基于myecilpse软件制作的欢乐摇奖器

源代码：

1.创建窗体的代码：

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.创建面板的代码：

package lottery;

//定义初始量

//定义集合

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

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

private int i;

//读取txt文件

count++;

id++;

            }

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public void paint(Graphics g){

super.paint(g);

//读写图片

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

    //改变字体颜色，大小和在面板上写入数字

    g.setColor(Color.yellow);

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

g.setFont(font);

g.drawString("班级 姓名", 50, 520);

//控制开始和暂停按钮

    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);

            g.setColor(Color.blue);

            g.setFont(new Font("",Font.BOLD,20));

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

         g.drawString(result.get(i), 580, 130+i*22);

}

     }
