java抽獎程序

A. 用java編寫一個彩票抽獎程序

我寫給你，如果是本專業，以後要多多學習。JDK 1.6

import java.awt.GridLayout;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.util.Iterator;
import java.util.Random;
import java.util.Set;
import java.util.TreeSet;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JTextField;

public class LuckyDrawn {

private JFrame f = new JFrame("Lucky Drawn");
private JButton btn = new JButton("Drawn");
private JTextField result = new JTextField("Result");
private static final int MIN = 1;
private static final int MAX = 30;
private static final int RESULT_COUNT = 7;

public LuckyDrawn(){
f.add(btn);
f.add(result);
result.setEditable(false);

btn.addMouseListener(new MouseListener(){

public void mouseClicked(MouseEvent e) {

Random rand = new Random();

Set<Integer> set = new TreeSet<Integer>();

while(set.size() < RESULT_COUNT){
set.add(new Integer(rand.nextInt(MAX)+ 1));
}

StringBuffer sb = new StringBuffer("Lucky numbers are: ");
for (Iterator iter = set.iterator(); iter.hasNext();) {
sb.append(((Integer) iter.next()).intValue()).append(", ");
}

result.setText(sb.substring(0, sb.length() - 2).toString());
f.pack();
}

public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
});

f.setLayout(new GridLayout(2, 1));
f.setVisible(true);
f.setLocation(500, 200);
f.pack();
f.validate();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

public static void main(String[] args) {
new LuckyDrawn();
}

}

B. java抽獎程序

我給你個比較簡單的，，但是需要按照你的要求進行稍微的修改。。然後在main方法中去執行就可以了：
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我行我素購物管理系統 > 幸運抽獎\n");

do{
// 需要的話請把隨機數調整成你想要的范圍（我這個是為了測試方便寫的1
（～3的隨機數，根據你的需要把下面的3換成你想要的數字就行了）
int num=(int)(Math.random()*3+1);
System.out.print("請輸入會員卡號(4位整數)：");
custNo=input.nextInt();
//百位數與隨機數相同的為幸運者
int =custNo/100%10;
while(i==1){
if(custNo>=1000&&custNo<=9999){
break;
}
else{
System.out.println("\n會員號碼輸入有誤，請重新輸入：");
custNo=input.nextInt();
continue;
}
}

if(==num){
showAward();
System.out.print("\n卡號："+custNo+"是幸運客戶，獲得"+awardName);
}else{
System.out.print("\n卡號："+custNo+"\t謝謝您的支持！");
}
System.out.println("\n是否繼續(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";
}

}

C. 用java寫一個抽獎程序

這一百個隨機數給個范圍 random(范圍),再分批獲取唄 ,獲取到的數判斷在list里存在不,存在就重新獲取,不存在就添加到list中去

D. 如何用java寫一個抽獎程序 web類型的

問題一：前兩天剛寫的動態滾動條的廣告。可以模仿下。用循環做出n個div裡面的內容是姓名，樣式怎麼好看怎麼定。吧這些div放在大的div裡面用var timer = setInterval讓這些div滾動，速度慢了是廣告，快了就是抽獎。給一個按鈕，點擊停止滾動 clearInterval(timer). 這樣效果就好了。
這個是廣告的連接：http://..com/question/198782458298926805.html?oldq=1

G. 抽獎Java程序（是作業，急需

本來老早都給你弄好了,可你也不操心,一直沒有給你發;現在就這樣,需要改的話,說一下

* @return -後幾位相同
*/
public static int getString( String string){

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))
;
}

H. 抽獎程序 用JAVA做 求代碼

這里是提問和回答用的。寫的時候遇到什麼困難可以問的。用隨機數，抽中一個就不要再次抽中同樣的號碼，就可以了。

I. 用swing編寫一個java抽獎的程序，至少有5個按鈕，顯得高大上一點。

J. 用java做一個抽獎的代碼

要在cmd下運行啊 我想你安裝JDK沒？

import java.util.*;
class Test{
private int maxSize=0;
private int selectSize=0;
private List<Integer> list=new ArrayList<Integer>();
private int[] one=new int[7];
public Test(int maxSize,int selectSize){
this.maxSize=maxSize;
this.selectSize=selectSize;
one=new int[selectSize];
for(int i=1;i<=maxSize;i++)
list.add(Integer.valueOf(i));
}

public void open(){
List<Integer> temp=new ArrayList<Integer>();
temp.addAll(list);
int[] p=new int[selectSize];
int tag=0;
for(int i=0;i<selectSize;i++){
tag=(int)(Math.random()*555555%temp.size());
p[i]=(Integer)temp.get(tag).intValue();
temp.remove(tag);
}
one=p;

}
public void paixu(){
int temp=0;
for(int i=0;i<selectSize;i++){
for(int j=0;j<selectSize-1;j++){
if(one[j]>one[j+1]) {temp=one[j];one[j]=one[j+1];one[j+1]=temp;}
}
}
}

public void printOpen(){
open();
paixu();
for(int i=0;i<one.length;i++)
System.out.print(one[i]+" ");
System.out.println();
}
static public void main(String[] str){
Test t=new Test(33,6); //彩票類型：33選6
for(int i=0;i<10;i++) //開10次獎
t.printOpen();

}
}
