摇号抽奖软件 必须用Java编写

import java.awt.event.WindowAdapter;

import java.awt.event.WindowEvent;

import java.util.Random;

import javax.swing.JFrame;

import javax.swing.JTextField;

public class RandomTest extends JFrame implements Runnable {

JTextField tf = new JTextField();

public RandomTest() {

this.add(tf);

this.setSize(300,200);

this.setVisible(true);

this.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

// System.exit(0);

dispose();

}

});

}

public void run() {

String[] list = { "aaa", "123", "张三", "李四" };

int time = 100; //3秒钟出结果

Random rd = new Random(); // 随机数生成类

int i = 0;

while (time 0) {

try {

i = rd.nextInt(list.length);

tf.setText(list[i]);

Thread.sleep(10);

time --;

} catch (InterruptedException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

tf.setText("获奖者:" + list[i]);

}

public static void main(String[] args) {

new Thread(new RandomTest()).start();

}

}

跪求:用Java设计抽奖程序

程序循环应该写在开始按钮的监听里,当按下开始按钮后,程序开始循环,当按停止按钮时,循环停止. 你可以用while循环, 条件是一个boolean型的值,当按开始值为true,当按停止值为false.

java语言实现一个摇号系统，但是可以内部设定中奖名单这个怎么实现？

1、简单控制台程序如下，如需界面需要自己加个。

package zhidao;

import java.util.HashSet;

import java.util.Random;

import java.util.Scanner;

import java.util.Set;

/**

* @author bufei

* @datetime 2020年8月31日15:54:11

*/

public class YaoHao {

public static void main(String[] args) {

String xian = "= = = = = = = = =";

// 起点        终点     奖个数          指定的号码个数

int start = 0, end = 0, prizeNum = 0, defaNum = 0;

System.out.println(xian);

System.out.println("欢迎使用xxx 抽奖系统！");

System.out.println(xian);

Scanner scanner = new Scanner(System.in);

System.out.println("请输入号码范围例如 1 10：");

start = scanner.nextInt();

end = scanner.nextInt();

System.out.println("请输入奖项个数：");

prizeNum = scanner.nextInt();

System.out.println("请输入指定中奖号码个数，不指定请输入0：");

defaNum = scanner.nextInt();

int[] defa = new int[defaNum];

if (defaNum != 0) {

System.out.println("请输入指定的中奖号码，空格隔开:");

for (int i = 0; i defaNum; i++) {

defa[i] = scanner.nextInt();

}

}

System.out.println(xian);

System.out.println("本次抽奖中奖号码为：");

for (int num : randomDraw(start, end, prizeNum, defa)) {

System.out.print(num+" ");

}

}

/**

* @param start    抽奖范围起点

* @param end      抽奖号码范围终点

* @param prizeNum 中奖号码个数

* @param defa     指定中奖号码

* @return

*/

public static SetInteger randomDraw(int start, int end, int prizeNum, int[] defa) {

SetInteger set = new HashSet();

// 未指定中奖号码

if (defa.length == 0) {

//随机抽 prizeNum 个奖

while (set.size() prizeNum) {

set.add(new Random().nextInt(end - start + 1) + start);

}

return set;

} else {

//指定了中奖号码

//把指定的号码加入进去

for (int num : defa) {

set.add(num);

}

//如果没有全部指定 则继续抽剩余的奖项

while (set.size() prizeNum - defa.length) {

set.add(new Random().nextInt(end - start + 1) + start);

}

return set;

}

}

}

2、运行效果如图

指定了中奖号码

未指定中奖号码
