"Kotlin is a statically typed language whose syntax is more expressive and concise. Kotlin has been adopted by Google as a first-class language for developing Android apps. Since then, Kotlin has gained a huge popularity worldwide among developers due to its highly appreciable features, which we will cover in this course. The course starts by showing you how to set up the Kotlin environment and install Intellij IDEA to write Kotlin code. After that, the course dives into the Kotlin basics and fundamentals such as variables, data types, string templates, expressions, null values, and loops. Moving on, you'll learn how to write functions in Kotlin. You'll explore Kotlin as an Object-Oriented Language by exploring interfaces and various Kotlin classes . Next you'll dive into Functional programming in Kotlin using Lambdas and higher-order functions . Finally, you'll explore the collection framework and perform operations such as filtering and sorting using Predicates and FlatMaps in Kotlin. By the end of the course, you'll be able to build your own robust program in Kotlin."--Resource description page.

Kotlin is the new lovechild of the JVM developers' world.Google promoted Kotlin as a first class language on its Java-based Android platform back in May. Since then, the whole development world has been wondering: what is this language? Kotlin has been around for a few years and has been running on production systems, after the languages 1.0 release in February 2016, for a year or so. The language has received a lot of praise and loving words from the developer community. It is a breath of fresh air, a good upgrade to systems running older versions of Java, and still somehow an old dog in a familiar playing field.What is Kotlin? What does it bring that the JVM doesn't already have?Kotlin vs. JavaThere are a few approaches we can take when introducing Kotlin. We can discuss it through Java, the language Kotlin needs to be based on due to its JVM runtime, or we can do it through Scala, the language Kotlin is heavily influenced by. There is no doubt that Kotlin is better than Java. It is much safer and more concise. It provides you with a bunch of additions to your standard Java language and enhances a few bits and pieces that Java developers have grown to dislike. Additions include things like null safety, extension functions, data classes, objects, first class functions as well as extensive and expressive lambdas. Kotlin also enhances Java's type inference and type system and takes massive leaps forward with collections.Kotlin vs. ScalaPerhaps, it's better to compare Kotlin against Scala. This comparison might scare some of you quite a bit because Scala has the reputation of being simultaneously intriguing and frightening. It heavily introduces functional programming paradigm to you while still mixing it into familiar object orientation (hence in an awfully lot of cases creating a mishmash of advanced techniques from both paradigms), brings in some new build tools, and gives your internal flow state a frustrating break every now and then due to long compile times.I come bearing both good news and bad news. Let's start with the bad news: Bad news is that Kotlin is similar to Scala, it follows the same path as Scala doesThe good news: luckily, it's only slightly similar to Scala in every aspect.Kotlin & Functional Programming ParadigmThe functional programming paradigm is big part of Kotlin as well. Luckily, it doesn't go into the higher-kinded types, monadic do-continuations, or advanced type theory concepts that make you seek out Bartosz Milewski and his brilliant book on Category Theory. Kotlin introduces easy-to-use collection manipulation functions and functional pipelines for you. You will get your maps, filters, and folds, which in most cases are enough to get to the functional programming path.Java devs that have been lucky enough to jump into Java 8 (hugs and kisses to you Android and/or enterprise developers) will be familiar with the these basics and will feel right at home when they jump into Kotlin. They will also find conciseness and safety of better type system, which will spark their first crush towards the language. It is just so pretty and seamless to pipe these functions together and build a clean pipeline. And when you come back to it after a few weeks, you'll still feel like you can somewhat understand it. Smiles all around.

kotlin basicsKotlin is a new open source programming language like Java, JavaScript, etc . It is a highlevel strongly statically typed language that combines functional and technical part in asame place. Currently, Kotlin targets Java and JavaScript. It runs on JVM.Kotlin is influenced by other programming languages such as Java, Scala, Groovy, Gosu, etc . The syntax of Kotlin may not be exactly similar to JAVA, however, internally Kotlin isreliant on the existing Java Class library to produce wonderful results for the programmers .Kotlin provides interoperability, code safety, and clarity to the developers around theworld. StringBuilder sb = new StringBuilder();in Kotlin becomesval sb = StringBuilder()You can see that functions are defined with the fun keyword, and that semicolons are now optional when newlines are present. The val keyword declares a read-only property or local variable. Similarly, the var keyword declares a mutable property or local variable.Nevertheless, Kotlin is strongly typed. The val and var keywords can be used only when the type can be inferred. Otherwise you need to declare the type. Type inference seems to be improving with each release of Kotlin.Have a look at the function declaration near the top of both panes. The return type in Java precedes the prototype, but in Kotlin it succeeds the prototype, demarcated with a colon as in Pascal

Explore popular language features, Java to Kotlin interoperability, advanced topics, and practical applications by building a variety of sample projects Key Features Understand and leverage the syntax, tools, and patterns by writing code in Kotlin Explore practical topics such as Java interop, concurrency with coroutines, and functional programming Discover how to use Kotlin for build targets like Android, iOS, JavaScript, and backend service Book Description Using Kotlin without taking advantage of its power and interoperability is like owning a sports car and never taking it out of the garage. While documentation and introductory resources can help you learn the basics of Kotlin, the fact that it's a new language means that there are limited learning resources and code bases available in comparison to Java and other established languages. This Kotlin book will show you how to leverage software designs and concepts that have made Java the most dominant enterprise programming language. You'll understand how Kotlin is a modern approach to object-oriented programming (OOP). This book will take you through the vast array of features that Kotlin provides over other languages. These features include seamless interoperability with Java, efficient syntax, built-in functional programming constructs, and support for creating your own DSL. Finally, you will gain an understanding of implementing practical design patterns and best practices to help you master the Kotlin language. By the end of the book, you'll have obtained an advanced understanding of Kotlin in order to be able to build production-grade applications. What you will learn Model data using interfaces, classes, and data classes Grapple with practical interoperability challenges and solutions with Java Build parallel apps using concurrency solutions such as coroutines Explore functional, reactive, and imperative programming to build flexible apps Discover how to build your own domain-specific language Embrace functional programming using the standard library and Arrow Delve into the use of Kotlin for frontend JavaScript development Build server-side services using Kotlin and Ktor Who this book is for If you're a Kotlin developer looking to further their skills or a professional Java developer looking for better or professional resources in order to make a switch to Kotlin, this book is for you.
