Java语言实现简单FTP软件 FTP软件主界面（4）

首先看一下FTP软件的整体代码框架，具体内容如下

1、首先介绍程序的主入口FTPMain.java，采用了一个漂亮的外观风格

package com.oyp.ftp;

import java.util.logging.Level;

import java.util.logging.Logger;

import javax.swing.UIManager;

import com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel;

public class FTPMain {

/**

* 本应用的程序入口

public static void main(String args[]) {

//导致 runnable 的 run 方法在 EventQueue 的指派线程上被调用。

java.awt.EventQueue.invokeLater(new Runnable() {

public void run() {

try {

//使用 LookAndFeel 对象设置当前的默认外观。

UIManager.setLookAndFeel(new NimbusLookAndFeel());//设置一个非常漂亮的外观

// UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

FTPClientFrame client_Frame = new FTPClientFrame();

client_Frame.setVisible(true);

} catch (Exception ex) {

Logger.getLogger(FTPClientFrame.class.getName()).log(

Level.SEVERE, null, ex);

}

});

}

2、介绍界面的主程序代码FTPClientFrame.java
