import a package

• Import classes, objects from other packages

import scala.util

var rnd = new util.Random
println(rnd.nextInt())

import a class/object

• Import classes, objects from other packages

import scala.util.Random

var rnd = new Random
println(rnd.nextInt(1000))

import all

• use specific classes/objects

import scala.util.{Random, Success}

var rnd = new Random
println(rnd.nextInt(1000))

import all

• use _ for importing all

import scala.util._

var rnd = new Random
println(rnd.nextInt(1000))

import a class/object

• Import with alias name

import scala.util.{Random => RandomX}

var rnd = new RandomX
println(rnd.nextInt(1000))

import Hide

• Hide random, import everything
• Random is not imported

import scala.util.{Random => _, _}

//below lines throw error
var rnd = new Random
println(rnd.nextInt(1000))

import scope

• import in scope bountry, -- Random can't be accessed outside scope

def generateRandom : Int = {
    import scala.util.{Random}

    var rnd = new Random
    var n = rnd.nextInt()
    return n;
}
