This chapter introduces Project Jigsaw. It describes what Project Jigsaw is all about, shows some problems encountered in the past in Java, and discusses the Java Enhancement Proposals that constitute Project Jigsaw. It explains the goals of Project Jigsaw so that we can get a grasp of the reasons that made the JCP team decide to introduce a new module system for the Java platform. It also goes over concepts like strong encapsulation and reliable configuration.
