How to import a package in Kotlin

Shubham Singh Kshatriya

Overview

A package is a group of related classes, enums, functions, sub-packages, and so on.

To import a package in Kotlin, we use the import keyword, followed by the name of the package that needs to be imported.

Syntax

import package-name

Code example

Let’s see how we import a package in Kotlin, in the following code snippet:

// import package
import kotlin.math.*

fun main() {
    // access method defined in package
    var sqrtOf4 = sqrt(4.0)
    println(sqrtOf4)
}
