Hello there,

I would like to ask you, if exist some way how to convert string "1+2+3" to math equation? Exist for this purpose some function or method in Java?

Thanks for hints.

I disagree that this is a dupe; that one wants the solution to the equation, but this one just wants it to become an equation object of some kind. — Pops, Apr 14 '11 at 20:23

This would necessarily depend on the implementation of the Equation class you're using. Check its API.

It's not part of the standard API.

But I implemented it in my project, you can have a look here. https://github.com/MarkyVasconcelos/Towel/wiki/Expression

Thank for hint, Marcos. But I am a bit confused - can you help me, please, where is saved the method called "Expression"? Thanks.. – user1946705 Apr 14 '11 at 21:26
By downloading the towel jar and adding into class-path, there's a lot of useful classes there. – Marcos Vasconcelos Apr 14 '11 at 21:35
