This hands-on training ensures that you grasp essential concepts, offering a Kotlin free course with certificate upon completion. Ideal for those just starting, this course combines theory and practice to help you become proficient in Kotlin, one of the most popular languages for Android development.

Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin’s standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin is a programming language which is widely used by Android developers everywhere.

Learn Kotlin Basics

Our course covers everything you need to learn Kotlin basics, designed specifically for newcomers. This Kotlin basics for beginners module breaks down complex concepts into easy-to-understand lessons, giving you a solid foundation to build upon. Whether you’re interested in mobile development or looking to expand your programming toolkit, this course is tailored to suit your needs.

Kolin is focused on interoperability, safety, clarity, and tooling support. Versions of Kotlin targeting JavaScript ES5.1 and native code (using LLVM) for a number of processors are in production as well. Kotlin originated at JetBrains, the company behind IntelliJ IDEA, in 2010, and has been open source since 2012.
 

About Kotlin Programming

•  Open Source – The Kotlin compiler, Intellij IDEA plugin, and build tools are all open source.
•  Interoperable – Kotlin is 100 percent interoperable with Java. This means all your current Java/Android code works seamlessly with Kotlin.
•  Concise – Compared to Java, Kotlin code are much more concise. Also, Kotlin code is much more expressive (easier to understand and write).
• Easy– It is particularly easy if you already know Java.
•  Tool-friendly – Kotlin is developed by JetBrains, the company renowned for creating development tools. You can choose any Java IDE to write Koltin code.
