Key Features Learn Kotlin by drawing direct comparisons to core Java concepts Understand null safety, coroutines, extension functions, and DSLs through practical examples Use Kotlin confidently in backend, Android, and cross-platform development Purchase of the print or Kindle book includes a free PDF eBook Book Description This book is a hands-on programming guide for Java developers who want to gain practical, production-ready knowledge of Kotlin. Whether you’re maintaining Java systems or adopting Kotlin for Android, backend, or cross-platform projects, it will help you bridge the gap by building on your existing understanding of Java’s syntax and design principles. You’ll begin by learning why Kotlin was created and how it improves on Java – exploring types, expressions, control flow, and null handling while mapping each concept to familiar Java constructs. Each topic is introduced with clear purpose, showing how Kotlin’s concise syntax, safety features, and expressive APIs lead to cleaner, more maintainable code. As you progress, you’ll master object-oriented and functional programming, extension functions, smart casting, and interoperability with Java. The second half of the book dives into generics, data and sealed classes, coroutines for concurrency, and DSL design – demonstrating when and why to use these features to build scalable, elegant solutions. By the end, you’ll not only write idiomatic Kotlin but also understand the reasoning behind its design, enabling you to craft modern, reliable applications with confidence. What you will learn Write Kotlin programs using variables, functions, and control flow Model real-world data with classes, properties, and constructors Handle missing data safely with nullable types and safe calls Simplify logic using lambdas and extension functions Work with Kotlin collections and sequences to process data efficiently Use Kotlin with Java, Gradle, and Maven for seamless project builds Write non-blocking code using coroutines and Async flows Create custom DSL for your projects Who this book is for This book is for software developers who are proficient in Java and want to learn Kotlin for professional application development.

It takes a week to travel the 8,000 miles overland from Java to Kotlin. If you're an experienced Java developer who has tried the Kotlin language, you were probably productive in about the same time. You'll have found that they do things differently in Kotlin, though. Nullability is important, collections are different, and classes are final by default. Kotlin is more functional, but what does that mean, and how should it change the way that you program? And what about all that Java code that you still have to support? Your tour guides Duncan and Nat first made the trip in 2015, and they've since helped many teams and individuals follow in their footsteps. Travel with them as they break the route down into legs like Optional to Nullable, Beans to Values, and Open to Sealed Classes. Each explains a key concept and then shows how to refactor production Java to idiomatic Kotlin, gradually and safely, while maintaining interoperability. The resulting code is simpler, more expressive, and easier to change. By the end of the journey, you'll be confident in refactoring Java to Kotlin, writing Kotlin from scratch, and managing a mixed language codebase as it evolves over time.

4+ Hours of Video Instruction Google officially announced Kotlin as a first-class language for Android development, which makes it the only language apart from Java officially supported on the platform. Adoption of Kotlin is growing steadily since its release of version 1.0 in 2016. With companies like Netflix, Uber, Pinterest, and Trello actively using it, we can expect the adoption of Kotlin to grow significantly in the near future. There is very little pointed and in-depth coverage from developers for developers at this stage. With Kotlin from the Ground Up LiveLessons , we attempt to fulfill the requirements of developers who want to get acquainted with Kotlin and its features. Kotlin was designed to be an industrial-strength, object-oriented language-and a "better language" than Java-but still be fully interoperable with Java code, allowing companies to make a gradual migration from Java to Kotlin. Description Kotlin is one of the most exciting new languages to come along in some time. Built with pragmatism and interoperability in mind, Kotlin is one of the easier languages to transition to for many Java developers. However, many who come to Kotlin are not coming from a Java background at all. In this course, we take a look at Kotlin from the ground up and cover the topics necessary for a solid understanding of Kotlin. In this course, we cover the basics of the language as well as delve in to some of the trickier aspects. We address topics such as builds and testing, generics, and extension functions. We even take a look at how Kotlin can help you write your own DSLs. We build up a tool set to help make you the most productive and happy Kotlin developer you can be. Skill Level Beginning to Intermediate What You Will Learn Write and build your first Kotlin program Leverage existing Java libraries seamlessly in your Kotlin code Create libraries in Kotlin that are accessible to Java developers Build basic DSLs to ease development pains in whatever domain you find yourself Who Should Take This Course Java developers who want to explore Kotlin Developers with no Java background but a desire to learn Course Requirements While there are a number of comparisons to Java throughout the material, Java knowledge or expertise is not required. These comparisons are largely used to highlight where Kotlin diverges from Java for the sake of those in the audience coming to Kotlin from Java.

* A book containing examples and explanations of examples* For beginners, there is a special section for professionals* It brings you more and more understandingAt the I / O 2017 conference, Google announced its support for the Kotlin programming language for Android application development and will be included in the new version of Android Studio 3.0, and no additional installation settings are required.Java and Kotlin are among the most popular programming languages used by Google to develop Android applications. Since 2011, Kotlin has emerged as a new language for Java Virtual Machine, developed by a team of St. Petersburg programmers called Jet Brains.The team launched the first stable version of Kotlin last year Kotlin 1.0, and since then they released the new update kotlin 1.1 in early March, and soon began to talk about the world, and also loved by the software community! The team receives and relies on language suggestions during development, as well as Open Source on Github, and of course as a programmer this is great for you To compare now between them and Java, of course we must first make clear that Kotlin is not here to replace Java at all, any code written in Java will work with Kotlin and vice versa!Kotlin requires fewer lines of codeLess by about 20%. As we know the age of the language of Java 22 years, created by Oracle to be compatible with the above, which means that each new version to support features exist in the versions that preceded it, so with each update becomes more difficult to include new features, It is written every time.In contrast, Kotlin was built from scratch, meaning the absence of the structure of the layers stacked on top of each other.Less collapses occur with KotlinJTM's JTM has fewer problems compared to the so-called "one billion dollar mistake" - any problem with NullPointerExeption - that can be avoided here. This problem exists in all programming languages, but different ways to deal with it. For example, in Java you have to manually check if the link is null or not, and if you make a mistake, surprise the program has collapsed! In Kotlin, all object objects are set to Null as well as automatic verification of the NullPointer exception, to ensure that the code works properly without it.Kotlin saves you a lot of time!Fewer codes guarantee fewer software errors, and therefore less time spent on coding. Typically, any software development team calculates the total cost of the project according to the number of encoding hours.Interop interoperabilityYou might wonder how this will affect the code you wrote? Do not worry, as I mentioned earlier, Kotlin is not here to replace Java, but they are perfectly compatible. Which means that you can write part of the code using Java and the rest using a Kotlin and will work together without problems.In addition, there is a tool in Android Studio that translates java into Kotlin, and it works very well, giving you a glimpse of what the Kotlin Java method looks like.
