Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible.  As for Maven it's a build automation tool used primarily for Java projects. Maven addresses two aspects of building software 
1-how software is built.
2- its dependencies.
Unlike earlier tools like Apache Ant, it uses conventions for the build procedure. Only exceptions need to be specified. An XML file describes the software project being built, its dependencies on other external modules and components, the build order, directories, and required plug-ins.
