我尝试了几种，Procyon似乎最适合我。它正在积极开发中，支持最新版本Java的许多特性。

以下是我尝试过的其他方法:

CFR Promising, but often failed method decompilation. I'll be keeping my eye on this one. Also actively developed with support for the latest Java features. Krakatau Takes a different approach in that it tries to output equivalent Java code instead of trying to reconstruct the original source, which has the potential of making it better for obfuscated code. From my testing it was roughly on par with Procyon, but still nice to have something different. I did have to use the -skip command-line flag so it wouldn't stop on errors. Actively developed, and interestingly enough it's written in Python. JD-GUI Worked, but Procyon's output was much better. Here's a page comparing Procyon output to the original and JD-GUI. JD-GUI is also available as an Eclipse plugin, which didn't work for me at all. Doesn't seem to be open source and development seems sporadic. JAD Worked, but only supports Java 1.4 and below. Also available as an Eclipse plugin. No longer under development.

查看Java源代码，检查一些反编译器。去找贾德。

如果您想查看字节码，只需使用JDK附带的javap即可。

到目前为止列出的JAD链接似乎都是坏的，所以我找到了这个网站。工作得很好(至少对于Linux)!在Ubuntu 11.10上，不知什么原因，我不得不下载静态版本。

大多数Java反编译器都是基于JAD的。这是一个很棒的工具，但不幸的是，它已经有一段时间没有更新了，并且不能很好地处理Java 1.5+类。我还没有看到任何能够正确处理1.5+类的工具。

Soot是较新的Java代码的一个选项。至少它的优点是最近还在维护……

此外，Java反编译器是一个具有独立GUI和Eclipse集成的反编译器。

最后，还没有提到Jdec，尽管它没有其他选项那么完善。

你可以使用一些程序。您将得到实际的Java代码，但有时代码会被混淆，因此方法由一个字母或数字或字母和数字的随机组合命名。
