一个自己写的用来搜索各种文件格式生成txt清单的java工具

写的很久了,没有用线程,比较慢

代码如下

 

//package mp3;

import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JTextArea;
import java.awt.Rectangle;

import java.awt.event.ActionEvent;
import java.util.Vector;
import java.io.File;
import java.io.BufferedWriter;
import java.io.FileOutputStream;
import java.io.*;
import javax.swing.JOptionPane;
import javax.swing.JLabel;
