Kotlin programming language Wikipedia

Here at Source, we like to see ourselves as a future-facing company. It means we’re always looking to innovate and adapt and keep up with the latest advances in the markets that we recruit for. That’s why we write these articles – we want to make sure we’re always ahead of the curve. It is also designed to work well for web development and server-side development.

Kotlin has classes with constructors, along with nested, inner, and anonymous inner classes, and it has interfaces like Java 8. To create a class instance, call the constructor just like a regular function. On 7 May 2019, Google announced that the Kotlin programming language is now its preferred language for Android app developers. Since the release of Android Studio 3.0 in October 2017, Kotlin has been included as an alternative to the standard Java compiler.

What is the Fastest Programming Language?

By eliminating boilerplate, Kotlin significantly reduces the size of code compared to Java. It all results in a less costly development process and easier project support. You might be wondering why you should take time compiling Kotlin code, even though JavaScript is so widely used.

If you look at GitHub and search for Android repositories, you’ll find about 50,000 that use Java, 24,000 that use Kotlin, and 73 that use Scala. Yes, it’s possible to write Android applications in Scala, but few developers bother. It is not completely obvious from this example, but Kotlin has relaxed Java’s requirement that functions be class members. In Kotlin, functions may be declared at top level in a file, locally inside other functions, as a member function inside a class or object, and as an extension function. Extension functions provide the C#-like ability to extend a class with new functionality without having to inherit from the class or use any type of design pattern such as Decorator.

What advantages does Kotlin give me over the Java programming language?

Kotlin especially comes in handy for big projects and teams. 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. By including the “data” keyword in the class definition, you can avoid setting up everything manually. The compiler takes on the task and generates all necessary getters and setters automatically.

While Java and Kotlin both have ample documentation, Kotlin has a smoother learning curve. If you don’t want to write code in two different programming languages, you can compile Kotlin code to Kotlin developer job JavaScript. This way, it is possible to use the code for both client and server web developments. Out of all available and popular programming language options, Kotlin is one of the youngest.

On the other hand, Java is simple and has fewer extra features than Kotlin, thereby compiling faster. Because the difference is only slight, the battle of Kotlin vs. Java based on performance is also a draw. Finding a solution to a task in Kotlin requires more time than with Java, meaning that the language has a higher cognitive load.

It can be used for mobile, web, server-side, desktop, and even embedded systems development. Thanks to its mechanisms for sharing code, you can easily create multiplatform libraries and applications that work on multiple platforms.” – JetBrains, Kotlin developers. Main class in KotlinThe Kotlin programming language combines https://wizardsdev.com/ object-oriented programming and functional programming in an unrestricted manner. With this feature, Kotlin is powerful and a good option for both Android and server-side applications. The best part about KMM is that you won’t need to introduce new programming languages to a codebase to make a cross-platform app.

It’s been over a decade since the first apps were introduced to the world in Apple’s App… We have all the tools and downloadable guides you need to do your job faster and better – and it’s all free. It makes sense to use Kotlin for server-side web development. Still, you can also use Kotlin for front-end development using Kotlin/JS. 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.

A productive way to write server‑side applications

It was originally created by James Gosling at Sun Microsystems in the early 1990s. Autocode, developed in 1952 by Alick Glennie, was the first compiled programming language, meaning it could be directly translated into machine code. In 1957, FORTRAN was invented by John Backus for high-level scientific, mathematical, and statistical computations. In this article, we will explore the origins, history, features, and use cases of both languages to help you make an informed decision about which to use. We’ll start with the background of programming languages in general and finish with an easily digestible comparison table between Java and Kotlin.

The Spring Framework officially added Kotlin support with version 5 on 4 January 2017. To further support Kotlin, Spring has translated all its documentation to Kotlin and added built-in support for many Kotlin-specific features such as coroutines. In addition to Spring, JetBrains has produced a Kotlin-first framework called Ktor for building web applications. Kotlin is inspired by existing languages such as Java, C#, JavaScript, Scala and Groovy.

And in some cases, we can use JVM Platform Annotations in Kotlin to access Kotlin’s codebase from Java code. Functions in Kotlin require you to define the function’s name, inputs, and outputs. All function definitions begin with the fun keyword and contain a block of code executed when the function is called.

Kotlin has the ability to cross-compile and run on multiple platforms, while Java is limited by its use of bytecode which can only be compiled for a single platform at once. There are many cases in mobile development where developers need to create an Android version as well as iOS versions or even Windows versions. Well, whenever anyone talks about Android app development, then in most experts’ minds, just two technologies’ names strike, i.e., Kotlin and Java.

Extension functions are useful when trying to use the functionality of third-party libraries you can’t modify but can extend. Unlike inheritance, you can extend a class without full access to it. Clearly, Kotlin is more concise, only using two lines of code. This is because Kotlin allows functions to exist outside of classes, meaning we don’t have to declare a HelloWorld class. Type inference is a feature that allows the deduction of data types for specific expressions automatically. Java does not allow type inferences as developers need to specify each variable before a declaration.

• This is considered to be the first officially stable release and JetBrains has committed to long-term backwards compatibility starting with this version.
• The advantage of this class is that it provides self-generated code and avoids the implementation of methods within the class.
• One of the most useful coroutine scopes is runBlocking, which applies to the scope of its code block.
• All this makes Kotlin very well suited for large and complex app development projects.
• Keep reading to learn why Kotlin is used in programming and how it might be the right fit for you.

If you’re looking for a language with solid support from Google, then Kotlin may be the best choice, as Android Studio 3 now supports Kotlin development. However, if you need speed or want an open-source project with more flexibility (especially in terms of third-party libraries), Java might be the right option for you. If you want to contribute to the code, go to GitHub and check out the latest version and follow the instructions on how to build Kotlin from source. After that, you can start picking some pending tasks on the issue tracker.

They can be used to achieve a high level of performance on the back end. When it comes to writing REST APIs, there are some extra steps one must take, like starting an embedded server or parsing the request, and of course, no one wants to do it manually. Java has Spring Boot, which makes things really easy, and luckily, Kotlin has a framework called Ktor. Ktor is a web framework for building asynchronous servers.

Android accounts for over 70% of the market share of mobile phones, so even if Kotlin was only for Android development, Kotlin developers would be in high demand. Kotlin can run anywhere Java runs, so you can use it to build cross-platform apps. The world’s leading streaming service Netflix used the Kotlin language to rebuild their UI player for the android app of Netflix. It can be used for both server-side and client-side applications, both for web and Android. Developers will soon be able to use it for macOS and iOS platforms too.
