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

* 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.

Kotlin Read the First A Practical, Easy-Mind Guide for Beginners and Working Developers Kotlin is a modern language, but many Kotlin books still feel heavy, academic, or unnecessarily long. Kotlin Read the First was written to be different. This book is designed for developers who want to understand Kotlin quickly, build the right mental model from the start, and apply it immediately in real projects—without getting lost in theory or noise. Whether you are completely new to Kotlin or coming from Java or another language, this book focuses on what actually matters first. What this book gives you A clear, structured introduction to Kotlin fundamentals Simple explanations that reduce confusion and cognitive load Practical code examples you can run, modify, and reuse Clean mental models that help you reason about Kotlin features A learning pace that respects your time Instead of explaining everything, the book explains the right things in the right order. Topics covered This book walks you through Kotlin from the ground up, including: Kotlin basics and syntax Variables, types, and null-safety Control flow and functions Collections and standard library essentials Object-oriented Kotlin (classes, inheritance, interfaces) Data classes, enums, and sealed classes Practical Kotlin patterns you will see in real codebases Each chapter is intentionally concise and focused, so you can make steady progress without fatigue. Who this book is for Developers learning Kotlin for the first time Java developers transitioning to Kotlin Android or backend engineers who need Kotlin quickly Busy professionals who want a fast but solid foundation Readers who prefer clarity over excessive detail You do not need prior Kotlin experience to read this book. The Easy Mind approach This book is part of the Easy Mind Series, a collection of technical books built on one principle: Programming languages are tools, not identities. You don’t need to memorize everything. You need to understand the core idea, recognize when to use it, and move forward with confidence. The Easy Mind approach emphasizes: Practical understanding over theory Clean thinking over clever tricks Delivery and maintainability over over-engineering Why read this book first If you are overwhelmed by large reference books, long tutorials, or fragmented online resources, Kotlin Read the First gives you a clean starting point. Read it first. Understand clearly. Build with confidence.
