使用java语言编写一个抽奖系统
package ch07;
import javax.swing.*;
public class Test2 {
public static void main(String[] args) {
String output="";
output+="恭喜第"+(1+(int)(Math.random()*100))+"号中了一等奖";
output+="\n恭喜第"+(1+(int)(Math.random()*100))+"号"+(int)(1+(Math.random()*100))+"号"+"中了二等奖";
for(int i=0;i3;i++){
output+="\n恭喜第"+(1+(int)(Math.random()*100))+"号中了三等奖";
}
JOptionPane.showMessageDialog(null, output);
}
}

中奖的人是随机的！

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 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";
}
}
