文件管理模拟实验

文件管理模拟实验

实验内容：

（1）编写程序，实现文件和目录的复制、删除、移动、重命名等操作；（2）编写程序，读取并显示文件的属性，修改文件的属性；

一、流程图：

二、源代码：

Main.java

package com.file_operate;

b2 = new JButton("删除");

b3 = new JButton("另存为");

b4 = new JButton("重命名");

b5 = new JButton("查看文件属性");

area = new JTextArea();

this.init();

}

b5.addActionListener(this);

}

public void showMe()

{

area.append("该文件名称为：" + file.getName() + "\n");

try
