class file viewer

[vivien siu]

Hi guys, is there any software/freeware to view .class files?

[Ulf Dittmer]

The simplest option is to use the "javap" command line tool that comes with the JDK.

If you're looking for a GUI, check out jclasslib.

[Jesper de Jong]

Well, what exactly do you mean with "viewing .class files"?

There are a number of Java decompilers available, which can translate the byte code in a class file back to source code (or something that looks like the original source code).

For example: DJ Java Decompiler, JAD. Search for "Java decompiler" on Google for more.

yup I was looking for a java decompiler software, thanks!

Hello,

Some people obfuscate the code, so dont believe the code generated by the decompiler as such. Just have some hands on work ....

[Peter Chase]

And remember that it is illegal and/or immoral to decompile a third-party class file, to try to replicate, crack or alter it, against the wishes and/or licence of the third party.

It's ok Peter, I'm just looking at some old codes done by my colleagues. There are only .class files available in the server.
