A java set of bytes 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#
Scala
Scala
// Scala program to convert Java set
// to an Indexed Sequence in Scala
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating set of bytes in Java
val set = new java.util.HashSet[Byte]()
// Adding bytes to the set
set.add(121)
set.add(35)
set.add(126)
// Converting set to an Indexed Sequence
val ind = set.toIndexedSeq
// Displays Indexed Sequence
println(ind)
}
}
Output:
Example:2#
Vector(35, 121, 126)
// Scala program to convert Java set
// to an Indexed Sequence in Scala
// Importing Scala's JavaConversions object
import scala.collection.JavaConversions._
// Creating object
object GfG
{
// Main method
def main(args:Array[String])
{
// Creating set of bytes in Java
val set = new java.util.HashSet[Byte]()
// Adding bytes to the set
set.add(-125)
set.add(-10)
set.add(-126)
// Converting set to an Indexed Sequence
val ind = set.toIndexedSeq
// Displays Indexed Sequence
println(ind)
}
}
Output:
Vector(-10, -125, -126)
