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
