Kotlin – The Game Changer

Enterprises typically develop their applications or microservices based on Java. Java is the first choice of language for development because it is robust, safe, and backward compatible. Java's platform independence makes it suitable for developing web services and enterprise applications. Having said that, however, have we ever considered whether there might be a better way to write code, one that makes it easy not only to develop an application, but also to maintain it over a period of time?

With its elegant syntax and numerous features, Kotlin makes it much easier to work with. Writing code with Kotlin is much simpler. We can develop complex applications quickly and maintain them easily:

The following topics will be covered in this chapter:

What makes Kotlin stand out among other JVM-based languages
A comparison with Java
How to configure...

Key benefits

An in-depth guide updated with all the latest features of Kotlin 1.2 and Java EE 8

Description

Kotlin was developed with a view to solving programmers’ difficulties and operational challenges. This book guides you in making Kotlin and Java EE work in unison to build enterprise-grade applications. Together, they can be used to create services of any size with just a few lines of code and let you focus on the business logic. Kotlin for Enterprise Applications using Java EE begins with a brief tour of Kotlin and helps you understand what makes it a popular and reasonable choice of programming language for application development, followed by its incorporation in the Java EE platform. We will then learn how to build applications using the Java Persistence API (JPA) and Enterprise JavaBeans (EJB), as well as develop RESTful web services and MicroServices. As we work our way through the chapters, we’ll use various performance improvement and monitoring tools for your application and see how they optimize real-world applications. At each step along the way, we will see how easy it is to develop enterprise applications in Kotlin. By the end of this book, we will have learned design patterns and how to implement them using Kotlin.
