Java disassembler

Hi
I'd like to disassemble a very simple Java class which works as a fuel consumption manager on my mobile. Is there a way to do it?
Freeware or shareware options are prefered.
Please advise

Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

So, it is looking like a second piece of the puzzel. The web site I downloaded the .jar file from, also offers a .jad download. Is it what I want? (The source code?)

JAD is java decompiler

Hi,
You give the class files to the JAD program and it makes java code from them.

But you may have in mind that the generated java code is not very readable especially for unaccustomed person.

Yes I konw. I did that, and get a .java file in the end. However, in the middle of my learning curve here, I understood there is a .jad format too. Does it help me about understanding the source code in any way? Or what is it useful for?

You don't need it, at least for that purpose.
the .jad files contains description for J2ME jar files. It is used for installing applications on mobile phones for example.
You can look at the following page for a brief info:
