The ABCs of Kotlin Programming

Introduction

Welcome to our new blog post. In today’s write-up, we will explore ‘The ABCs of Kotlin Programming.’ For those who are not aware, Kotlin is a statically-typed programming language that runs on the Java virtual machine, making it an excellent choice for Android app development. Without further ado, let’s dive right in.

A. What is Kotlin?

Kotlin is an immensely pragmatic language that is designed to improve existing Java models by offering solutions to their shortcomings, while being fully interoperational. It’s developed by JetBrains, a company known for creating famous developer tools.

B. Major Advantages of Kotlin

  • Interoperable with Java
  • Lean syntax, meaning less boilerplate code
  • Null safety native, preventing a large class of errors
  • Great tooling (it’s developed by a tooling company)

C. Basic Syntax

At first glance, Kotlin syntax may seem unfamiliar. However, it’s actually quite straightforward once you grasp the basics. Here are essential aspects:

  • Variables: Kotlin has two types of variables: mutable (var) and immutable (val).
  • Functions: Functions in Kotlin are declared using fun keyword.
  • Nullability: Kotlin has built-in null safety. Any variable can be declared as nullable by adding a ‘?’ after the variable type.

Conclusion

It would be fair to conclude by stating that Kotlin offers several benefits over its close rival, Java. Its straightforward syntax, operability with Java, and null safety features make Kotlin a potent programming language. With more and more developers valued on these aspects, now might be the best time to get into Kotlin programming.
