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); 
    } 
   } 
  }); 
 } 
}
