I want the user to input some text ie "2 * 2 / 4 + 1" and the program to do the maths. Is there any open source code to do this or do I need to construct a series of case conditions

you might look at ANTLR vice a series of case conditions

I recently replied a post like this. I that case I suggested the use of BeanShell. It is an open source scripting language and it comes with an expression evaluator. You simply pass an String containg the expression and get the result.

Another option would be to use the new scripting powers of JDK6. Take a look at it.

I hope this helps!
 
I agree. Here's the link: http://aspose.com/file-tools
