How to set up Kotlin in Linux
Kotlin is a modern programming language that works with the Java Virtual Machine (JVM). It is a popular alternative for Android app development and other JVM-based apps considering its simple syntax, feature-rich functionality, and smooth integration with existing Java code.
Advantages of Kotlin
There are many benefits of using Kotlin for mobile app development. Some of them are given below:
Kotlin has a clear and simple syntax that reduces boilerplate code, improving code maintenance and making it more readable.
It has smart casts which automatically cast variables after type checks, eliminating the need for explicit type casting and improving code clarity.
It has built-in coroutines that simplify asynchronous programming, making it easier to write concurrent and non-blocking code.
It can target multiple platforms, including JVM, Android, JavaScript, and native platforms, which makes it a versatile language for many applications.
Installing Kotlin
To set up Kotlin on our system, we will show the step-by-step approach of installing Kotlin.
First, we launch the terminal on our Ubuntu system and update the package list using this command:
sudo apt update
Next, to install the Kotlin compiler, we execute the following command:
sudo apt install kotlin
Verifying the Installation
Once the installation is complete, we can confirm if Kotlin is successfully installed by checking its version.
For verification, we run this command in the terminal:
kotlinc -version
Upon execution, we will see the version information displayed on the screen.
Running a Kotlin program
We have ensured the successful installation of Kotlin on our system. Now, let's look at a code example that will familiarize us with its simple syntax and methods.
fun main(){println("Educative Answers is a free web encyclopedia.")}
Here, we print a string as output that tells us Kotlin is operating smoothly on our compiler.
Conclusion
In conclusion, Kotlin is a versatile language with clear syntax and modern capabilities. It is an excellent option for diverse applications, Android app development, and backend services. By reducing redundant code and boosting developer efficiency, Kotlin is an essential tool for creating effective software solutions.
