Welcome to the Ranch
I am afraid you have posted in the forum where we discuss Ranch problems, so I shall move your discussion.
You will get help quicker if we know what the question is; you would do well to use the "edit" button to change your thread title.
You will have to work out what the algorithm is, because we don't hand out code. Work the algorithm out, and write down with pencil and paper, and a large eraser, exactly how you wold solve it by hand. When you have that, you will know how to do it on screen.
And we never use the word "urgent".

This is not really a Java question, it is more of a scientific programming question.

You will need to start by writing down the equation for the Entropy balance for your system.

If the balance depends on time, or other state derivatives, you will probably need a initial value ode solver. They are not hard to write, just substitute a small delta t for dt in the equations. Or, do a google on initial value ode java. Runge Kutta is a typical initial value ode solution algorithm.

If the balance does not depend on time, or other state derivatives, then you have to just solve the equation for Entropy. And then program the resulting equation.

Here is a link to a java entropy solution
Java Entropy Solution
And, here is a link that defines entropy, to help you write down the equations for your system. Entropy Equations

ok sir.. here after i wont use the word urgent...
i'l try to do my own work with that algorithm, also i searched in google..
I didnt get any information regarding that.. thats why posted as forum..
I need Entropy Variation algorithm coding(in JAVA) for DDOS attack..

//NOTE//
My Base Paper Title: "Traceback of DDOS attacks using Entropy Variations"


Thank you..

I misunderstood the word Entropy. Good luck with your search. Sounds like an interesting, and important, topic.

Welcome to the Ranch
I do not know whether that code will be available; you might find something useful if you google for it.
 
Don't get me started about those stupid light bulbs.
