A java set of characters can be converted to a Vector in Scala by utilizing toVector 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#
Scala
Scala
// Scala program to convert Java set
// to a Vector 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 characters in Java
val set = new java.util.HashSet[Char]()
// Adding characters to the set
set.add('a')
set.add('b')
set.add('c')
// Converting set to a Vector
val vec= set.toVector
// Displays vector
println(vec)
}
}
// Scala program to convert Java set// to a Vector in Scala// Importing Scala's JavaConversions objectimport scala.collection.JavaConversions._// Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating set of characters in Java val set = new java.util.HashSet[Char]() // Adding characters to the set set.add('a') set.add('b') set.add('c') // Converting set to a Vector val vec= set.toVector // Displays vector println(vec) }}
Output:
Therefore, the resultant output is in same order as stated in the above list and the duplicates are also deleted.
Example:2#
Vector(a, b, c)
// Scala program to convert Java set
// to a Vector 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 characters in Java
val set = new java.util.HashSet[Char]()
// Adding characters to the set
set.add('c')
set.add('a')
set.add('b')
// Converting set to a Vector
val vec = set.toVector
// Displays vector
println(vec)
}
}
// Scala program to convert Java set// to a Vector in Scala// Importing Scala's JavaConversions objectimport scala.collection.JavaConversions._// Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Creating set of characters in Java val set = new java.util.HashSet[Char]() // Adding characters to the set set.add('c') set.add('a') set.add('b') // Converting set to a Vector val vec = set.toVector // Displays vector println(vec) }}
Output:
Here, the stated characters are not stated in proper order but the resultant output is in proper order.
Vector(a, b, c)
