SimplexSolver is an easy-to-use, object-oriented method of solving linear programming problems. While numerous other libraries are available that run linear optimization problems, SimplexSolver is the first written in Java with a commercially-friendly license. Google announced of Open Sourceing the code that runs the newly released Google Spreadsheets Solve Feature and made it a part of Apache Commons Math 2.0. Looking at the LP problem and Java code side-by-side, we can see how easy it is to describe the problem in the Apache Commons Math API.
