java实现抽奖

Ⅰ 求java实现转盘转动功能，抽奖，坐等

转盘转动就是图片，定义一个随机数random；
if(random==1){
画中奖的图片
}else｛
画不中奖的图片｝

Ⅱ 用java怎么实现控制中奖率

可以做到！用 Random 得到随机的数，再根据你的登陆人的身份 控制随机的次数是多少！
例如：
1 - 20 为中奖， 普通就随机出 10000个数。会员的话就随机100个数就好了！

Ⅲ 用java写一个抽奖程序

这一百个随机数给个范围 random(范围),再分批获取呗 ,获取到的数判断在list里存在不,存在就重新获取,不存在就添加到list中去

Ⅳ 用java做一个抽奖的代码

要在cmd下运行啊 我想你安装JDK没？

import java.util.*;
class Test{
private int maxSize=0;
private int selectSize=0;
private List<Integer> list=new ArrayList<Integer>();
private int[] one=new int[7];
public Test(int maxSize,int selectSize){
this.maxSize=maxSize;
this.selectSize=selectSize;
one=new int[selectSize];
for(int i=1;i<=maxSize;i++)
list.add(Integer.valueOf(i));
}

public void open(){
List<Integer> temp=new ArrayList<Integer>();
temp.addAll(list);
int[] p=new int[selectSize];
int tag=0;
for(int i=0;i<selectSize;i++){
tag=(int)(Math.random()*555555%temp.size());
p[i]=(Integer)temp.get(tag).intValue();
temp.remove(tag);
}
one=p;

}
public void paixu(){
int temp=0;
for(int i=0;i<selectSize;i++){
for(int j=0;j<selectSize-1;j++){
if(one[j]>one[j+1]) {temp=one[j];one[j]=one[j+1];one[j+1]=temp;}
}
}
}

public void printOpen(){
open();
paixu();
for(int i=0;i<one.length;i++)
System.out.print(one[i]+" ");
System.out.println();
}
static public void main(String[] str){
Test t=new Test(33,6); //彩票类型：33选6
for(int i=0;i<10;i++) //开10次奖
t.printOpen();

}
}

Ⅳ 使用java语言编写一个抽奖系统

packagech07;

importjavax.swing.*;

publicclassTest2{

publicstaticvoidmain(String[]args){
Stringoutput="";

output+="恭喜第"+(1+(int)(Math.random()*100))+"号中了一等奖";
output+=" 恭喜第"+(1+(int)(Math.random()*100))+"号"+(int)(1+(Math.random()*100))+"号"+"中了二等奖";
for(inti=0;i<3;i++){
output+=" 恭喜第"+(1+(int)(Math.random()*100))+"号中了三等奖";
}
JOptionPane.showMessageDialog(null,output);
}

}

程序运行结版果截图

中奖的人权是随机的！

Ⅵ java抽奖程序

我给你个比较简单的，，但是需要按照你的要求进行稍微的修改。。然后在main方法中去执行就可以了：
public class GoodLuck {

int custNo;
int i=1;
String answer;
String awardName;
public void LuckNo(){

Scanner input=new Scanner(System.in);
System.out.println("\n我行我素购物管理系统 > 幸运抽奖\n");

do{
// 需要的话请把随机数调整成你想要的范围（我这个是为了测试方便写的1
（～3的随机数，根据你的需要把下面的3换成你想要的数字就行了）
int num=(int)(Math.random()*3+1);
System.out.print("请输入会员卡号(4位整数)：");
custNo=input.nextInt();
//百位数与随机数相同的为幸运者
int =custNo/100%10;
while(i==1){
if(custNo>=1000&&custNo<=9999){
break;
}
else{
System.out.println("\n会员号码输入有误，请重新输入：");
custNo=input.nextInt();
continue;
}
}

if(==num){
showAward();
System.out.print("\n卡号："+custNo+"是幸运客户，获得"+awardName);
}else{
System.out.print("\n卡号："+custNo+"\t谢谢您的支持！");
}
System.out.println("\n是否继续(y/n)");
answer=input.next();
while(i==1){
if(answer.equals("y")||answer.equals("n")){
break;
}else{
System.out.print("输入有误！请重新输入：");
answer=input.next();
continue;
}
}
}while(!answer.equals("n"));

}
public void showAward(){
int num=(int)(Math.random()*3+1);
if(num==1){
awardName="Mp3";
}
else if(num==2){
awardName="美的微波炉";
}
else{
awardName="美的电饭锅";
}

}

Ⅶ 如何用java技术实现幸运抽奖活动系统

import java.util.Scanner;
public class LuckyNumber {
/**
* 幸运抽奖
*/
public static
void main(String[] args) {
String answer
= "y"; // 标识是否继续
String
userName = ""; // 用户名
String
password = ""; // 密码
int cardNumber
= 0; // 卡号
boolean
isRegister = false; // 标识是否注册
boolean
isLogin = false; // 标识是否登录
int max =
9999;
int min =
1000;
Scanner input
= new Scanner(System.in);
do {
System.out.println("*****欢迎进入奖客富翁系统*****");
System.out.println("\t1.注册");
System.out.println("\t2.登录");
System.out.println("\t3.抽奖");
System.out.println("***************************");
System.out.print("请选择菜单：");
int choice =
input.nextInt();
switch
(choice) {
case 1:
System.out.println("[奖客富翁系统
> 注册]");
System.out.println("请填写个人注册信息：");
System.out.print("用户名：");
userName =
input.next();
System.out.print("密码：");
password =
input.next();
//
获取4位随机数作为卡号
cardNumber =
(int)(Math.random()*(max-min))+min;
System.out.println("\n注册成功，请记好您的会员卡号");
System.out.println("用户名\t密码\t会员卡号");
System.out.println(userName
+ "\t" + password + "\t" + cardNumber);
isRegister =
true; // 注册成功，标志位设置为true
break;
case 2:
System.out.println("[奖客富翁系统
> 登录]");
if
(isRegister) { // 判断是否注册
//
3次输入机会
for (int i
= 1; i <= 3; i++) {
System.out.print("请输入用户名：");
String
inputName = input.next();
System.out.print("请输入密码：");
String
inputPassword = input.next();
if
(userName.equals(inputName) && password.equals(inputPassword)) {
System.out.println("\n欢迎您："
+ userName);
isLogin =
true; // 登录成功，标志位设置为true
break;
} else if
(i < 3) {
System.out.println("用户名或密码错误，还有"
+ (3 - i) + "次机会！");
} else
{
System.out.println("您3次均输入错误！");
}
}
} else
{
System.out.println("请先注册，再登录！");
}
break;
case 3:
System.out.println("[奖客富翁系统
> 抽奖]");
if
(!isLogin) { // 判断是否登录
System.out.println("请先登录，再抽奖！");
} else
{
//生成5个4位随机数字，并保存在数组中
int[]
luckynums = new int[5];
for(int i
= 0; i < luckynums.length; i++){
luckynums[i] =
(int)(Math.random()*(max-min))+min;
}
System.out.print("请输入您的卡号：");
int
yourcard = input.nextInt();
int
i;
System.out.print("\n本日的幸运数字为：");
for (i = 0;
i < luckynums.length; i++) {
System.out.print(luckynums[i]
+ " ");\
}
for (i = 0;
i < luckynums.length; i++) {
if
(luckynums[i] == yourcard) {
System.out.println("\n恭喜！您是本日的幸运会员！");
break;
}
}

if (i ==
luckynums.length) {
System.out.println("\n抱歉！您不是本日的幸运会员！");
}
}
break;
default:
System.out.println("[您的输入有误！]");
break;
}
System.out.print("继续吗？（y/n）:");
answer =
input.next();
System.out.println("");
} while
("y".equals(answer));
if
("n".equals(answer)) {
System.out.println("系统退出，谢谢使用！");

}

}
}

Ⅷ 做一个JAVA的抽奖系统

用随机的办法 来 作为抽奖结果 是误人的。。。。
理想办法是生成抽奖池

然后以随机数的办法生成数据进入抽奖池中抽取奖品

并且加入判断语句来过滤已经抽取出来的奖品 一直到奖池为空

Ⅸ 关于java抽奖代码

if (b==1);{
System.out.println("您抽到的是一等奖");）
}
好像是少了{}
程序从上往下读的 System.out.println("您抽到的是一等奖"); 不在if的里面。
