Kotlin Tutorial Kotling Programming Language

One of the hottest new programming languages, Kotlin is being prioritised by some of the world’s leading companies. Since first hitting the scene in 2016, this open-source language has quickly built a reputation as one of the key pillars to the future of development. In 2016, Kotlin 1.0 version was released, which was developed by Jet Brains in Russia. So the team decided to create a language that is compatible with Java and with all the features they wanted.

Thus, Kotlin is a fine choice if you plan to develop an app for your business. The major advantage of Kotlin is you can use it for any kind of development – be it server-side, client-side web, and Android. You also can use it for mobile and server-side applications, client-side with JavaScript or JavaFX, and data science, etc. On the operation systems front, you can use Kotlin in iOS, macOS and embedded systems, etc.

What Is Kotlin? A Brief Introduction

For example, val is used to write non-changeable declarations, whereas var is used to write changeable declarations. However, there are some minor distinctions between the two languages. When declaring a lambda function, for example, the arrow should be placed differently depending on whether a single or double arrow is used. The data class in Kotlin is equivalent to the case class in Scala.

The history of Kotlin dates back to 2011 when Jetbrains, a company headquartered in Prague, Czech Republic, developed a unique language for JVM. Kotlin, which got its name from Kotlin Island, near St. Petersburg, became open source in 2012. The first official version of Kotlin came in 2016 and got support for Android in 2017 by Google.

What is Kotlin? Guide to Kotlin Programming Language

It combines object-oriented and functional programming features. Over 80% of the 1000 most popular Android apps currently use Kotlin. Kotlin is a general-purpose, statically typed programming language developed by Jet Brains.

Kotlin is a concise language that helps developers reduce lengthy lines of code. As a null safe language, Kotlin handles NullPointerException and null references using its safe call operator ? Kotlin can be compiled quickly and supports both primary and secondary constructors.

Why Should We Use Kotlin?

Conversational AI is a type of artificial intelligence that enables computers to understand, process and generate human language. At least one of the datapoints contained must be a parameter. Pinterest was the poster child for Android apps written in Kotlin as early as November 2016, and it was mentioned prominently at Google I/O 2017 as part of the Kotlin announcement. In addition, the Kotlin team likes to cite the Evernote, Trello, Gradle, Corda, Spring, and Coursera apps for Android. Speaking of avoiding common errors, Kotlin was designed to eliminate the danger of null pointer references and streamline the handling of null values.

From Pinterest and Coursera to Trello and Evernote – there are plenty of great examples and success stories. Even though the syntax of the language is not compatible with Java, Kotlin is designed to interoperate fully with it. This means that your existing codebase written in Java can interact properly with Kotlin, and vice versa.

Kotlin Tutorial

Kotlin makes it possible to write short versions of Java programs that would be too long to write in Java. This means that it does the same thing with less code but gets the same results. The less time it takes to write a shortcode, the more money it saves.

It allows for building scalable, fast applications able to handle thousands of users. Kotlin is an open-source, general-purpose programming language originally created for the Java Virtual Machine . The language was created by JetBrains, that started working on Kotlin in 2010, and the project was made open-source shortly after in 2012. The https://globalcloudteam.com/ 1.0 version was released in 2016, and no more than three years later, Google announced that Kotlin is the preferred language for Android. Kotlin is influenced by other popular programming languages such as Java, C#, JavaScript, Scala and Groovy. Kotlin provides interoperability, code safety, and clarity to the developers around the world.

Multiplatform Development

Learning Kotlin is a great idea if you want to advance your career as an app developer. Having read this guide, you should now have a basic understanding of what it is and how it works. Kotlin removes one of the standard Java defaults on NullPointer Exception. Moreover, Kotlin supports designated properties—and it has relaxed Java’s requirement. Kotlin is a more concise and streamlined edition of Java, but is interoperable with it; you can call any Java code from Kotlin and vice-versa. Above all functions, Kotlin has two particular kinds of functions named Lambda function and Inline function.

• Easy Language − Kotlin supports object-oriented and functional constructs and very easy to learn.
• In that announcement, Google declared Kotlin as its preferred language for android app development and endorsed complete support for it.
• Kotlin is compatible with Java, it is fully interoperable with Java, and you can convert the Java file to the Kotlin file with just a script.
• Destructuring declarations decompose an object into multiple variables at once, e.g. a 2D coordinate object might be destructured into two integers, x and y.
• Kotlin 1.3 added support for contracts, which are stable for the standard library declarations, but still experimental for user-defined declarations.
• The app has features but is also easy to use and configure for novice users.
• Ruby on Rails is the programming language and framework combo platter that effortlessly brings ideas to life.

In fact, it was inspired by languages such as Java, C#, JavaScript, Scala and Groovy. Kotlin is an open source programming language with cross-platform and statically typed inference. Kotlin first appeared in 2011, but it didn’t get much attention in the first five years.

What exactly is Kotlin?

By sharing this common code on the back-end development among different modules, levels of efficiency can skyrocket. Many programmers use Kotlin/JVM for back-end web development because they’re writing less code than they would with Java, even if it’s the same code. If you are looking to build a software development career, you can check the Post-Graduate Program in Full Stack Development by Simplilearn. It can be the ideal solution to help you build your career in the right direction. In this tutorial on what is Kotlin, you looked at the importance of the Kotlin language. You also explored what Kotlin is, and the history of the Kotlin language.
