Kotlin Tutorial: Easy Steps to Get Started with the Modern Language
As the world evolves into the digital age, so does the language of programming. Kotlin is a modern language that has rapidly gained momentum since its release in 2011. It is a statically typed, open-source programming language that aims to make programming more concise and safer by eliminating common errors that occur in Java. In this tutorial, we will show you how to get started with Kotlin in easy steps.

Step 1: Set up the Environment

To start working with Kotlin, we need to set up its environment. To do this, first, we need to download and install a Java Development Kit (JDK). Kotlin compiles into Java bytecode, which means it runs on the JVM (Java Virtual Machine). Therefore, we need to have a JDK installed to run the Kotlin platform. You can download and install a JDK from the Oracle website.

Once the JDK is installed, we need to download and install the Kotlin compiler. You can download the Kotlin compiler from the official Kotlin website. After downloading the compiler, install it on your PC and set the environment variables.

Step 2: Create a Kotlin Project

After setting up the environment, we can create a Kotlin project in any Integrated Development Environment (IDE) of our choice. IntelliJ IDEA is the recommended IDE for Kotlin development. You can download IntelliJ IDEA from the JetBrains website.

To create a Kotlin project in IntelliJ IDEA, follow these steps:

1. Click on “Create New Project” from the welcome screen or select “New Project” from the File menu.
2. Select “Kotlin” from the available options.
3. Choose the project SDK (Java SDK) that you installed in step 1 and click “Next.”
4. Provide a name and directory to save the project.
5. Click “Finish.”

Step 3: Write Kotlin Code

Now that we have created a Kotlin project, we can start writing Kotlin code. Kotlin syntax is very similar to Java, but it eliminates some of the boilerplate code required in Java. Kotlin is a concise language, which means we can accomplish more with fewer lines of code.

To begin writing Kotlin code, create a new Kotlin file and start writing the code in it. Here is an example of a Kotlin program that prints “Hello, World!” to the console:

fun main() {
println(“Hello, World!”)

This program is similar to a Java program, but with Kotlin’s syntax, it eliminates the requirement of a “main” method and the semicolon (;) at the end of the line.

Step 4: Run the Kotlin Program

After writing the Kotlin code, we can run the program by clicking the Run button in the IDE. It will compile the Kotlin code into Java bytecode and run it on the JVM.


Kotlin is an excellent language for modern application development that saves time, reduces errors, and is easy to learn. With the help of this tutorial, you can get started with Kotlin in easy steps. So, start exploring the features of Kotlin today and begin creating exciting new applications.
