Are you looking for a resource where you can find all the answers in relation to Kotlin, then you have come to the right place to find answers to all your question.
In this article, we will cover every aspects of Kotlin so that you can get familiar with Kotlin and take your journey to learn more about Kotlin further.
Let’s dive in!
What is Kotlin?
Kotlin is a statically typed programming language for JVM, Android and the browser.
The syntax of Kotlin is concise with the goal of being less verbose than Java.
The runtime library has been designed to provide interoperability with Java code, meaning that Kotlin code can call upon classes in the Java class library and vice versa. It aims for 100% binary compatibility with existing JVM jar/class files.
This allows Kotlin to run on the existing Android platform without any modification, but also provides support for other platforms like Windows, Linux, macOS, etc.
What is Kotlin used for?
Kotlin is a new and interesting programming language. It can be used to build web applications, Android apps, and even games. Kotlin is open source and great for beginners!
Why Kotlin Over Java?
Kotlin is an alternative to Java for Android development. The advantages of Kotlin over Java, as a programming language for Android development, are:
- Less overhead than Java.
- Tighter integration with the JVM and Android Framework.
- A smaller runtime library than Java.
- Better safety features than Java.
Why use Kotlin?
Kotlin is a JVM based language that has been developed by JetBrains for the purpose of being concise and expressive.
Kotlin requires less code to execute an application, giving it a higher productivity.
Kotlin also takes up less space on your computer, so you won’t have to worry about not being able to install it or running out of room.
Another advantage of Kotlin is that it offers the same level of function as other languages but with more safety because it prevents null pointer exceptions.
How to Install Kotlin?
To install Kotlin you need to find the download page on their website.
Once the download is completed, unzip the folder and then run the “kotlinc” file in order to set up your environment for Kotlin development.
What is a good book on Kotlin?
I’ve recently read Kotlin for Android Development which was a really great book that goes into detail on how to write Kotlin code.
The book is written in a clear, pedagogical fashion with supporting analogies and illustrations. It goes through all of the basic concepts of programming in Kotlin, as well as advanced features like coroutines, extension functions, and much more.
Is Kotlin Free?
Yes Kotlin is free.
What companies are using Kotlin?
Some popular companies that are using it are Square, Basecamp, Pinterest, and Corda.
Does Kotlin have a community?
It has a large community and then hang out on the Kotlin forums and StackOverflow.
Kotlin generates Java-compatible bytecode when targeting the JVM.
Kotlin generates platform-specific code when targeting native (via LLVM).
All main Java IDEs, including IntelliJ IDEA, Android Studio, and Eclipse, support Kotlin. A command line compiler is also provided, which offers simple support for building and executing programs.
Yes. On Android, Kotlin is available as a first-class language. Hundreds of Android applications, including Basecamp, Pinterest, and others, currently use Kotlin.
What is Kotlin when statement?
A when statement is an expression in Kotlin that changes the flow of execution depending on the result of evaluating one or more expressions
The “when” keyword appears before the where clause. It has a similar syntax to if-else statements found in other programming languages.
Kotlin is a compiled programming language that runs on the Java Virtual Machine. Is Kotlin object-oriented or functional? It has both! Kotlin is statically typed, but it also provides the convenience of type inference.
What is a good book on learning Kotlin?
Kotlin for Programmers: The Essentials Course Guide (Kotlin Tutorials for Beginners, Learn Coding Fast) (Patrick Schwerdtfeger)
What is the main difference between Kotlin and Java?
The main difference between Kotlin and Java is that Kotlin is a statically-typed programming language while Java is a dynamically-typed programming language. They also have different syntaxes.
Is Kotlin worth learning?
There are no reasons not to learn Kotlin because developers can still use objects created in java in Kotlin. And the programs written in Kotlin are less bulky because it does not use semicolons to terminate statements. So, Kotlin is almost like a Java but it has some extra features.
What are Kotlin coroutines?
Kotlin coroutines are a straightforward way of managing concurrency without resorting to low-level primitives or asynchrony. It is achieved through a library built on top of the Kotlin language.
What is Kotlin Playground?
The Kotlin Playground is a web-based tool which provides a safe environment for learning how to code Kotlin. Once installed, the tool should be used in any major browser supporting HTML5.
The tool is designed to be used as a first step for those who are interested in Kotlin, but do not know where to start. The Playground does not require installation or download of any application and can be accessed from any place with an Internet connection.
The goal is to introduce the basic syntax of the language by quickly displaying results on-screen. The online version can be used as a tool for learning Kotlin, at any level of expertise.
If you are new to programming, the Playground is an excellent way to see what code is actually executed line by line when you run it. It will also teach you good coding habits, since it immediately tells if your code is syntactically correct.
If you are already an experienced programmer, the Playground is a great way to quickly try out lines of Kotlin code without having to install anything.
The tool can be used in one of two modes: training and online playground. In the training mode the user enters valid Kotlin code into a text area and presses the
Run button to execute it. In the online playground mode, a program is executed as soon as you type it in and press Enter.
In both modes, the results of executing your code appear on a separate area below the text area where you entered your code. This allows you to easily test out different versions of an algorithm and see the difference in results.
What are the Filename extensions of Kotlin?
The filename extensions are .kt, .kts, .ktm
What is the official website of Kotlin?
The official website is https://kotlinlang.org
