go语言抽奖程序 编写抽奖程序

能帮忙用java做一个抽奖程序吗，就是简单的一，二，三等奖，特等奖。谢谢

找了两组程序：

代码一：

import java.awt.*;

import java.awt.event.*;

import javax.swing.*;

class GoodLucky extends JFrame implements ActionListener

{

JTextField tf = new JTextField();

JButton b1 = new JButton("开始");

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("祝大家鸿运！");

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();

}

}

代码二：

import java.awt.BorderLayout;

import java.awt.Container;

import java.awt.Font;

import java.awt.event.MouseAdapter;

import java.awt.event.MouseEvent;

import javax.swing.JButton;

import javax.swing.JLabel;

import javax.swing.JPanel;

import javax.swing.JTextField;

public class LuckyNumberInterface extends JFrame {

JLabel ltitle = new JLabel("欢迎使用本抽奖机", JLabel.CENTER);

JLabel linput = new JLabel("幸运号码：");

JTextField input = new JTextField(20);

JButton btnStart = new JButton("开始");

JButton btnStop = new JButton("停止");

JPanel lpanel = new JPanel();

JPanel btnPanel = new JPanel();

public LuckyNumberInterface() {

super("抽奖机");

final LuckyNumber ln = new LuckyNumber(input);

ln.start();

Container container = getContentPane();

lpanel.add(linput);

lpanel.add(input);

btnPanel.add(btnStart);

btnPanel.add(btnStop);

Font font = new Font("宋体", Font.BOLD, 16);

ltitle.setFont(font);

container.add(ltitle, BorderLayout.NORTH);

container.add(lpanel, BorderLayout.CENTER);

container.add(btnPanel, BorderLayout.SOUTH);

btnStart.addMouseListener(new MouseAdapter() {

@Override

public void mouseClicked(MouseEvent arg0) {

ln.setFlag(true);

}

});

btnStop.addMouseListener(new MouseAdapter() {

@Override

public void mouseClicked(MouseEvent arg0) {

ln.setFlag(false);

}

});

setDefaultCloseOperation(EXIT_ON_CLOSE);

setSize(400, 120);//设置窗口的显示大小

setLocation(400, 300);//设置窗口显示的位置

setVisible(true);//显示窗口

}

public static void main(String[] args) {

new LuckyNumberInterface();

}

}

package com.softeem.lesson03;

import java.text.DecimalFormat;

import java.util.Random;

import javax.swing.JTextField;

public class LuckyNumber extends Thread {

private String luckyNumber = "";

private boolean flag = false;//开关

private JTextField input;

public LuckyNumber(JTextField input) {

this.input = input;

}

public void setFlag(boolean flag) {

this.flag = flag;

}

@Override

public void run() {

while (true) {

if (flag) {

generatorLuckyNumber();

}

}

}

public void generatorLuckyNumber() {

String[] firstNumber = { "130", "131", "134", "137", "135", "139",

"150", "151", "155", "158", "159" };

Random rd = new Random();

int number = rd.nextInt(10000);

DecimalFormat df = new DecimalFormat("0000");

String lastNumber = df.format(number);

luckyNumber = firstNumber[rd.nextInt(firstNumber.length)] + "****"

+ lastNumber;

input.setText("");

input.setText(luckyNumber);

}

}

相关问答

Q1: 大家帮我看看这个go语言程序运行怎么不出结果啊？

这个，os的args应该是 从0开始的index吧。另外你运行这个，如果只用go run，或者 build之后，只是执行这个程序，不加参数，os.Args应该只有1个元素也就是说len(os.Args) == 1. 这样显然循环不会执行啊……

Q2: 利用dreamweaver制作一个随机抽奖的网页程序！！急急急！

这个需要java去编程个软甲才能实现每次点击所产生的结果不一样。
