Program to convert Java Set of strings to a Traversable in Scala
  • Last Updated : 03 Jan, 2020

A java Set of strings 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#

filter_none

code

// 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 of Strings in Java
        val set = new java.util.HashSet[String]()
          
        // Adding Strings to the set
        set.add("i")
        set.add("am")
        set.add("good")
          
        // Converting set to a Traversable 
        val tra = set.toTraversable
          
        // Displays traversable 
        println(tra)
      
    }
}

Output:

Set(i, am, good)

Here, the stated output is in same order as stated in the given set.
Example:2#

        // Adding Strings to the set
        set.add("i")
        set.add("am a")
        set.add("girl")
          
        // Converting set to a Traversable 
        val tra= set.toTraversable
          
        // Displays traversable 
        println(tra)
      
    }
}

Output:

Set(am a, i, girl)

Here, the strings with more number of words are displayed first and strings of greater length are displayed at last.
