Are you looking to learn Kotlin and become an Android/Java developer quickly in a cost-effective way? Here’s the ultimate list of online courses, YouTube videos, and Amazon books that will help you to become a master of Kotlin programming.

Kotlin is a modern programming language. It makes Android and Java coding much easier than existing programming languages. Also, Google has endorsed Kotlin as the official app development language for the Android operating system.

Therefore, many developers are now in the race to learn Kotlin. Read on to find some truly helpful, affordable, and high-quality resources to educate yourself on Kotlin.    

Kotlin and Its Benefits

Kotlin and Its Benefits

Kotlin is a modern, free, open-source, general-purpose, and intuitive programming language. Jet Brains developed this coding language for Android and Java Virtual Machine (JVM) in the first place. Later on, the Kotlin Foundation was set up, and the language got multiplatform features like: 

  • For Native Code, Kotlin/Native
  • For JS Code, Kotlin/JS
  • For JVM Code, Kotlin/JVM

Developers can now use Kotlin for multiplatform mobile apps, web frontend for mobile apps, Android development, and server-side solutions. 

Key benefits of Kotlin are: 

#1. Safe, concise, and modern coding language that developers can pick up in a few hours and develop outstanding apps immediately.

#2. It is one of the most productive programming languages for server-side coding programs.

#3. Developers can use one application logic for many platforms like Android, web, iOS, and computers when coding in Kotlin.

#4. Shareable application code across many platforms does not interfere with applications’ native code and UI.

#5. Java and Kotlin work side by side. Hence, developers can utilize their Java programming knowledge while using Kotlin.       

Kotlin Vs. Java as an Android Development Tool

Kotlin Vs Java as an Android Development Tool

Kotlin and Java programming languages are both accepted for Android app development by Google. Though Google suggests, developers use Kotlin for the maximum part of the programming language. However, Java is 100% supported when needed.

Readability is a crucial concern when developing a mobile app. Kotlin is highly readable when compared with its Java counterpart. Check out detailed information on Kotlin vs. Java.
