商场推出幸运抽奖活动的java初级代码编写
public class Lucky {
public static void main(String[] args){
System.out.println("请输入您java集群抽奖代码的4位会员卡号:");
Scanner sc = new Scanner(System.in);
int number = sc.nextInt(); //接收用户从控制台输入java集群抽奖代码的会员卡号java集群抽奖代码，并保存在会员卡号变量中
int a = number/1000; //千位
int b = number%1000/100; //百位
int c = number%100/10; //十位
int d = number%10; //个位
if((a+b+c+d)20){
System.out.println("恭喜中奖!您是幸运客户");
}else{
System.out.println("谢谢参与!");
}
}
}

Q1: 能不能帮我写一个模拟抽奖机的JAVA代码 1到32的八个数字
代码如下：
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Luck extends JFrame implements ActionListener{
JTextField tf = new JTextField();
JButton b1 = new JButton("开始");
JButton b2 = new JButton("停止");
boolean isGo = false;
public Luck(){
b1.setActionCommand("start");
JPanel p = new JPanel();
p.add(b1);
p.add(b2);
b1.addActionListener(this);
b2.addActionListener(this);
b2.setEnabled(false);
this.getContentPane().add(tf,"North");
this.getContentPane().add(p,"South");
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setSize(300,200);
this.setLocation(300,300);
Cursor cu = new Cursor(Cursor.HAND_CURSOR);
this.setCursor(cu);
this.setVisible(true);
tf.setText("welcome you! ");
this.go();
}
public void go(){
while(true){
if(isGo == true){
String s = "";
for(int j = 1; j = 8;j++){
int i = (int)(Math.random() * 31) + 1;
if(i 10){
s = s + " 0" + i;
}else{
s = s + " " + i;
}
}
tf.setText(s);
}
try{
Thread.sleep(10);
}catch(java.lang.InterruptedException e){
e.printStackTrace();
}
}
}
public void actionPerformed(ActionEvent e){
String s = e.getActionCommand();
if(s.equals("start")){
isGo = true;
b1.setEnabled(false);
b2.setEnabled(true);
}else{
isGo = false;
b2.setEnabled(false);
b1.setEnabled(true);
}
}
public static void main(String[] args){
new Luck();
}
}
看下是你的要求不。若有疑问Hi我。
Q2: 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));
}
}
Q3: java抽奖程序
public String[] findluckMen(String[] data , int n){
Random random = new Random();
int len = data.length;
String[] luckmen = new String[len];
for(int i=0;ilen;i++){
int index = random.nextInt(len);
luckmen[i] = data[index ];
}
return luckmen;
}

Q5: 公司年会要进行抽奖活动java代码实现
参考
int custNO;//客户会员号（说明:customer指客户）
System.out.println ("请输入四位会员卡号:");//输入会员卡号
Scanner input = new Scanner(System.in);
custNO = input.nextInt();
if (custNo 1000){
//获得每位数字(a/b是除a%b是取余)
int gewei = custNO % 10 ; //分解获得个位数 1001 %10 ==1
int shiwei = custNO /10 %10 ; //分解获得十位数 //1234 /10 % 10 = 123 %10 =3 (1234 /10 = 123.4 % 10 )
int baiwei = custNO /100 %10 ;//分解获得百位数
int qianwei = custNO /1000 ; //分解获得千位数
}
//计算数字之和
int sum = gewei + shiwei + baiwei + qianwei ;
System.out.println ("会员卡号"+custNO +"各位之和:" + sum );
