⑴ 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
importjava.util.Random;
publicclassTest{
publicstaticvoidmain(String[]args){
intstuNums=30;
int[]nums=newint[stuNums];//存储学号的数组
boolean[]flags=newboolean[stuNums];//标记,用于标记对应下标的学号是否已经被抽取过了
for(inti=0;i<stuNums;i++){
nums[i]=i+1;//给学号赋值
}
Randomr=newRandom();
while(true){
intindex=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(inti=0;i<2;i++){
intindex=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(inti=0;i<3;i++){
intindex=r.nextInt(stuNums);
if(!flags[index]){
System.out.println("c等:"+nums[index]);
flags[index]=true;
}else{
i--;
}
}
}
}
集合法
importjava.util.ArrayList;
importjava.util.Collections;
publicclassTest2{
publicstaticvoidmain(String[]args){
intstuNums=20;
ArrayList<Integer>list=newArrayList<Integer>();
for(inti=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));
}
}
⑵ 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";
}
}
⑶ 抽奖Java程序(是作业,急需
本来老早都给你弄好了,可你也不操心,一直没有给你发;现在就这样,需要改的话,说一下
/**
* 根据倒叙的字符串,获取与最后一位相同的位数
* @param string -倒叙后的字符串
* @return -后几位相同
*/
public static int getString( String string){
String string1 = string+"-";
//正则
String[] arr1 = string1.split(string1.toCharArray()[0]+"");
String string2 = string1.substring(0,arr1.length-1)+"-";
String[] arr2 = string2.split(string2.toCharArray()[0]+"");
return arr1.length==arr2.length?arr1.length-1:
getString(string.substring(0,arr1.length-1))
;
}
/**
* 后几位相同
* @param num
* @return
*/
public static int get(Integer num,Integer o){
String string = (num+o)+"";
StringBuffer buffer = new StringBuffer(string);
string = buffer.reverse().toString();//字符串倒叙
int count = getString(string);
return count==3&&o==0?3:
count==4&&o==0?2:
count==6&&o==0?1:
count==3&&o==1?31:
count==4&&o==1?21:
count==6&&o==1?11:
count==3&&o==-1?32:
count==4&&o==-1?22:
count==6&&o==-1?12: -1;
}
public static void main(String[] args) {
Map<String,String> map = new TreeMap<>();
Set<Integer> set = new HashSet<>();
set.add(402223);
set.add(402221);
set.add(401223);
set.add(401221);
set.add(222223);
set.add(222221);
int b = 0,n=30;
while (true){
int random = (int) (Math.random()*(1000000-100000) + 100000);
set.add(random);
if (set.size() == n){
break;
}
}
for (Integer key:set){
int count = get(key,0);
//最后一个数字是0或9的话就只有一个
count = count < 0&&key%10!=9?get(key,1):count;
count = count < 0&&key%10!=1?get(key,-1):count;
String str = count>0?(
count/10==0?(
count==3?"third":count==2?"second":"first"
)
:(
"adjacent"
)
):
"blank";
//"欢迎再来";
map.put("买到的号码:"+key, str);
}
System.out.println(map);
}
⑷ 通过java 实现 模拟抽奖
import java.util.Scanner;
public class Choujiang {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);//定义Scanner类1234
System.out.println("请输入四位卡号:");//输入提示语
int cardNo = sc.nextInt();//接受输入数据
int gewei = cardNo%10;//分解个位
int shiwei = cardNo/10%10;//分解十位
int wei = cardNo/100%10;//分解百位
int qianwei = cardNo/1000;//分解千位
int sum = gewei+shiwei+wei+qianwei;
System.out.println("会员卡号四位之和是:"+sum);
if(sum>20){//判断各位数和是否大于20
System.out.println("恭喜,你是幸运客户!");
}else{
System.out.println("谢谢惠顾!");
}
}
}
⑸ 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);
}
}
程序运行结果截图
中奖的人是随机的!

⑺ 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!
}.
