Java 9 Dependency Injection: Write loosely coupled code with Spring 5 and Guice
by Nilang Patel Krunal PatelCreate clean code with Dependency Injection principlesKey FeaturesUse DI to make your code loosely coupled to manage and test your applications easily on Spring 5 and Google GuiceLearn the best practices and methodologies to implement DIWrite more maintainable Java code by decoupling your objects from their implementationsBook DescriptionDependency Injection (DI) is a design pattern that allows us to remove the hard-coded dependencies and make our application loosely coupled, extendable, and maintainable. We can implement DI to move the dependency resolution from compile-time to runtime. This book will be your one stop guide to write loosely coupled code using the latest features of Java 9 with frameworks such as Spring 5 and Google Guice. We begin by explaining what DI is and teaching you about IoC containers. Then you’ll learn about object compositions and their role in DI. You’ll find out how to build a modular application and learn how to use DI to focus your efforts on the business logic unique to your application and let the framework handle the infrastructure work to put it all together. Moving on, you’ll gain knowledge of Java 9’s new features and modular framework and how DI works in Java 9. Next, we’ll explore Spring and Guice, the popular frameworks for DI. You’ll see how to define injection keys and configure them at the framework-specific level. After that, you’ll find out about the different types of scopes available in both popular frameworks. You’ll see how to manage dependency of cross-cutting concerns while writing applications through aspect-oriented programming.Towards the end, you’ll learn to integrate any third-party library in your DI-enabled application and explore common pitfalls and recommendations to build a solid application with the help of best practices, patterns, and anti-patterns in DI. What you will learnUnderstand the benefits of DI and fo from a tightly coupled design to a cleaner design organized around dependencies See Java 9’s new features and modular frameworkSet up Guice and Spring in an application so that it can be used for DIWrite integration tests for DI applicationsUse scopes to handle complex application scenariosIntegrate any third-party library in your DI-enabled applicationImplement Aspect-Oriented Programming to handle common cross-cutting concerns such as logging, authentication, and transactions Understand IoC patterns and anti-patterns in DI Who this book is forThis book is for Java developers who would like to implement DI in their application.

Java 9 Modularity Revealed
by Alexandru JecanDevelop modular applications using the Java Platform Module System, the single most anticipated feature in Java 9. You will improve maintainability and performance of your Java applications by deploying only modules that are needed and encapsulating their implementation details. Until now Java has been monolithic. Using any one part of Java has meant incorporating the entirety of the runtime environment, an approach ill-suited to the increasing number of IoT devices such as fitness monitors, kitchen appliances, toys and games, and so forth. This book shows a new way, to make Java scale from the smallest of footprints in the smallest of devices through desktop PCs and on up to server platforms. With Java 9 Modularity Revealed you will learn to make your projects more reliable and scalable than ever using the most important feature in Java 9—The Java Platform Module System, known more commonly as Project Jigsaw. You will learn how to avoid one of the major pain points of Java programming, that of conflicting class names from different modules, or packages. You will learn to create custom run-time images that represent a minimal and more compact JRE containing only those modules that you need. You will further learn to migrate existing Java applications to modular ones using different approaches and tools. The end result is a new ability to plug together different modules without fear of namespace and other conflicts, and you can deploy to everything from small devices to large servers. This book provides code examples and explanations.What You'll Learn Build Java applications using the new modular system introduced in Java 9 Create your own JRE consisting only of the modules that you require Adapt your testing techniques toward modular applicationslare your dependencies on other modules Enable modules to export only specific packages Migrate existing Java applications to modular ones Improve maintainability and performance of Java applicationsWho This Book Is ForExperienced Java programmers wanting to keep up and become informed on the new modularity support in Java 9

Java Bibliography
by Safari Content TeamIn the early 1990s, a team of developers at Sun Microsystems, led by James Gosling, designed and implemented a new computer language: Java. The language was object oriented, was compiled into an intermediate form called Java Bytecode, and those bytecode instructions were run on a virtual machine called the Java VM. Java, at the time, was a revolution in itself. It quickly became the language of a new generation of software developers who were writing small applications for the web, server applications for the enterprise, and even desktop applications. Today many new languages compile into Java bytecode and are run on top of the Java VM such as Scala, Groovy and Clojure, as well as variants of Python, Ruby, and Erlang. Java is also the language used to write programs for many of the world's mobile devices, including Android. If you're interested in Android development, there is also a bibliography specific to that platform. Oracle acquired Sun Microsystems in January of 2010 and became the owner of the Java technology. So far, this has not changed how Java has been positioned in the market. Open source software projects have used Java extensively to create some of the world's most popular software libraries. These libraries have likely been one of the driving forces behind the creation of many of the JVM based language ports. Of course, people have to learn about how to use these libraries and languages, so the books written about Java are also varied in nature. There are a great many excellent learning reference books, class library reference books, and books on enterprise and web development. There are books that cover the Java Virtual Machine based languages mentioned earlier. The Spring Framework is a highly popular, open source, modular, infinitely configurable framework written in Java that is also covered well by technical book writers. Many games are written in Java, and we've included a few books on Game programming. If you are writing web services, you'll want to read about Service Oriented Architecture as well as storing and retrieving data using one of the many Java persistence frameworks. This bibliography covers the entire Java language, spanning from introductory to advanced topics. We hope you enjoy them and use them to your
Java By Comparison
by Simon Harrer Jörg Lenhard Linus DietzWrite code that's clean, concise, and to the point: code that others will read with pleasure and reuse. Comparing your code to that of expert programmers is a great way to improve your coding skills. Get hands-on advice to level up your coding style through small and understandable examples that compare flawed code to an improved solution. Discover handy tips and tricks, as well as common bugs an experienced Java programmer needs to know. Make your way from a Java novice to a master craftsman. This book is a useful companion for anyone learning to write clean Java code. The authors introduce you to the fundamentals of becoming a software craftsman, by comparing pieces of problematic code with an improved version, to help you to develop a sense for clean code. This unique before-and-after approach teaches you to create clean Java code. Learn to keep your booleans in check, dodge formatting bugs, get rid of magic numbers, and use the right style of iteration. Write informative comments when needed, but avoid them when they are not. Improve the understandability of your code for others by following conventions and naming your objects accurately. Make your programs more robust with intelligent exception handling and learn to assert that everything works as expected using JUnit5 as your testing framework. Impress your peers with an elegant functional programming style and clear-cut object-oriented class design. Writing excellent code isn't just about implementing the functionality. It's about the small important details that make your code more readable, maintainable, flexible, robust, and faster. Java by Comparison teaches you to spot these details and trains you to become a better programmer. What You Need: You need a Java 8 compiler, a text editor, and a fresh mind.That's it.
