Understanding "What is Kotlin" in Just 5 Minutes



Creating an android-based application can use the Java and Kotlin programming languages. Generally the android tutorial at Badoystudio uses the Java programming language.
Now in this article we will discuss briefly about what Kotlin is. Check out more now!

What is Kotlin?

Kotlin is a modern programming language developed by JetBrains (the company that developed the IDEA IntelliJ IDE and Android Studio) to create multiplatform applications.
Currently Google has supported Kotlin to become one of the official languages used to build android applications in addition to the Java and C ++ programming languages.

Kotlin Features

Some features and advantages of kotlin are:

Open Source: Kotlin is distributed under the Apache License, Version 2.0. The compiler (Kotlin compiler), IntelliJ IDEA plugins, and java libraries are all open source.
Easy To Learn: Kotlin Programming Language is easy to learn. It is influenced by Java, Scala, Groovy, C #, JavaScript and Gosu Learning Kotlin is easy to do if you are familiar with one of these programming languages. It's easy to learn if you know Java.
Safe: Kotlin guarantees that every syntax we write in the compilation process can prevent possible errors, for example being able to prevent NullPointerExceptions when we write code using the Java language.
Consice and Expressive: The compilation process and complexity when coding using java will be reduced when using kotlin.
Interoperable With Java and Android: Kotlin can read the old code or library that we use when coding in the Java language and vice versa.

Some Companies Use Kotlin

Many large companies have used the Kotlin programming language to develop their applications, including:
·         Uber: is the first online transportation company in the world. So it is not Gojek or Grab that first sparked a business idea connecting the vehicle owner to the passenger.
·         Pinterest: is a virtual pinboard service where we can upload photos that are included in certain categories to be customized according to their name.
·         Netflix: is a company providing digital streaming media services, especially films from the United States.
·         Coursera: is an online learning media course originating from the United States.
·         Evernote: is an application that we can use to make or save certain notes on a smartphone or computer.
·         and others

Kotlin in the Future

In the future Kotlin will be used for the development of:
·         Cross-platform Game Development: Developing games that can be used on various platforms such as Windows, Mac OS, and Linux.
·         Cross-platform Mobile Application Development: Develop mobile applications that can run on various mobile OS such as Android, iOS, and others.
·         Server-side and Microservices
·         Data Analysis and Machine Learning
·         Embedded System: Arduino / Raspberry Pi to professional controllers directly.

Example of Kotlin Programming Coding

Here are some examples of coding that use the Kotlin programming language.
  • Hello World 
fun main() {
println("Hello World!")
}
  • String 
val name = "Anne"
val yearOfBirth = 1985
val yearNow = 2018
val message = "$name is ${yearNow - yearOfBirth} years old"
  • Loop 
val names = listOf("Anne", "Peter", "Jeff")
for (name in names) {
println(name)
}

Learning Kotlin

There are several ways to learn the Kotlin programming language, including online, using the command line, or an IDE that supports Kotlin.

To learn Offline we can use the Android Studio IDE or the Intel IDE. If you want to learn from the basics it's good to learn on the Intellij IDE. But if you want to immediately feel making an android application using Kotlin just use Android Studio.

Closing

From the description above, we can conclude that Kotlin has very good prospects for software development, whether mobile, web, or others. So, Ready for an adventure with kotlin?

Badoystudio will update the Kotlin learning tutorial with Intellij IDEA (category: Kotlin Basic) and also with android studio (category: Kotlin Android) which is updated on Monday and Thursday.
