Shubham Singh KshatriyaOverview
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)
}Importing a package in Kotlin
