Java用do-while循环写出一个抽奖程序
//这个是我习惯的包名，呵呵package com.james.wk;import java.util.Random;
import java.util.Scanner;public class guess {
public static boolean getIt() {
Scanner input = new Scanner(System.in);
Random ra = new Random();
System.out.println("请输入你的会员号：");
int a=0; //初始化会员号
a = input.nextInt();
int b = ra.nextInt(10); //随机数
System.out.println("幸运数是：" + b);
int c = 0; //定义a的百位数
if (a = 999 || a = 10000) {
System.out.println("请输入四位数");
getIt();
}
c = a / 100 % 10;
if (b == c) {
return true;
}
return false;
} public static void main(String[] args) {
String sure=null;
do{
System.out.println("是否开始猜奖？（任意键开始，’N‘下次退出）");
sure=new Scanner(System.in).next();
if(sure.toLowerCase().equals("n")){
System.out.println("您已经退出！");
return;
}else{
if (new guess().getIt()) {
System.out.println("恭喜你是猜到了！");
} else {
System.out.println("猜错了");
}
}
}while(1==1);
}
}
会有点漏洞，会员号输入时验证不能为其他字符没有做，不好意思
用java写一个抽奖程序
你是要JAVA可视化的 还是控制台的啊？
控制台的话 你可以用循环来取中奖号，将其存入list或set里（最好是set，因为set本来就不会重复）。如果用list存就另外写一个循环方法，来挨个判定该元素是不是已经在list中存在了，如果存在，就让选号的再加选一次，如果不重复，就放到list里去。。。。OK
Java代码实现抽奖:从班级的学号中抽出一个一等奖,两个二等奖,三个三等奖
抽取问题, 重点是 同一个学号不能重复被抽取.
解决办法很多,
比如数组可以使用下标来标记,号码是否被使用,使用了就继续下一次抽取
也可以使用集合来抽取,把集合顺序打乱,然后随便抽几个就可以了
参考代码:数组法
import java.util.Random;
public class Test {
public static void main(String[] args) {
int stuNums=30;
int[] nums=new int[stuNums];//存储学号的数组
boolean[] flags=new boolean[stuNums];//标记,用于标记对应下标的学号是否已经被抽取过了
for (int i = 0; i stuNums; i++) {
nums[i]=i+1;//给学号赋值
}
Random r=new Random();
while(true){
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("A等:"+nums[index]);
flags[index]=true; //标记已经被使用过了
break;
}
}
for (int i = 0; i 2; i++) {
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("B等:"+nums[index]);
flags[index]=true;
}else{
i--;//如果已经被抽取过了 ,那么i建议,再次循环
}
}
for (int i = 0; i 3; i++) {
int index = r.nextInt(stuNums);
if(!flags[index]){
System.out.println("c等:"+nums[index]);
flags[index]=true;
}else{
i--;
}
}
}
}
集合法
import java.util.ArrayList;
import java.util.Collections;
public class Test2 {
public static void main(String[] args) {
int stuNums=20;
ArrayListInteger list=new ArrayListInteger();
for (int i = 0; i stuNums; i++) {
list.add(i+1);
}
System.out.println("有序"+list);
Collections.shuffle(list);//打乱顺序
System.out.println("乱序"+list);
System.out.println("A等"+list.get(0));
System.out.println("B等"+list.get(1));
System.out.println("B等"+list.get(2));
System.out.println("C等"+list.get(3));
System.out.println("C等"+list.get(4));
System.out.println("C等"+list.get(5));
}
}
java抽奖程序
public String[] findluckMen(String[] data , int n){
Random random = new Random();
int len = data.length;
String[] luckmen = new String[len];
for(int i=0;ilen;i++){
int index = random.nextInt(len);
luckmen[i] = data[index ];
}
return luckmen;
}
JAVA抽奖问题
import java.util.Scanner;public class TextRandom {
public static Scanner input=new Scanner(System.in);
public static int count=0;//记录用户猜对的次数
public static int xitong =(int)Math.round(Math.random()*10);//系统产生的随机数0~10之间
public static int w[]=new int[3];//将系统随即产生的数字放在数组W中
public static int guess[]=new int [3];
public static void main(String[]args)
{
guess();
}
public static void guess()
{ //开始抽奖
for(int j=0;jw.length;j++){
System.out.println("开始抽奖，请用户输入0~10之间的数字，请输入第"+(j+1)+"个数字");
guess[j] =input.nextInt();
if(j2){
System.out.println("正在摇奖，需要中途放弃么 ？(y/n)");
String shuru =input.next();
if(shuru.equals('y')) break;
}
}
//系通开出的奖
System.out.println("系统产生三个数字是：");
for(int i=0;i3;i++)
{
System.out.print((int)Math.round(Math.random()*10));
w[i]=(int)Math.round(Math.random()*10);
}
//兑奖过程
for(int i=0;i3;i++)
{
if(guess[i]==w[i])
{
count++;//记录出用户抽中奖的次数
}
}
if(count==3)
{
System.out.println("恭喜你，你中奖了 ");
}
else
{
System.out.println("很遗憾，您没有中奖，欢迎下次再来！");
}
}
}
//我已尽力了
