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

A java list of Strings can be converted to an Iterable in Scala by utilizing toIterable method of Java in Scala. Here, you 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 Strings in Java
        val list = new java.util.ArrayList[String]()

        // Adding Strings to the list
        list.add("geeks")
        list.add("for")
        list.add("geeks")

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

        // Displays output
        println(iterab)

    }
}

Output:

Buffer(geeks, for, geeks)

Therefore, a buffer is returned and the elements are present in the order of the stated list and 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 Strings in Java
        val list = new java.util.ArrayList[String]()

        // Adding Strings to the list
        list.add("I")
        list.add("am an")
        list.add("author")

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

        // Displays output
        println(iterab)

    }
}

Output:

Buffer(I, am an, author)

Here, the stated list is not in proper order so the resultant output is also not in proper order. That is, the strings with more number of words are not displayed in the last, they are returned as stated in the list in the form of buffer.
