A Deep Dive into The Java Platform Module System (JPMS)
Learn the tools for creating modular, space-optimized, and extensible software in Java.
Course Objective
Need for Modular Software
As software engineers, our goal is to write code that is easy to understand, maintain, extensible, and secure. These goals are even more important when building large, complex software comprising several inter-dependent components. Fundamental design principles like Information Hiding helped accomplish many of these goals. However, prior to Java 9, some of these goals could still be compromised due to the limitations in the underlying features such as packages & access modifiers, which could not always provide the needed encapsulation. Moreover, there were other configuration issues due to inherent limitations in JAR files and the ever-growing size of JDK. To address all the issues, another layer of abstraction was needed; and in Java 9, this abstraction was provided in the form of modules through The Java Platform Module System (JPMS).
Course Overview
Creating Modular Software
This course will give you an in-depth understanding of JPMS and how it enables creating strongly encapsulated, modular software. We will start off by reviewing the problems that JPMS addresses thus clearly understanding the purpose it serves. We then understand the anatomy of a module and how to create it from both command line as well as from Eclipse. We will look at how modular and non-modular code can interoperate. We will next learn how to create custom runtime images (JREs) or in other words smaller distributables. This is one of the most exciting features of JPMS and something every developer must learn. Finally, we will look at how we can create services, a crucial feature of modular programming. We will learn how services can be added without redeploying our application.
Every concept is very clearly explained with well thought out & realistic examples, nice illustrations and perfect demonstrations. With over 5 hours of high-quality video lectures, the course is self-paced with life-time access. You get a certificate upon course completion.
