Your Complete Guide to the Kotlin Programming Language

2 million programming professionals used Kotlin at least once. Among them, roughly 1 million use Kotlin as one of their 3 primary languages. Keep reading to learn why Kotlin is used in programming and how it might be the right fit for you.

  • Our Learn Kotlin course is perfect if you’re a new developer or new to the Kotlin language.
  • Reduced development time – as Kotlin uses less lines of code than alternatives like Java, developers can read and edit code a lot faster and more efficiently.
  • That’s why to run an application in the browser, we need to use JavaScript.
  • This means developers can spend less time writing boilerplate code and more time solving more critical problems that impact the project’s success.
  • Apart from developing Android apps , Kotlin is also valuable for JVM development.

I do enjoy working with JavaScript, and for a brief moment, I thought that I had found the right tool, but then I was haunted by the fact that JavaScript is dynamically typed. And let’s be honest here, when your back end is serving several hundred thousand users, you really don’t want that to happen. Node.js, however, offered one great feature that I wanted to keep, which is being able to easily write asynchronous code and services. One key difference between Java and Kotlin is that the former is primarily an object oriented programming language while the latter also supports functional programming.

Is Kotlin replacing Java?

In 1949, Assembly Language was first used to simplify machine code, which was necessary for instructing computers. Kotlin is a statically typed, general-purpose programming language developed by JetBrains, that has built world-class IDEs like IntelliJ IDEA, PhpStorm, Appcode, etc. It was first introduced by JetBrains in 2011 and is a new language for the JVM. Kotlin is an object-oriented language, and a “better language” than Java, but still be fully interoperable with Java code. Interoperable with Java – Kotlin runs on Java Virtual Machine so it is totally interoperable with java.

Operator overloading allows the utilization of the same operator on different user-defined data types. Java doesn’t allow operator overloading except for the + function used for addition and concatenation in numeric and string types. If you are looking for software Kotlin developer job developers to help your business with its Kotlin or Java development projects, contact DAC Digital for more information.. If you’re starting a new project from scratch, Kotlin may be the way to go – especially if you’re in the group of Android developers.

With a single codebase and Kotlin’s easy-to-learn syntax and concepts, there’s no need to introduce a second language at all for writing platform-specific code. This also drastically simplifies application maintenance efforts. In short, even though I love Java, I wanted to create a minimum viable product for my project as soon as possible in a short time. And in the case of software development, the simplest way to achieve this is to write less code. Thus, my search for a better language for back-end development continued.

What is Kotlin?

A network management system, or NMS, is an application or set of applications that lets network engineers manage a network’s … Kotlin has tooling support from Android with tools optimized for Android development, including Android Studio, Android KTX and Android SDK. Sagara is one of the leading software house based in Jakarta.

Kotlin developer meaning

It solves a lot of pain points of Java, so the new apps are mostly written in it, and the old ones are being rewritten in it. 💡 The average annual income of professional developers worldwide (US and non-US) is between $33,000 and $95,000 for various programming languages. 💡 The average annual income of professional developers in the US is between $70,000 and $177,500 for various programming languages. With Kotlin, you can enjoy many features that aren’t available in Java. For example, Kotlin has null safety built into the language, meaning you can avoid those pesky NullPointerException errors. It also supports data classes and lambdas, which can make your code more concise and expressive.

Investing in Unit Testing: Benefits and Approaches

When you let the framework take care of certain mundane aspects of coding, you can focus on more important things. Kotlin is all about high readability, simplicity, and the facilitation of the app development process. Apps that need to maintain platform independence and be cross-compiled for multiple platforms as well as Android. Kotlin can perform these functions while Java cannot due to its use of bytecode which can only compile code for one specific platform at once.

There is no doubt that in the years to come more and more companies will choose Kotlin for their projects. Kotlin programming language runs on the Java Virtual Machine , which makes it a direct competitor to more widely known and mature Java with over 20 years of history. Both languages can be used in the same spheres, including server, client, web, and Android developments. Kotlin is an open-source programming language, which history started in 2016. The language is developed by JetBrains that are working on making Kotlin the main programming language for both Android and iOS. Data Scientists can use all the standard Java libraries that they used for Java projects but write their own code in Kotlin.

Developers no longer need to use Java, an established language, but with a lot of issues. Even though some of the problems were solved in Java 8 and further addressed in Java 9 and Java 10, its popularity has wavered. Our Learn Kotlin course is perfect if you’re a new developer or new to the Kotlin language. It’ll introduce you to fundamental programming concepts and teach you how to write Kotlin code. In Kotlin language, there are many extensions that allow adding the functionality without inheriting from the class using no decorative pattern. There are some that will say Kotlin isn’t yet an essential programming language and therefore it’s not important to learn it now.

One of the most useful coroutine scopes is runBlocking, which applies to the scope of its code block. For Groovy fans, Kotlin implements builders; in fact, Kotlin builders can be type checked. Kotlin supports delegated properties, which can be used to implement lazy properties, observable properties, vetoable properties, and mapped properties. If you want to make use of optimizations available in newer versions of Java, you can explicitly specify the target Java version from 9 to 18.

This is another point where two programming language differs. In Java, such expressions are checked during the compilation process. If a method has such an expression, the method should either handle it or developers need to specify them with the keyword ‘throws’. Kotlin, on the other hand, offers inherent null safety, meaning that no variable or object can be assigned with a null value. As a result, developers need to write less code as there is no need to come up with solutions to sidestep the issue. When we talk about Android development, in-built null safety makes Kotlin an obvious leader.

Kotlin is the best choice for Android development

Kotlin is a powerful, modern, and efficient language with many useful features. Kotlin uses aggressive inference to determine the types of values and expressions if they’re not clearly stated. It makes the language even more distinctive from Java, which sometimes requires repetitious type specifications. Kotlin supports Java-like Char and String types to represent text. You denote single characters with single quotes,’c’, and Strings with double quotes “this string”`.

Kotlin developer meaning

Built from the ground up for both functional programming and object-oriented programming. Kotlin is a rising programming language that aims to address the flaws of Java and be more seamlessly tied with the adaptable needs of the modern world. While once a niche language, Kotlin is quickly growing and has many companies switching from Java to Kotlin.


It facilitates desktop, web, and backend server application builds using established Java frameworks like Spring, Vaadin, Spark, Hadoop, etc. Kotlin also allows for higher-order functions, meaning functions can be passed or returned like other values. One of Kotlin and Java’s biggest differences is that functions can exist outside of classes in Kotlin. On the other hand, Java is rigidly bound to object-oriented programming and requires everything to be within class definitions. All the following types are objects at runtime but do transpile to the respective Java primitive types in Java bytecode.

The while loop executes the body of code repeatedly so long as the listed conditions remain met. The standard while loop checks for the condition before the code is executed, and the do-while loop checks after the code is executed. Kotlin’s type inference system is very robust and allows implicit typing of literals, objects, and complex structures, like lambda expressions. Unlike Java, Kotlin allows you to easily make multi-line strings using three sets of double quotes, “”””””. Java only offers concat and line.separator for multi-line strings, which are less concise and require special implementations.

It is very similar to Java in that Kotlin/JVM compiles down to Java bytecode, so for those back-end engineers who have a JVM background, Kotlin will be easy to grasp. This use case is worth describing separately, as Android app development is one of the most popular uses for Kotlin. While Java has been the go-to language for Android development for a long time, Kotlin is a more modern option that is becoming increasingly popular. For some, Kotlin became a new Android language, used in mobile development to write Android apps, compile code, as well as for replacing other programming languages. Just what you would expect from one of the most popular programming languages out there.
