About - Java Architecture and Third Party Libraries

List of Java third-party libraries. This list contains popular open java projects with the projects that I have favored and selected. Some listings have short descriptions and latest versions. Some projects are rated with an A- and above. These are stop projects that are universally used and are constantly updated. They aren't necessarily perfect libraries, even Java is not perfect but these A rated libraries should be familiar to most Java developers.

More opinionated listing based on Awesome Java List: github.com/akullpp/awesome-java and Java Source Net Open Projects
