Last Updated :

A java set of Strings 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#
import scala.collection.JavaConversions._
object GfG
{
def main(args:Array[String])
{
val set = new java.util.HashSet[String]()
set.add("geeks")
set.add("for")
set.add("geeks")
val iterab= set.toIterable
println(iterab)
}
}
|
Here, the duplicate string is eliminated and the resultant output is in proper order as the stated set is also in proper order.
Example:2#
import scala.collection.JavaConversions._
object GfG
{
def main(args:Array[String])
{
val set = new java.util.HashSet[String]()
set.add("i")
set.add("am an")
set.add("author")
val iterab= set.toIterable
println(iterab)
}
}
|
Output:
Set(author, i, am an)
Here, the stated set is not stated in proper order but the resultant output is in proper order. As strings with more number of letters is displayed first and a string with more number of words is displayed at last.
