Kotlin in Action MEAP V11 Pdf Book Description:

Thanks for purchasing the MEAP for Kotlin in Action ! We’re looking forward to introducing you to Kotlin, which is a new programming language that is a pragmatic, safe, concise, and interoperable alternative to Java. With Kotlin, you can implement your projects with less code, a higher level of abstraction, and fewer annoyances. We assume that you’re already familiar with Java, either as a server-side developer or as an Android application developer. Switching from Java to Kotlin is a smooth process that does not involve a steep learning curve, and there are many tools that can help. We expect that it won’t take you long to become productive with the language. One of the strong points of Kotlin is its strong interoperability with Java. If you want to try Kotlin for yourself, you can do this in a new project, but you also have an option of introducing it into your existing Java codebase. You can also easily try features of the language in an interactive console or an online playground. The book consists of three parts. The first part will teach you the basic syntax of the language.

The second part will focus on features that allow you to build reusable abstractions, higher-level functions, libraries, and even entire domain specific languages. Finally, the third part will focus on details of applying Kotlin in real-world projects, such as build system integration, Android support and concurrent programming. Both of us have been part of the team working on Kotlin for the past five years, so you can be confident that you’re receiving authoritative information straight from the source. And of course, as Kotlin evolves towards 1.0 and beyond that, we’ll ensure that the information in the MEAP book always corresponds to the current state of the language.First, what is Kotlin all about? It’s a new programming language targeting the Java platform. Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. It can be used almost everywhere Java is used today for server-side development, Android apps, and much more. Kotlin works great with all existing Java libraries and frameworks and runs with the same level of performance as Java. Let’s start with a small example to demonstrate what Kotlin looks like. This example defines a Person class, creates a collection of people, finds the oldest one, and prints the result. Even in this small piece of code, you can see many interesting features of Kotlin; we’ve highlighted some of them so you can easily find them later in the book. The code is explained briefly, but please don’t worry if something isn’t clear right away. We’ll discuss everything in detail later.
