能幫忙用java做一個(gè)抽獎(jiǎng)程序嗎，就是簡(jiǎn)單的一，二，三等獎(jiǎng)，特等獎(jiǎng)。謝謝

找了兩組程序：

成都創(chuàng)新互聯(lián)公司，專(zhuān)注為中小企業(yè)提供官網(wǎng)建設(shè)、營(yíng)銷(xiāo)型網(wǎng)站制作、響應(yīng)式網(wǎng)站開(kāi)發(fā)、展示型成都網(wǎng)站設(shè)計(jì)、做網(wǎng)站、成都外貿(mào)網(wǎng)站建設(shè)公司等服務(wù)，幫助中小企業(yè)通過(guò)網(wǎng)站體現(xiàn)價(jià)值、有效益。幫助企業(yè)快速建站、解決網(wǎng)站建設(shè)與網(wǎng)站營(yíng)銷(xiāo)推廣問(wèn)題。

代碼一：

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

class GoodLucky extends JFrame implements ActionListener

{

JTextField tf = new JTextField();

JButton b1 = new JButton("開(kāi)始");

JButton b2 = new JButton("停止");

boolean sg=false;

public GoodLucky(){

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("祝大家鴻運(yùn)！");

this.go();

}

public void go()

{

while(true)

{

if(sg==true)

{

String s = " ";

for(int j = 1; j = 7;j++)

{

int i = (int)(Math.random() * 9) + 1;

if(i 10)

{

s = s + " 0" + i;

}

else

{

s = s + " " + i;

}

}

tf.setText(s);

}

try

{

Thread.sleep(100);

}

catch(java.lang.InterruptedException e)

{

e.printStackTrace();

}

}

}

public void actionPerformed(ActionEvent e)

{

String s = e.getActionCommand();

if(s.equals("start"))

{

sg = true;

b1.setEnabled(false);

b2.setEnabled(true);

}

else

{

sg= false;

b2.setEnabled(false);

b1.setEnabled(true);

}

}

public static void main(String[] args)

{

new GoodLucky();

}

}

抽獎(jiǎng)程序 用JAVA做 求代碼

這里是提問(wèn)和回答用的。寫(xiě)的時(shí)候遇到什么困難可以問(wèn)的。用隨機(jī)數(shù)，抽中一個(gè)就不要再次抽中同樣的號(hào)碼，就可以了。

java抽獎(jiǎng)程序

我給你個(gè)比較簡(jiǎn)單的，，但是需要按照你的要求進(jìn)行稍微的修改。。然后在main方法中去執(zhí)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(gòu)物管理系統(tǒng) 幸運(yùn)抽獎(jiǎng)\n");

do{

// 需要的話(huà)請(qǐng)把隨機(jī)數(shù)調(diào)整成你想要的范圍（我這個(gè)是為了測(cè)試方便寫(xiě)的1

（～3的隨機(jī)數(shù)，根據(jù)你的需要把下面的3換成你想要的數(shù)字就行了）

int num=(int)(Math.random()*3+1);

System.out.print("請(qǐng)輸入會(huì)員卡號(hào)(4位整數(shù))：");

custNo=input.nextInt();

//百位數(shù)與隨機(jī)數(shù)相同的為幸運(yùn)者

int bai=custNo/100%10;

while(i==1){

if(custNo=1000custNo=9999){

break;

}

else{

System.out.println("\n會(huì)員號(hào)碼輸入有誤，請(qǐng)重新輸入：");

custNo=input.nextInt();

continue;

}

}

if(bai==num){

showAward();

System.out.print("\n卡號(hào)："+custNo+"是幸運(yùn)客戶(hù)，獲得"+awardName);

}else{

System.out.print("\n卡號(hào)："+custNo+"\t謝謝您的支持！");

}

System.out.println("\n是否繼續(xù)(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(qǐng)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";

}

}

Java代碼實(shí)現(xiàn)抽獎(jiǎng):從班級(jí)的學(xué)號(hào)中抽出一個(gè)一等獎(jiǎng),兩個(gè)二等獎(jiǎng),三個(gè)三等獎(jiǎng)

抽取問(wèn)題, 重點(diǎn)是 同一個(gè)學(xué)號(hào)不能重復(fù)被抽取.

解決辦法很多,

比如數(shù)組可以使用下標(biāo)來(lái)標(biāo)記,號(hào)碼是否被使用,使用了就繼續(xù)下一次抽取

也可以使用集合來(lái)抽取,把集合順序打亂,然后隨便抽幾個(gè)就可以了

參考代碼:數(shù)組法

import?java.util.Random;

public?class?Test?{

public?static?void?main(String[]?args)?{

int?stuNums=30;

int[]?nums=new?int[stuNums];//存儲(chǔ)學(xué)號(hào)的數(shù)組

boolean[]?flags=new?boolean[stuNums];//標(biāo)記,用于標(biāo)記對(duì)應(yīng)下標(biāo)的學(xué)號(hào)是否已經(jīng)被抽取過(guò)了

for?(int?i?=?0;?i??stuNums;?i++)?{

nums[i]=i+1;//給學(xué)號(hào)賦值

}

Random?r=new?Random();

while(true){

int?index?=?r.nextInt(stuNums);

if(!flags[index]){

System.out.println("A等:"+nums[index]);

flags[index]=true;?//標(biāo)記已經(jīng)被使用過(guò)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--;//如果已經(jīng)被抽取過(guò)了?,那么i建議,再次循環(huán)

}

}

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);//打亂順序

System.out.println("亂序"+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));

}

}
