INTRODUCTION ABOUT THE BOOK & AUTHOR
Learning the Java Programming Language is a noble cause, but learning merely the Java Language is not enough in the real world. Java developers have to learn Java EE, a collection of related server-side technologies. To put their JAVA skills to any real use.
But learning Java EE is not enough either. The Jave language along with Java EE may suffice to develop web application for project in the same organization, as means to reusability, but the diverse landscape of Java on the Web is permitted with several frameworks, such as Spring Web MVC, that make development much easier; thus, a Java web developer has to have the knowledge of these web frameworks.
But this is not enough still. In the very first line of this introduction, I mentioned that this book is for a modern Java Web Developer. Modern Java is more than just a language; it is now a fully optimized platform because several other languages such as Groovy and Scala, called the JVM Languages, now run on the Java Virtual Machines (JVM). All such JVM languages, Especially Groovy, have a close association with Java, and you will come across web applications before long where Java and these other JVM languages work in tandem. The most ambitious project will require you to build web applications using these JVM languages.
Chapter 1.3 - Illustrate the user-defined and math functions through sample program | Part 1
The book addresses all the needs of modern, Java web developer. It is designed for beginners up to intermediate developers and the explains the specifics of Java on the Web. For example, this book is perfect for web developers who are aware the technologies like MVC but do not yet understand how to and why they have changed the way web applications built.
The book is also for web developers who want to learn frameworks other than JSF2 (Which is bundled with Java EE). This book covers the four types of frameworks: request based, component-based, rapid and reactive. Among these four types, the book covers five proven web framework: Struts 2, Spring Web MVC, JSF 2, Grails 2, and Play 2.
In addition, this book is for developers who have no experience in the Java, Groovy and Scala programming languages but who learn to create web applications. This book provides the essentials of these three languages in the appendixes.
Instead of simply pronouncing one web framework the best, Learn Java for Web Development shows the strength of the most popular web frameworks by means of a real-world bookstore application. Developing a complete real application necessitates a seamless collaboration of dynamic functionalities, and the code for building such component is contrived and too involved. Instead of focusing on developing such as moving parts, this book confines its attention on leveraging the strengths of each framework #allaboutprogramming62.
