A java set of characters can be converted to an Indexed Sequence in Scala by utilizing toIndexedSeq 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#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Char]()
set.add( 'c' )
set.add( 'd' )
set.add( 'e' )
val ind = set.toIndexedSeq
println(ind)
}
}
|
Therefore, an indexed sequence is returned.
Example:2#
import scala.collection.JavaConversions. _
object GfG
{
def main(args : Array[String])
{
val set = new java.util.HashSet[Char]()
set.add( 'b' )
set.add( 'c' )
set.add( 'a' )
val ind = set.toIndexedSeq
println(ind)
}
}

Here, the stated set is not stated in proper order but the resultant output is in proper order.
