Expression Evaluator for Java
Expr4j is a simple Java library to evaluate mathematical expressions. The entire library is written in core Java without any external dependencies.
The expressions are evaluated using Dijkstra's Shunting Yard algorithm. Multiple robust implementations of the algorithm are provided and you can choose which implementation to use depending on your preference.
Tested
Expr4j is rigorously tested with a large number of unit test cases to ensure quality and stability.
Also if you come across any bugs, you can raise an issue on Github.
Documented
The Expr4j API is well documented in standard Java Doc format.
You can explore the API documentation to obtain information about classes and methods.
Open Source
Expr4j is an open source library licensed under Apache License, Version 2.
This gives you the freedom to use Expr4j in commercial and non-commercial applications.
