How to learn Kotlin: A guide for beginners & Android developers

A data class is a class that does not perform any operation and only contains a state. The advantage of this class is that it provides self-generated code and avoids the implementation of methods within the class. By including the “data” keyword in the class https://wizardsdev.com/ definition, you can avoid setting up everything manually. The compiler takes on the task and generates all necessary getters and setters automatically. You can perform the same tasks and implement the same features with the help of Kotlin and Java.

• Kotlin can also be used for developing desktop apps since both JavaFX and Swing UI libraries can be called from Kotlin.

Modern, concise and safe programming language

Java has support for functional programming but it’s only available in Java 8, whereas most Android development is done with Java 6 and 7. To help manage the quality of your code, Kotlin makes use of type inferencing, eliminating much of the frustrating and overly tedious syntax that Java developers face. Often, code written in Kotlin is more concise, but it also happens to be a little more complex for those used to programming in Java. Currently, it’s most prominent for Android application development. However, its usage for developing server-side applications for the JVM is increasing.

Thus, you can also consider a popular Kotlin tutorial to get started on your journey of becoming an expert Kotlin developer. It is yet another outstanding feature of Kotlin that makes it a great choice for Java developers. Kotlin is completely interoperable with Java, which means you can use it literally in almost all Java-based applications. Moreover, it is also relatively easy to integrate Java applications to Kotlin, and you can use both the programming languages simultaneously in a single application. Also, Kotlin is well-known for making it possible to develop cross-platform apps quickly. Several advantages like these make Kotlin one of the best modern programming languages to learn today.

There is no need to have two separate iOS and Android development teams, which makes Kotlin a more time and cost-efficient programming language. With over 600 programming languages out there, the process of choosing the right one to learn or develop a project has become a real challenge. Learning Kotlin can teach you a lot about language design and some of the shortcomings of Java that you may not have been aware of previously. Therefore, it can be a great way to learn about modern programming language features that you will encounter in other languages as well, such as TypeScript, Scala, Go or Rust.

It can transpile to Java bytecode to run on the Java Virtual Machine or Android. Interestingly, it can also transpile to JavaScript code or native bytecode, allowing you to use it for many different use cases. As a language with the potential to be a full-stack technology, Kotlin may be also transpiled to JavaScript to be used on the front-end. The kotlin/JS package allows you to build code that targets client-side JavaScript, and interacts with DOM elements and graphics. Another way to apply Kotlin for the creation of captivating web applications is by using it in conjunction with React. While salaries are good to understand for hiring developers for full-time and long-term, you might just need a developer for a period of 3-6 months or 6-12 months.

Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility Kotlin developer job and benefits of native programming. The Kotlin library for accessing browser-specific functionality, including typical top-level objects such as document and window.

JVM provides a great environment for game development, and Kotlin developers are using it to their advantage. Google’s steadfast support for Kotlin inspired a sharp rise in the language’s popularity over the last two-three years. In StackOverflow’s 2020 Developer Survey, Kotlin ranks as the fourth most admired programming language.

Kotlin Apprentice

Boilerplate code is a common description of verbose languages where sections of code have to be included in multiple places with little to no alteration. Interviews are challenging as your technical knowledge and skills are put under test to assess if you are the right fit for the job role. Also, it’s true that your personality and soft skills also matter significantly for cracking an interview, but let’s keep them aside and focus on the technical aspects. First, a user needs to be directed to a signup page, which requires basic user information like name and phone number. Also, users would need to provide their email addresses and choose a password that will let them log in securely. Also, whenever a new Kotlin release is out with some new features, the first place you’ll be able to learn about the same is the official docs.

In one part, due to Google officially supporting it for Android development, and, secondly, because Android is still stuck on Java 6. Kotlin, with its modern features, spread rapidly among the Android developers’ community. Today, Java is really popular for backend development and Kotlin can be used for any kind of server development. Whether it is web apps that serve HTML content, a backend for REST APIs or Microservices, Kotlin can do the job. Not only that, thanks to the Kotlin JavaScript compiler, it can also be used for building frontend web Apps. So it is entirely possible to create a web App using only one language.

However, the virtual machine doesn’t support all environments, including embedded systems and browsers. That’s why to run an application in the browser, we need to use JavaScript. Developers no longer need to use Java, an established language, but with a lot of issues.
