Kotlin Tutorial for Beginners: Kotlin Programming

Kotlin Tutorial: Kotlin is an open-source statically typed programming language that runs on Java Virtual Machine (JVM). It combines Object Oriented Programming (OOPs) and functional programming in unrestricted, self-sufficient, and distinctive platforms. It also allows the twinning of functionalities by miniature codes.

Kotlin is a statically-typed programming language, developed by JetBrains. If you have basic knowledge of Java, you will be able to learn Kotlin in no time. This Kotlin tutorial is designed for beginners so you would be able to understand Kotlin programming even if you do not know Java.

Kotlin and Java are interoperable which means you can use them together in a Project as well as you can re-write a Java code in Kotlin efficiently. The syntax of Kotlin is more concise than Java. In this tutorial, you will learn why to use Kotlin, what are its advantages of it, and several guides on the various topics of Kotlin.

History of Kotlin

Here, are important landmarks from the history of Kotlin:

YearEvent
2016Kotlin v1.0 was launched
2017Announcement of Google on the first-class support of kotlin in android
2018Kotlin v1.2 comes with add on distributing codes between JVM and JavaScript
2019Google announced Kotlin as its preferred programming language for Android Application Developers
2021On September 20, 2021, Kotlin v1.5.31 was launched.

Features of Kotlin

Concise: Kotlin is more concise than Java, you would need to write approx 40% fewer lines of code compared to Java.

Interoperability: Kotlin is highly interoperable with Java. You would not face any difficulty using Kotlin in a Java project.

Open Source: Kotlin is an open-source programming language.

Trust: You can trust kotlin as this is developed by the popular and well-known company JetBrains. JetBrains is known for creating several development tools. The popular Java IDE IntelliJ IDEA is developed by this same company.

Feature-rich: Kotlin provides several advanced features such as Operator overloading, Lambda expressions, string templates, etc.

Easy: Kotlin is easy to learn programming language. If you have came from a Java background, you would find it easy to learn Kotlin.

Less error-prone: As I mentioned in the beginning, Kotlin is a statically-typed programming language, which makes you able to catch errors at compile time as Statically typed programming languages do type checking at compile time.

Reasons for using Kotlin

Here, are some important reasons why Kotlin is used widely:

  • Kotlin is a statically-typed language that is very easy to read and write.
  • Kotlin programs do not require semicolons in their program. This makes the code easy and more readable.
  • This language allows the exchange and use of information from Java in various ways. Moreover, Java and Kotlin code can co-exist in the same project.
  • Kotlin’s type system is aimed to eliminate NullPointerException from the code.
  • It’ll take you less time to write new code in Kotlin. It’s even easier to deploy kotlin code and to maintain it at scale.
