Is Kotlin Easy to Learn for Beginners?

Kotlin is a popular language and an easy language to learn. If you’re just getting your feet wet in coding, Kotlin is an excellent starting place.

If you came here for a one-word answer, it is yes; Kotlin is very easy for beginner coders to learn.  It’s also easy to teach, and 22 of the top-ranking colleges teach Kotlin in their curriculum.

If you’ve dabbled in coding or are interested in getting started, you may have heard of Kotlin. Kotlin is an open-source programming language that was developed by JetBrain in 2011. It works on multiple platforms, interoperates with Java, and is Google’s preferred language for Android app development.

Why Use Kotlin?

Kotlin is very popular, and many large companies, including Uber, Pinterest, Reddit, Twitter, and Slack use it. If you’re familiar with Javascript, you will pick it up quickly. This coding language is popular for many reasons.

  • It’s easy to pick up, even for beginner programmers.
  • The language is concise and doesn’t require a lot of supporting code.
  • Kotlin operates on many platforms, including native code, Android devices, JVM (Java Virtual Machine), and in-browser script through javascript.
  • It’s compatible with the Java infrastructure and libraries.
  • The code compiles quickly.
  • You can use many different IDEs (Integrated Development Environment) such as Eclipse, Android Studio, and IntelliJ IDEA or the command line.

Learning to Use Kotlin

Get familiar with Kotlin and see how easy it is to learn. Once you’re familiar with the language, set yourself up to code in Kotlin. 

Getting Started

  1. Download and install the Java IDEs of your choice, such as IntelliJ IDEA. 
  2. Create a new project. Go to File – New Project and select Kotlin. 
  3. Go through the new project wizard, create a name for your project, and click finish to start your program. You can use the default configurations.
  4. Under your project name, expand the folder src. There will be a sub-folder main. Click on main.kt.
  5. A sample source code will display, which you can edit to create your own code. 

The structure of a simple code can look as follows:

Fun main () { Println (“This is the text that will display on your screen when you run the program.”)}

  1. Play around with the code to get familiar with the language and its usage. 

Kotlin Programming Basics 

Kotlin is similar to Java, so if you’re familiar with it – or any programming language – the style will be familiar. If you’re a beginner programmer or Kotlin is the first language you are learning, it’s easy to learn, and you will get the hang of it quickly. The following are standard basics in Kotlin to get you started.

  • Print – will display the text that you type in. 

Print (“Hello!”)

Print (“Goodbye!”)

When you run the program, it will display on your screen:

 Hello!Goodbye!

  • Println – will display on your screen the text you entered with a line break after.

Println (“Hello!”)

Println (“Goodbye!”) 

When you run the program, it will display on your screen:

Hello!

Goodbye!

  • Int – refers to an integer and represents a number.
  • val – refers to a value that you will need to use within the code. Values that you will use in the program must be introduced at the beginning and assigned the data that it will be storing by introducing it with the prefix val.

For example, if your code will need to use the number 5, you can declare it as:

Val x: Int = 5

This tells Kotlin that x will be an integer, and you are assigning it the value of 5.

  • Var – a variable is a placeholder for a value that you can change and use again throughout the program. 

For example, if the code will be using a number that changes, make it a variable. 

Var z = 5

In this case, variable z is assigned the value of 5.

Z +=1

Variable z is now will now be increased by one and z = 6. Each time this code is run, the value of z will increment by one.

In Conclusion 

Kotlin is a popular language and an easy language to learn. If you’re just getting your feet wet in coding, Kotlin is an excellent starting place.
