源代碼：

1.創建窗體的代碼：

package?lottery;

import?java.awt.Color;

import?java.awt.Font;

import?javax.swing.JFrame;

import?javax.swing.JTextArea;

public?class?LotteryFrame {

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

JFrame frame=new?JFrame();

frame.setSize(868, 552);

frame.setLocationRelativeTo(null);

????frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

????frame.setUndecorated(true);

????frame.setLayout(null);

????Lotterypanel panel=new?Lotterypanel();

????panel.setBounds(0, 0, 868, 552);

????frame.add(panel);

????frame.setVisible(true);

????panel.addMouseListener(panel);

}

}

package?lottery;

import?java.awt.Color;

import?java.awt.Font;

import?javax.swing.JFrame;

import?javax.swing.JTextArea;

public?class?LotteryFrame {

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

JFrame frame=new?JFrame();

frame.setSize(868, 552);

frame.setLocationRelativeTo(null);

????frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

????frame.setUndecorated(true);

????frame.setLayout(null);

????Lotterypanel panel=new?Lotterypanel();

????panel.setBounds(0, 0, 868, 552);

????frame.add(panel);

????frame.setVisible(true);

????panel.addMouseListener(panel);

????}

}

2.創建面板的代碼：

package?lottery;

import?java.awt.Color;

import?java.awt.Font;

import?java.awt.Graphics;

import?java.awt.event.MouseEvent;

import?java.awt.event.MouseListener;

import?java.io.BufferedReader;

import?java.io.FileNotFoundException;

import?java.io.InputStreamReader;

import?java.util.ArrayList;

import?javax.swing.ImageIcon;

import?javax.swing.JPanel;

public?class?Lotterypanel?extends?JPanel implements?MouseListener,Runnable{

//定義初始量

String name="李菲菲";

String phone="13978673456";

boolean?isStart=true;

int?count=0;

int?y=222;

int?n=0;

int?id=0;

boolean?isMove=false;

//定義集合

ArrayList<String>data=new?ArrayList<String>();

ArrayList<String>result=new?ArrayList<String>();

private?int?i;

//讀取txt文件

public?Lotterypanel(){

read();

//創建線程

new?Thread(this).start();

}

public?void?read(){

try?{

BufferedReader br=new?BufferedReader(new?InputStreamReader(new?FileInputStream("src/lottery/lottery.txt")));

String str="";

while((str=br.readLine())!=null){

data.add(str);

count++;

id++;

????????????}

} catch?(Exception e) {

// TODO?Auto-generated catch block

e.printStackTrace();

}

}

public?void?paint(Graphics g){

super.paint(g);

//讀寫圖片

????g.drawImage(new?ImageIcon("img/case05/back2.jpg").getImage(), 0, 0,null);

????g.drawImage(new?ImageIcon("img/case05/close.png").getImage(), 840, 12,null);

????g.drawImage(new?ImageIcon("img/case05/again.png").getImage(), 645, 426,null);

????//改變字體顏色，大小和在面板上寫入數字

????g.setColor(Color.yellow);

Font font = new?Font("", Font.BOLD, 20);

g.setFont(font);

g.drawString("班級 姓名", 50, 520);

//控制開始和暫停按鈕

????if(isStart){

???? ?????g.drawImage(new?ImageIcon("img/case05/start.png").getImage(), 204, 311, null);

???? ?????g.drawImage(new?ImageIcon("img/case05/icon.jpg").getImage(), 620, 180,null);

????????????for(i=0;i<result.size();i++){

}

?????}

@Override
