双色球中奖大学生作业Java编程基础包含键盘录入以及随机数生成

需求：抽双色球，红色球6个，蓝色球1个。

要求随机生成中奖号，用户键盘录入自己的号码，根据中奖号判断用户是否中奖。

 以下是全部代码：

package com.lqm.basicTest;

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

public class test9 {
    public static void main(String[] args) {
        /*双色球：6个红色球：编号1-33。1个绿色球，编号1-16。求用户是否中奖*/

        //1.调用中奖的球号的函数
        int[] winNumber = createNumber();
        for (int i = 0; i < winNumber.length; i++) {
            System.out.print(winNumber[i]+" ");
        }

        //2.用户输入彩票号码（红球+蓝球）
        int[] userInputArr = userInputNumber();

        //3.判断用户的中奖情况
        //红球 蓝球
        int redCount = 0;
        int blueCount = 0;
        //中奖红球个数
        for (int i = 0; i < winNumber.length - 1; i++) {
            for (int j = 0; j < userInputArr.length; j++) {
                if(winNumber[i] == userInputArr[j]) {
                    redCount++;
                    break;
                }
            }
        }
        //中奖蓝球个数
        if(winNumber[winNumber.length-1] == userInputArr[userInputArr.length-1]) {
            blueCount++;
        }
        //根据红球蓝球的个数判断中奖情况
        if(redCount == 6 && blueCount == 1) {
            System.out.println("恭喜你，中奖1000万");
        } else if(redCount == 6 && blueCount == 0) {
