Program to convert Java list of Integer to an Iterable in Scala

A java list of Integer can be converted to an Iterable in Scala by utilizing toIterable method of Java in Scala. Here, we need to import Scala’s JavaConversions object in order to make this conversions work else an error will occur.
Now, lets see some examples and then discuss how it works in details.
Example:1#

// Scala program to convert Java list
// to an Iterable in Scala

// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating list of Integer in Java
        val list = new java.util.ArrayList[Int]()

        // Adding Integer to the list
        list.add(8)
        list.add(9)
        list.add(10)

        // Converting list to an Iterable
        val iterab= list.toIterable

        // Displays output
        println(iterab)

    }
}

Output:

Buffer(8, 9, 10)

Therefore, a buffer is returned and the elements are present in the order of the stated list and also duplicate elements are not eliminated here.
Example:2#

// Scala program to convert Java list
// to an Iterable in Scala

// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating list of Integer in Java
        val list = new java.util.ArrayList[Int]()

        // Adding Integer to the list
        list.add(3)
        list.add(2)
        list.add(1)

        // Converting list to an Iterable
        val iterab= list.toIterable

        // Displays output
        println(iterab)

    }
}

Output:

Buffer(3, 2, 1)

Here, the stated list is not in proper order so the resultant buffer is also not in proper order.
