7 Best IDEs for Kotlin in 2022

Android mobile application development is a growing industry with new mobile apps coming almost daily. It was the time when we did not have many options but code the application right from the scratch for each platform. But, wow with the constant innovation in the technology, we may easily code our own mobile apps quickly and efficiently by using various functions in it.

Kotlin today has become quite an emerging and prevalent language at a contemporary time. The language was released in 2011 and is rising till today. This is the cross-platform and general-purpose modern programming language. Kotlin programming language can be used for android app development. However, before you start using the Kotlin language, it is important to select an IDE where you can write its source code. Here, we will try to reveal some Best IDEs names by which you may understand which is the best IDE for Kotlin.

Which IDE is good for Kotlin and how do you find the right one? There are many editors and IDEs available today that is good for Kotlin programming, but some popular names I recommend include:

  • IntelliJ IDEA
  • Eclipse
  • Android Studio
  • Atom
  • Sublime Text
  • Vim
  • Visual Studio Code

But, before understanding each IDEs in detail, let us know more about them first.

What’s an IDE?

Integrated Development Environment or IDE is the comprehensive solution, which allows the mobile application developers to carry out the software development cycle at a faster pace. The development cycle includes writing, designing, testing, compiling, and debugging a code. For the fast development, it is suggested that you use IDE’s.

7 Best IDEs for Kotlin

1. IntelliJ IDEA

Having an exquisite and clean interface, this IDE specializes in enterprise web & mobile application development with help of Scala, Java, Groovy, Kotlin, and different frameworks for Android app development. Furthermore, detailed documentation will help in the seamless integration that is simple to understand.

Furthermore, multiple plugins are accessible for the IntelliJ IDEA to carry out any task. This framework-based assistance, unobtrusive intelligence, productivity boosters, inspections, and duplicates are offered with the IDE. By using IntelliJ IDE, you may do in-depth Kotlin coding, fast navigation as well as error analysis too.

Community edition in IntelliJ IDEA can easily be accessed free for developing Android and JVM app development, however, in its Ultimate Edition, you can access at the cost for applications.

Kotlin Program to Swap Two Numbers

Here you will learn different ways to swap values of two numbers.

Let’s say our two numbers are a=10 and b=20. So after swapping the values should be a=20 and b=10.

Now we will see how we can implement this in kotlin. We can do this in two ways, with and without using a temp variable.

Method 1: Swap Two Numbers Using Temporary Variable

fun main(args: Array<String>) {

    var a = 10
    var b = 20

    println("Values before swapping\na=$a b=$b")

    var temp = a
    a = b
    b = temp
    
    println("\nValues after swapping\na=$a \nb=$b")
}

Output:

Values before swapping
a=10 b=20

Values after swapping
a=20 
b=10

Method 2: Swap Two Numbers Without Temporary Variable

fun main(args: Array<String>) {

    var a = 10
    var b = 20

    println("Values before swapping\na=$a b=$b")

    a = a+b
    b = a-b
    a = a-b
    
    println("\nValues after swapping\na=$a \nb=$b")
}

Let’s understand how it works. After a = a+b, a holds 30. Then after b = a-b, b holds 10. And finally, after a = a-b, a holds 20.

Comment down below if you have any queries regarding the swapping of two numbers in kotlin.
