Certainly! Here's a detailed review and recommendation of the Coursera course on Java 9: --- **Course Review and Recommendation: Exploring the New Features of Java 9** If you're a Java developer eager to stay current with the latest advancements or someone transitioning from another programming language looking to enhance your career prospects, this Coursera course on Java 9 is an excellent choice. **Course Content and Structure** This course is thoughtfully designed to provide a deep understanding of the new features in Java 9, rather than just skimming through the surface. It strikes a perfect balance by offering enough detail to grasp each feature's significance while maintaining clarity with relevant examples. The instructor, Dr. Frank Mitropoulos, brings over 23 years of software development and teaching experience, ensuring the material is approachable and well-explained. **Key Topics Covered** - **Java Shell:** One of the standout features, the Java Shell (JShell) simplifies learning, experimenting, and exploring Java code snippets. The course emphasizes its use in educational contexts as well as practical development, encouraging learners to integrate it into their daily coding routines. - **Java Platform Module System:** Perhaps the most discussed feature, this system introduces a modular architecture to Java. The course walk-through includes the motivation behind this change, detailed explanations, and a hands-on example where a JokeServer application transitions from non-modular to fully modular with a JavaFX front end. This practical approach helps learners appreciate the system's power and utility. - **Process API Enhancements:** The course covers updates to the Process API, showcasing how developers can now manage native processes seamlessly within Java, eliminating the need for complex JNI code or hacks. Live demonstrations make these concepts tangible and demonstrate their real-world applicability. **Pros** - Clear, in-depth explanation of Java 9's new features - Practical examples that reinforce understanding - Experienced instructor with a teaching-focused approach - Well-structured content that guides learners from motivation to implementation - Covers migration issues and transitional considerations **Cons** - Designed primarily for those with some Java background, so absolute beginners might find certain topics challenging without prior knowledge - It doesn't cover all aspects of Java 9 but focuses on the most impactful features **Final Recommendation** This course is highly recommended for Java developers who want to upgrade their skills to Java 9 efficiently and effectively. The combination of thorough explanations, practical examples, and best practices makes it an invaluable resource. Whether you're updating your existing projects or preparing for future developments, you'll find this course offers the insights and hands-on experience needed to leverage Java 9's powerful new features confidently. **Get started today** and be at the forefront of Java development! ---

Overview

Do you know some Java, but worry that with the recent release of Java 9, your skills are now outdated? Maybe you are a programmer in another language, but want to improve your career prospects by learning about Java 9? Perhaps you know Java 8 well, and want to find out about the new features in Java 9 so you can put them to use as quickly as possible? Whatever the reason, if you want to find out about the new features in Java that are relevant to the majority of Java developers, then this course is for you. The goal of the course was not to simply go quickly through all the new features in Java 9 at a very high-level. Nor was the goal to get into such detail that we forget about the feature we are studying. Instead, the course was designed to help you really understand these new features. So, we'll look at what motivated the changes in Java 9 so we can better understand why there are needed and what issues they address.Then simple, but relevant examples are provided to demonstrate each feature.Your instructor in this course is Frank Mitropoulos Ph.D, a university professor with over 23 years of software development teaching experience. What are some of the new features in Java 9? Among the many new features in Java 9 are the Java Shell, The Java Platform Module System, and updates to the Process API.In this course we'll look at the Java Shell in detail. We think you will love the Java shell! It makes learning Java, exploring APIs, and experimenting with Java code so much easier and very productive. Once you start using it, we think you will go back to it over and over again when you have to write small snippets of code and especially when you are learning a new concept.The Java Platform Module System is probably the feature that most developers have heard about when they think about Java 9. The Java 9 Platform Module System allows Java to move forward by modularizing the JDK as well as adding modules as first class citizens to Java. The module system is actually quite intuitive and we think you will understand it and appreciate its impact straight away.In this course we explain the motivation and goals for the module system and then we look at every detail. Along the way we create a modular JokeServer application that we take from not using modules at all, all the way through being completely modularized and having a JavaFX front end.Finally, we discuss some of the issues you may have when migrating existing non-modular code in Java 9 and we walk through a simple example. Another exciting addition to Java 9 are the updates to the Process API. The Process API allows developers to work with native processes directly in Java code.No more hacky code and no more Java Native Interface code is needed to do things that were previously impossible to do directly in Java. In this course we look at the main use-cases where the Process API can be used and show live code examples right in the Java shell. You won't believe how easy we can now work with processes on any OS.That's just an example of some of the content of What's New in Java 9.
