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);
    }
   }
  });
 }
}
