Program to convert Java set of Shorts to a Vector in Scala

Last Updated : 14 Jan, 2020

A java set of Shorts 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 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 Shorts in Java
        val set = new java.util.HashSet[Short]()
        
        // Adding Shorts to the set
        set.add(1000)
        set.add(899)
        set.add(999)
        
        // Converting set to a Vector 
        val vec = set.toVector
        
        // Displays vector
        println(vec)
    
    }
}

Output:

Vector(899, 999, 1000)

Example:2#

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 Shorts in Java
        val set = new java.util.HashSet[Short]()
        
        // Adding Shorts to the set
        set.add(-1000)
        set.add(999)
        set.add(-233)
        
        // Converting set to a Vector 
        val vec= set.toVector
        
        // Displays vector
        println(vec)
        
    }
}

Output:

Vector(-1000, 999, -233)
