A java set of Strings 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[String]()
set.add( "geeks" )
set.add( "for" )
set.add( "geeks" )
val ind = set.toIndexedSeq
println(ind)
}
}
|
Output:
Vector(geeks, for)
Therefore, an indexed sequence is returned, but duplicate of any string is not displayed.
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 ind = set.toIndexedSeq
println(ind)
}
}
|
Output:
Vector(author, I, am an)
Here, the stated set returns an indexed sequence where, the string with greater length is displayed first and the strings with more number of words are displayed at last.
