What is Kotlin programming language?

Kotlin is a free, open-source, general-purpose programming language. Released by JetBrains in 2016, Kotlin is fully interoperable with Java and supports both object-oriented and functional programming. Kotlin was originally intended for use with Java Virtual Machine (JVM) and Android, but can now be used for Windows, Linux, iOS, macOS, watchOS, and other operating systems. 

Kotlin has several features that make it versatile, such as anonymous functions, closures, and higher-order functions. Since Kotlin is compatible with Java programming, developers can use Kotlin and Java in a single project. 

Kotlin programming language allows you to accomplish your goals with fewer lines of code than other, similar, programming languages. It can help reduce security vulnerabilities and its clean code makes it easy to maintain.Footnote 1

Interested to learn how to use this programming language? An introductory course or Kotlin tutorial can cover foundational steps for building Android apps. These courses can teach learners how to:

  • Add images and text to applications.

  • Use classes, objects, and conditionals to create interactivity.

  • Build layouts by using the design guidelines and UI development best practices. 

  • Enhance navigation for the user.

  • Write coroutines for complex code.

Explore Kotlin programming jobs

Learn Kotlin to support a number of different roles, including:

  • Kotlin developer: use Kotlin to plan, design, and develop apps and software. Developers also review apps and systems, focusing on ways to improve those systems through optimization.Footnote 2

  • Computer programmer: write, modify, and test code and scripts using programming languages like Kotlin. A programmer is responsible for taking the design that a software developer has created and then writing code so that the computer can execute that design. A programmer also tests the applications and software that they have created to ensure they work properly.Footnote 3

  • Software developer and tester: help design and create new programs and systems. Software developers will analyze a user’s needs, then design and help to develop software to solve those challenges. They may create several models and diagrams to show programmers the code that an application requires, and then they will maintain and test a program to confirm that it functions appropriately.Footnote 4

Pursuing a bachelor’s degree and a master’s degree in a related field, like computer and information technology, engineering, or math, can give you the educational foundation to prepare you for these careers. Keep in mind that specific educational requirements will vary depending on the job. Some jobs might require a bachelor’s degree, while others might prefer that candidates have a master’s degree.Footnote 5

In addition to bachelor’s and master’s degrees, boot camps offer you a chance to pursue specialized training and education in coding, cybersecurity, and other topics that can be helpful for your career. 

How to become a Kotlin programmer online 

As a Kotlin developer or programmer, you could use Kotlin when designing and developing apps and software which require expert-level knowledge of the programming language, as well as Java programming. It may be important to build a strong knowledge of databases and a familiarity with web frameworks. Experience with SQL, web development solutions, and object-oriented fundamentals can also be essential, as are strong programming skills and hands-on experience with software development and app design.Footnote 6

A bachelor’s degree in data science can help you to learn and apply some of these foundational skills. However, more specialized coursework, like a coding boot camp, may  also be a helpful learning path, particularly if you want to focus on a specific skill.
