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:
目前成都创新互联公司已为近1000家的企业提供了网站建设、域名、网页空间、网站托管、服务器租用、企业网站设计、城口网站维护等服务,公司将坚持客户导向、应用为本的策略,正道将秉承"和谐、参与、激情"的文化,与客户和合作伙伴齐心协力一起成长,共同发展。
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 bai=custNo/100%10;
while(i==1){
if(custNo=1000custNo=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(bai==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";
}
}
用java完成一个抽奖的程序。 每次运行程序,都会从以下的抽奖结果中随机显示一个出来:
生成100个对象,对象有个属性,其中10个是大奖,40个是小奖,50个是无奖。
放到一个List里。
每次抽中的步骤
1、随机生成0-List长度之间的数值 ,去取List中的相应对象,并移除这个对象。
代码如下。:
奖品对象类:
public class PrizeBean {
private String type;
public String getType() {
return eggType;
}
public void setType(String eggType) {
this.eggType = eggType;
}
}
奖品池初始化代码段:
{
List prizebeanList = new ArrayList();
for (int i = 0; i 10; i++) {
PrizeBean prizeBean = new PrizeBean();
prizeBean.setType(“大奖“);
prizebeanList.add(prizeBean);
}
for (int i = 0; i 40; i++) {
PrizeBean prizeBean = new PrizeBean();
prizeBean.setType(“小奖“);
prizebeanList.add(prizeBean);
}
for (int i = 0; i 50; i++) {
PrizeBean prizeBean = new PrizeBean();
prizeBean.setType(“无奖“);
prizebeanList.add(prizeBean);
}
}
抽奖代码段:
/**
*奖品池已经空的,肯定返回无奖了。。。
**/
if(prizebeanList.size()==0){
- 没有中奖哦,下次加油!
return;
}
/**
* 随机生成,奖品池中奖品数量的数字。。取出奖品池中的数字。。移除记录。返回。。
*/
int resultnum = (int) (Math.random() * prizebeanList.size());
PrizeBean resultPrizeBean = prizebeanList.get(resultnum);
prizebeanList.remove(resultPrizeBean);
if(resultPrizeBean.getType() .eqauls("大奖"){
- 恭喜,大奖!
}else if(resultPrizeBean.getType() .eqauls("小奖"){
- 运气不错哦,小奖!
}else{
- 没有中奖哦,下次加油!
}.
用swing编写一个java抽奖的程序,至少有5个按钮,显得高大上一点。

用Java 编一个抽奖程序
用一个Int[]数组记录随机到的数字,
插代码:
int[] count=new i[6];//用于接收生成的随机数
for(int i=0;ii.length;i++)
{
Random rand = new Random(); int c = rand.nextInt(); //int范围类的随机数 c = rand.nextInt(30); //生成0-30以内的随机数 c = (int)(Math.random() * 30); //0-30以内的随机数 count[i]=c;}
能帮忙用java做一个抽奖程序吗,就是简单的一,二,三等奖,特等奖。谢谢

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));
}
}
