This allows us to incorporate Kotlin into existing Android projects and use Kotlin easily together with Java (if we want to).

Kotlin classes can also be directly instantiated and transparently referenced from Java code without any special semantics and vice versa. Many Java libraries even Kotlin-specific versions that allow more idiomatic usage with Kotlin. The existing ecosystem of Java libraries and frameworks works with Kotlin without any performance penalties. Interoperability: Kotlin is designed to seamlessly work side by side with Java (cross-language project).As a result, the code is also easier to read and understand (expressive). We need less code to achieve common tasks and thus the amount of boilerplate code is greatly reduced, even comparing Kotlin to Java 8. Conciseness: Most of the Java verbosity was eliminated.For example, it can distinguish mutable (read-write) and immutable (read-only) collections by providing convenient interfaces (under the hood collections are still mutable). Kotlin offers a convenient way to work with immutable data. Easy debugging: Bugs can be detected much faster during the development phase, instead of crashing the application after it is released and thus damaging the user experience.We can describe Kotlin as a safe, expressive, concise, versatile, and tool-friendly language that has great interoperability with Java and JavaScript. It has a very active community and Kotlin adoption on the Android platform is already growing quickly. Official Kotlin support for the Android platform was announced by Google in 2017, but the Kotlin language has been here for some time. Kotlin takes application development to a whole new level by improving code quality and safety and boosting developer performance. When working with Kotlin, we can really feel that this is a mature and well-designed language. Kotlin tries hard to not repeat the mistakes from other languages and take advantage of their most useful features. Deep analysis of other programming languages has been done. Kotlin was designed by JetBrains professionals, based on analysis of both developers experiences, best usage guidelines (most important are clean code and effective Java), and data about this language's usage. Kotlin is a language inspired by Swift, Scala, Groovy, C#, and many other languages. Kotlin is a modern, statically typed, Android-compatible language that fixes many Java problems, such as null pointer exceptions or excessive code verbosity. You will be ready to start your own adventure with Android development with Kotlin. You will get to know and understand most important Kotlin features, and how they can be used.
#Teamcity kotlin how to#
Through the book, you will learn how to use Kotlin for Android development. You will learn how certain tasks can be achieved in simpler ways thanks to Kotlin. The last module presents features that are not present in Java. You will learn how Kotlin brings many improvements to the table by improving common Java concepts and decreasing code verbosity.
The next module dives deeper into the building blocks of Kotlin, such as functions, classes, and function types. This module will lay a firm foundation for the rest of the chapters so you are able to read and understand most of the Kotlin code. Each module present features in different levels of advancement. The book is divided in three modules that show the power of Kotlin and teach you how to use it properly. It also shows all the benefits, improvements and new possibilities provided by this language. It demonstrates how common examples that are typical for Android development, can be simplified using Kotlin.
This book discusses Kotlin features in context of Android development. Kotlin is a language that helps developers build amazing Android applications easily and effectively. It has become crucial to find improved ways of writing code. Nowadays, improved application development does not just mean building better performing applications.
