Hands-On Object-Oriented Programming with Kotlin

How to access a function

There are a couple of ways to access a package-level function. One way to do this is by using a package name with each function. This method has already been used in the previous example:

Util.hello()

The second way to access a package-level function is to import each function explicitly by using the import keyword:

import Util.hellofun main(args: Array<String>) {   hello()   println("Power Function")   println(Util.myPow(5.0,3.0))} 

Notice that by adding import Util.hello, Kotlin allows us to use the hello function without using a package name with it. The third and most common way to import a package is with the wildcard:

import Util.*fun main(args: Array<String>) {    hello()    println("Power Function") println(myPow(5.0,3.0)) ...
