This project gives a mathematical parser for converting a simple string expression into a result which can be managed for using in other calculations, all in Java.
Using a couple lines of code, you'll be able to parse complex arithmetic expressions efficiently. This library is powered by Dijkstra's Shuting-yard algorithm.
The library has no dependencies with other external libraries.
