A java list of bytes can be converted to a Traversable collection in Scala by utilizing toTraversable method of Java in Scala. Here, you need to import Scala’s JavaConversions object in order to make this conversions work.
Now, lets see some examples and then discuss how it works in details.
Example:1#
Scala
Scala
// Scala program to convert Java list
// to a Traversable 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 bytes in Java
val list = new java.util.ArrayList[Byte]()
// Adding bytes to the list
list.add(121)
list.add(111)
list.add(125)
// Converting list to a Traversable
val tra= list.toTraversable
// Displays traversable
println(tra)
}
}
// Scala program to convert Java list // to a Traversable in Scala// Importing Scala's JavaConversions objectimport scala.collection.JavaConversions._// Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating list of bytes in Java val list = new java.util.ArrayList[Byte]() // Adding bytes to the list list.add(121) list.add(111) list.add(125) // Converting list to a Traversable val tra= list.toTraversable // Displays traversable println(tra) }}
Output:
Example:2#
Buffer(121, 111, 125)
// Scala program to convert Java list
// to a Traversable 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 bytes in Java
val list = new java.util.ArrayList[Byte]()
// Adding bytes to the list
list.add(-122)
list.add(-126)
list.add(-100)
// Converting list to a Traversable
val tra= list.toTraversable
// Displays traversable
println(tra)
}
}

Output:
Buffer(-122, -126, -100)
