java實現抽獎

Ⅰ 求java實現轉盤轉動功能，抽獎，坐等

轉盤轉動就是圖片，定義一個隨機數random；
if(random==1){
畫中獎的圖片
}else｛
畫不中獎的圖片｝

Ⅱ 用java怎麼實現控制中獎率

可以做到！用 Random 得到隨機的數，再根據你的登陸人的身份 控制隨機的次數是多少！
例如：
1 - 20 為中獎， 普通就隨機出 10000個數。會員的話就隨機100個數就好了！

Ⅲ 用java寫一個抽獎程序

這一百個隨機數給個范圍 random(范圍),再分批獲取唄 ,獲取到的數判斷在list里存在不,存在就重新獲取,不存在就添加到list中去

Ⅳ 用java做一個抽獎的代碼

要在cmd下運行啊 我想你安裝JDK沒？

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); //彩票類型：33選6
for(int i=0;i<10;i++) //開10次獎
t.printOpen();

}
}

Ⅳ 使用java語言編寫一個抽獎系統

packagech07;

importjavax.swing.*;

publicclassTest2{

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

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

}

程序運行結版果截圖

中獎的人權是隨機的！

Ⅵ java抽獎程序

我給你個比較簡單的，，但是需要按照你的要求進行稍微的修改。。然後在main方法中去執行就可以了：
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我行我素購物管理系統 > 幸運抽獎\n");

do{
// 需要的話請把隨機數調整成你想要的范圍（我這個是為了測試方便寫的1
（～3的隨機數，根據你的需要把下面的3換成你想要的數字就行了）
int num=(int)(Math.random()*3+1);
System.out.print("請輸入會員卡號(4位整數)：");
custNo=input.nextInt();
//百位數與隨機數相同的為幸運者
int =custNo/100%10;
while(i==1){
if(custNo>=1000&&custNo<=9999){
break;
}
else{
System.out.println("\n會員號碼輸入有誤，請重新輸入：");
custNo=input.nextInt();
continue;
}
}

if(==num){
showAward();
System.out.print("\n卡號："+custNo+"是幸運客戶，獲得"+awardName);
}else{
System.out.print("\n卡號："+custNo+"\t謝謝您的支持！");
}
System.out.println("\n是否繼續(y/n)");
answer=input.next();
while(i==1){
if(answer.equals("y")||answer.equals("n")){
break;
}else{
System.out.print("輸入有誤！請重新輸入：");
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="美的微波爐";
}
else{
awardName="美的電飯鍋";
}

}

Ⅶ 如何用java技術實現幸運抽獎活動系統

import java.util.Scanner;
public class LuckyNumber {
/**
* 幸運抽獎
*/
public static
void main(String[] args) {
String answer
= "y"; // 標識是否繼續
String
userName = ""; // 用戶名
String
password = ""; // 密碼
int cardNumber
= 0; // 卡號
boolean
isRegister = false; // 標識是否注冊
boolean
isLogin = false; // 標識是否登錄
int max =
9999;
int min =
1000;
Scanner input
= new Scanner(System.in);
do {
System.out.println("*****歡迎進入獎客富翁系統*****");
System.out.println("\t1.注冊");
System.out.println("\t2.登錄");
System.out.println("\t3.抽獎");
System.out.println("***************************");
System.out.print("請選擇菜單：");
int choice =
input.nextInt();
switch
(choice) {
case 1:
System.out.println("[獎客富翁系統
> 注冊]");
System.out.println("請填寫個人注冊信息：");
System.out.print("用戶名：");
userName =
input.next();
System.out.print("密碼：");
password =
input.next();
//
獲取4位隨機數作為卡號
cardNumber =
(int)(Math.random()*(max-min))+min;
System.out.println("\n注冊成功，請記好您的會員卡號");
System.out.println("用戶名\t密碼\t會員卡號");
System.out.println(userName
+ "\t" + password + "\t" + cardNumber);
isRegister =
true; // 注冊成功，標志位設置為true
break;
case 2:
System.out.println("[獎客富翁系統
> 登錄]");
if
(isRegister) { // 判斷是否注冊
//
3次輸入機會
for (int i
= 1; i <= 3; i++) {
System.out.print("請輸入用戶名：");
String
inputName = input.next();
System.out.print("請輸入密碼：");
String
inputPassword = input.next();
if
(userName.equals(inputName) && password.equals(inputPassword)) {
System.out.println("\n歡迎您："
+ userName);
isLogin =
true; // 登錄成功，標志位設置為true
break;
} else if
(i < 3) {
System.out.println("用戶名或密碼錯誤，還有"
+ (3 - i) + "次機會！");
} else
{
System.out.println("您3次均輸入錯誤！");
}
}
} else
{
System.out.println("請先注冊，再登錄！");
}
break;
case 3:
System.out.println("[獎客富翁系統
> 抽獎]");
if
(!isLogin) { // 判斷是否登錄
System.out.println("請先登錄，再抽獎！");
} else
{
//生成5個4位隨機數字，並保存在數組中
int[]
luckynums = new int[5];
for(int i
= 0; i < luckynums.length; i++){
luckynums[i] =
(int)(Math.random()*(max-min))+min;
}
System.out.print("請輸入您的卡號：");
int
yourcard = input.nextInt();
int
i;
System.out.print("\n本日的幸運數字為：");
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！您是本日的幸運會員！");
break;
}
}

if (i ==
luckynums.length) {
System.out.println("\n抱歉！您不是本日的幸運會員！");
}
}
break;
default:
System.out.println("[您的輸入有誤！]");
break;
}
System.out.print("繼續嗎？（y/n）:");
answer =
input.next();
System.out.println("");
} while
("y".equals(answer));
if
("n".equals(answer)) {
System.out.println("系統退出，謝謝使用！");

}

}
}

Ⅷ 做一個JAVA的抽獎系統

用隨機的辦法 來 作為抽獎結果 是誤人的。。。。
理想辦法是生成抽獎池

然後以隨機數的辦法生成數據進入抽獎池中抽取獎品

並且加入判斷語句來過濾已經抽取出來的獎品 一直到獎池為空

Ⅸ 關於java抽獎代碼

if (b==1);{
System.out.println("您抽到的是一等獎");）
}
好像是少了{}
程序從上往下讀的 System.out.println("您抽到的是一等獎"); 不在if的裡面。
