Kotlin has been designated as the official programming language for Android development, complementing Java. This blog post explores Kotlin's features, its relationship with Java, and how beginners can effectively learn it.
Welcome back to the Kotlin tutorial series! In this post, we will explore Kotlin, the programming language that has been officially recognized by Google for Android development since its announcement at Google I/O 2017. This tutorial is designed for both beginners and experienced developers looking to enhance their skills.
In 2017, Google announced Kotlin as the official language for Android development. This decision does not mean that Java is being replaced; rather, Kotlin is intended to work alongside Java. Historically, Java was the sole official programming language for Android applications. Now, developers have the option to use Kotlin, which is designed to be more user-friendly and efficient.
Kotlin is known for its simplicity and ease of use, making it an excellent choice for those new to programming. While it is beneficial to have a basic understanding of Java, it is not strictly necessary to start learning Kotlin. However, familiarity with the Java Virtual Machine (JVM) concepts will enhance your understanding of how Kotlin operates.
Kotlin was introduced in 2011 by JetBrains, the same company behind the IntelliJ platform and Android Studio. The collaboration between Google and JetBrains has strengthened Kotlin's position as a preferred language for Android development. Many developers had already begun using Kotlin prior to its official recognition, which contributed to its adoption.
For developers who have been using Java for years, the transition to Kotlin can be seamless. Kotlin allows developers to accomplish tasks with significantly fewer lines of code compared to Java. For instance, a function that may require 10 to 20 lines in Java can often be written in just 5 to 6 lines in Kotlin. This reduction in code not only simplifies development but also minimizes the potential for bugs, as fewer lines of code typically lead to fewer errors.
As of April 25, 2017, the current version of Kotlin is 1.1.2. The language continues to evolve, with new updates expected to introduce additional features. While there are limited books available specifically for Kotlin, the official documentation can be found at kotlinlang.org. This site offers comprehensive tutorials and resources for learners.
This tutorial series is designed with the learner in mind. The only prerequisite is a basic understanding of Java. Each video in the series is kept short, typically under six minutes, to maintain engagement and facilitate better learning. Research from edX indicates that student attention spans are limited, so concise videos are more effective.
