How do you know what are the variables within the assembly code?thanks for the help.
n.b
If you also show me some piece of code. thanks
Assembly has registers which can be used like variables but with a few limitations (size etc.). Assembly will be different based upon the type of processor you are writing it for. Check out the wikipedia article for x86.

I would like to know how to use java agent and how to install java agent.
I handle for the first time java agent.
So they are not familiar.
So please explain in detail.
Presuming that you actually mean agents as in instrumentation, check this tutorial:
http://www.javabeat.net/introduction-to-java-agents/
it will give you a quick start in writing your first agents and set up everything you need to get started.
Just on a side note: if you want specific, detailed answers, ask specific, detailed questions.

Is there a program, or a native feature of Eclipse that allows for running a class in steps, each step being detailed (value of containers at that step, highlighting the line of code that is being executed at that step, etc).
You can try Jive debugger. This was developed by my university.
