Best free Java .class viewer? [closed]

Answer 1

JarInspector

Jar Inspector is an easy to use yet powerful jar file editor for Mac OS X. It allows you to effortlessly view, edit and decompile the contents of jar files.

Answer 2

There is a free Java Class Viewer, we can check the Java .class file binary data byte by byte interactively. When clicking each tree node of the class file structure on the left, the corresponding byte data would be highlighted on the right.

Here is an article describes the source code of the Java Class Viewer in detail.

Answer 3

Procyon is a new open source decompiler that already beats JD-GUI in most cases. It's written in Java and comes in a self-contained jar. It is actively developed by StackOverflow's own Mike Strobel.

Answer 4

Eclipse will allow you to view the bytecode for classes, if the source is unavailable (search for 'disassembled bytecodes').

It seems there is also a third-party plugin that uses asm here.

Answer 5

I use cavaj

I've used Decafe Pro (can't find the official site anymore) in the past, but the free version won't let you cut-n-paste.

Both of them are front ends to JAD, so they have the same features and limitations with respect to decompilation capabilities.

Answer 6

i use cavaj, simple to install and gives your very good overview of the class, eclipse style.
