一个简单的投票程序

最近有空在学习下Swing方面的知识,就做了点放上来
程序如下:
import java.awt.*;
import java.awt.Event.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.StringTokenizer;

import javax.swing.*;

private JButton com,con,sure,resh,sort;
private Checkbox checkbox[];
private int[] count;
private int totalVote,schoolNumber,max,dis,giveup;
