我可以使用什么程序来反编译类文件?我真的会得到Java代码,还是仅仅是JVM汇编代码?
关于这个网站上的Java性能问题,我经常看到一些人的回答,他们“反编译”了Java类文件,以了解编译器如何优化某些东西。

使用AndroChef Java反编译器,您可以反编译apk, dex, jar和Java类文件。这很简单。AndroChef JD基于FernFlower。你可以在10次免费使用中评估它。
AndroChef支持Java语言特性,如泛型、枚举和注释。根据一些研究,AndroChef Java Decompiler能够反编译98.04%的由传统Java编译器生成的Java应用程序——一个非常高的回收率。它是一个简单但功能强大的工具,允许您将Java和Dalvik字节码(DEX, APK)反编译为可读的Java源代码。

JD-GUI真的很好。您只需打开一个JAR文件,然后浏览代码 你正在开发一个IDE。好东西。
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.
Procyon包含一个反编译器。它是自由/开源软件。
在IntelliJ IDEA平台上,可以使用Java反编译器IntelliJ Plugin。它允许您在调试过程中显示所有Java源代码,即使您没有全部Java源代码。它基于著名的工具JD-GUI。
JAD不为我工作(Ubuntu 11.10问题),所以我已经前进和浸泡在JODO。至少它有Open Java源代码,并且能够正确地反编译我的.class。
我建议先查看“分支/通用”分支。树干不稳。
