前言：

打好基础，daydayup!

题目：要求如下（同时：红球每个号码不可以相同）

编程思路：1，创建一个可以录入数字的数组；2，生成一个可以随机生成数字的数组；3，两个数组进行比较，统计相同数字。

public class shuangseqiudemo {public static void main(String[] args) {int[] xuanhao = la();System.out.println("你的号码为：");ll(xuanhao);int[] zhongjiang = lol();System.out.println("中奖号码为：");ll(zhongjiang);z(xuanhao, zhongjiang);}//1,创建一组数据public static void ll(int[] la) {System.out.print("[");for (int i = 0; i < la.length; i++) {System.out.print(i == la.length - 1 ? la[i] : la[i] + ",");}System.out.println("]");}public static int[] la() {int[] la = new int[7];Scanner sc = new Scanner(System.in);for (int i = 0; i < la.length - 1; i++) {while (true) {System.out.println("请第" + (i + 1) + "次选号(1-33)：");int num = sc.nextInt();if (num > 33 || num < 1) {System.out.println("请重新输入");} else {if (wxd(la, num)) {System.out.println("不可以重复，请重新输入");} else {la[i] = num;break;}}}}while (true) {System.out.println("输入最后一个号码（1-16）：");int num1 = sc.nextInt();if (num1 < 1 || num1 > 16) {System.out.println("请重新输入");} else {la[la.length - 1] = num1;break;}}return la;}private static boolean wxd(int[] la, int num) {for (int i = 0; i < la.length; i++) {if (la[i] == num) {return true;}}return false;}//2，创建中奖号码public static int[] lol() {int[] lol = new int[7];Random r = new Random();for (int i = 0; i < lol.length - 1; i++) {while (true) {int num2 = r.nextInt(33) + 1;//减加法 33 ==0-32 +1if (!wxd(lol, num2)) {lol[i] = num2;break;}}}lol[lol.length - 1] = r.nextInt(16) + 1;return lol;}//3,匹配中奖情况public static void z(int[] xuanhao, int[] zhongjiang) {int redcount = 0;int bucount = 0;for (int i = 0; i < zhongjiang.length - 1; i++) {for (int j = 0; j < xuanhao.length - 1; j++) {if (xuanhao[j] == zhongjiang[i]) {redcount++;break;}}}bucount = xuanhao[xuanhao.length - 1] == zhongjiang[zhongjiang.length - 1] ? 1 : 0;if (redcount == 6 && bucount == 1) {System.out.println("一等奖1000万");} else if (redcount == 6 && bucount == 0) {System.out.println("二等奖1000万");} else if (redcount == 5 && bucount == 1) {System.out.println("三等奖3000元");} else if (redcount == 5 && bucount == 0 || redcount == 4 && bucount == 1) {System.out.println("四等奖200元");} else if (redcount == 4 && bucount == 0 || redcount == 3 && bucount == 1) {System.out.println("10元");} else if (redcount < 3 && bucount == 1) {System.out.println("5元");} else {System.out.println("谢谢参与");}}
}

 实验结果：完美运行

撒花！！！！
