Java模拟双色球彩票游戏（超级简单的逻辑）

综合案例开发：模拟双色球彩票游戏

玩法说明：

双色球投注区分为红球号码区和蓝球号码区，红球号码范围为01～33，蓝球号码范围为01～16。双色球每期从33 个红球中开出6个号码（不能重复），从16个蓝球中开出1个号码作为中奖号码，双色球玩法即是竞猜开奖号码的6 个红球号码和1个蓝球号码，顺序不限。 用户输入红球和蓝球号码，程序输出该用户中几等奖。

代码实现：

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

public class SimulatedLottery {

	public static void main(String[] args) {
		//单注最高奖金
		int maxMoney = 500;
		//输入蓝球的号码
		System.out.print("请输入你购买的蓝球号码：");
		Scanner input = new Scanner(System.in);
		int blueBall = input.nextInt();
		//输入红球的数组
		int[] redBall = new int[6];
		System.out.print("请输入你购买的红球号码(不重复)：");
		for (int i = 0; i < redBall.length; i++) {
			redBall[i] = input.nextInt();
		}
		//输出输入值
		System.out.println("----------------");
		System.out.print("你购买的红球号码是：");
		for (int i = 0; i < redBall.length; i++) {
			System.out.print(redBall[i]+",");
		}
		System.out.println();
		System.out.println("你购买的蓝球号码是："+blueBall);
		System.out.println("---正在产生中奖号码---");
		
		//生成的蓝球号码
		Random numsRandom = new Random();
		int blueBallRandom = numsRandom.nextInt(16)+1;
		
		//生成红球的号码
		int[] redBallRandom = new int[6];
		int index = redBallRandom.length;
		int inputRandom = 0;
		int k = 0;
		while (index>0) {
			
			if (exist(redBallRandom, inputRandom)) {
				//在数组中存在,更换一个随机数
				inputRandom = numsRandom.nextInt(33)+1;
			}else {

				redBallRandom[k] = inputRandom;
				k++;
				index--;
			}
		}
		
		//输出中奖号码
		System.out.println("蓝球的中奖号码是："+blueBallRandom);
		System.out.print("红球的中奖号码是：");
		for (int i = 0; i < redBallRandom.length; i++) {

		}
		System.out.println();

		
		//统计和蓝球相等的个数
		int blueCount = 0;
		if (blueBall == blueBallRandom) {
			blueCount = 1;
		}
		
		//统计和红球相等的个数
		int redCount = 0;
		for (int i = 0; i < redBallRandom.length; i++) {
			if (redBall[i] == redBallRandom[i]) {
				redCount++;
			}
		}
		
		
		//判断是否中奖
		if (blueCount == 0 && redCount <= 3) {
			//未中奖
			System.out.println("很遗憾，您未中奖，赌博害人，请勿上头！");
			//中奖
		}else if(blueCount == 1 && redCount < 3) {
			System.out.println("恭喜你，中了六等奖，您的奖金为5元");
			
		}else if((blueCount == 1 && redCount == 3) || (blueCount == 0 && redCount == 4)) {
			System.out.println("恭喜你，中了五等奖，您的奖金为10元");
			
		}else if((blueCount == 1 && redCount == 4) && (blueCount == 0 && redCount == 5)) {
			System.out.println("恭喜你，中了四等奖，您的奖金为200元");
			
		}else if(blueCount == 1 && redCount == 5) {
			System.out.println("恭喜你，中了三等奖，您的奖金为3000元");
			
		}else if(blueCount == 0 && redCount == 6) {
			System.out.println("恭喜你，中了二等奖，您的奖金为"+(int)(maxMoney*0.3)+"万");

		}
		
		
	}
