc.next();  //用户输入（但不会返回值）

            while (true) {
                //生成随机数
                int suijishu = ra.nextInt(money.length);   //先弄出0-4的随机数
                int a = money[suijishu];                   //在用a接收money[suijishu]（产生的随机数就可之对应）
                if (a != 0) {
                    System.out.println("恭喜您抽到" + a + "元");
                    money[suijishu] = 0;
                    break;
                }
            }
        }
        System.out.println("游戏结束");
    }
}
