反编译问题。（有挑战性呀，送200分，分2次给分）------第二贴

Question

哪位大侠能把下面的java程序反编译出来。送200分，分2次给分 
程序下载地址 
http://wqywqy.googlepages.com/waveinterference.jar

Answer 1

我想反编译下WINDOWS系统
谢谢哪位同志帮下忙吧....
我另外出帖子给你加分哦~~~~
别想拿linux来忽悠我哦

Answer 2

其实吧java类反编译很简单，jdk已经有这个命令javap xx.class

Answer 3

我把 jar文件解压，随便找出了一个类BasicService.class  反编译
得出以下结果：
Compiled from "BasicService.java"public interface javax.jnlp.BasicService{public abstract java.net.URL getCodeBase();public abstract boolean isOffline();public abstract boolean isWebBrowserSupported();public abstract boolean showDocument(java.net.URL);}

Answer 4

用jad吧，直接把jar包放到eclipse下，然后打开里里面的类，会自动反编译的．

Answer 5

用Eclipse安装插件Jode Decompiler,安装方法网上很多.
把要waveinterference.jar在java构建路径下引入.
然后就可以像打开类一样打开*.class文件了.下面是其中的一个类/*jode*/
/* BarrierSideView - Decompiled by JODE
