I want to write a application in application Java regarding solving numerical methods.

What kind of books/tools I Should use for maths reference?

Most of the programming problems can't be solved because you don't know what the exact problem is.
Defining your problem correctly leads you to the right solution.

By now , I am only able to do that in Java. You might have seen some applets solving numerical methods I think Java is one of the best language for doing this kind of stuffs.

I know some of numerical methods but can't find way to convert it into algorithms.Any idea where to begin?(LOL, you must have)

What is Mathlab(tool)? Does Mathlab help to do this kind of stuffs? I know many programmers use calculators and tools to do math works and I wanna know about those tools.

Matlab (like Mathematica) is a standalone program for solving math-related problems. It includes a complete programming language to do that. There's probably a Java API for it, too. It's not cheap, though.

It would be easier to help you if you were more specific about what kinds or algorithms you'd like to implement - differentiation, integration, differential equations, ... ?

You might also have a look at Apache Commons Math, an open source library that has a fair number of helpful classes and algorithms.

Well, I want to implement methods such as interpolation,extrapolation,Integration methods, Numerical ordinary differential equations,B-spline and you whatever you mentioned.

Hey but don't worry I am asking you to implement them for me ,I just need tools to get help.

I know it's not wise to write this kind of program because it's already available as free and more over there is 90% people in the world who hates maths and something like work.

If you guys suggest not to do that then I won't but I need to create some project in Servlet/Jsp environment so pleaze help what topic I should choose to make my employer buzzed.

I think you understand what I mean.

As to apache Library it's great ,thanks my dear friend Ulf dittmer.
