Program to convert Java Set to a Traversable in Scala

Last Updated : 02 Dec, 2019

A java Set can be converted to a Traversable collection in Scala by utilizing toTraversable method of Java in Scala. Here, we 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 program to convert Java set  
// 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 set in Java 
        val set = new java.util.HashSet[Int]() 
          
        // Adding integers to the set 
        set.add(9) 
        set.add(10) 
        set.add(11) 
          
        // Converting set to a Traversable  
        val tra= set.toTraversable 
          
        // Displays traversable  
        println(tra) 
      
    } 
} 

Output:

Set(9, 10, 11)

Therefore, a Traversable collection is returned. Here, firstly a set is created where, integer elements are added to it utilizing add method. After that toTraversable method is utilized in order to convert the stated set to a Traversable collection.
Example:2#

// Scala program to convert Java set  
// 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 set in Java 
        val set = new java.util.HashSet[Int]() 
          
        // Adding integers to the set 
        set.add(7) 
        set.add(6) 
        set.add(5) 
          
        // Converting set to a Traversable  
        val tra= set.toTraversable 
          
        // Displays traversable  
        println(tra) 
          
    } 
}
