Program to convert Java set of Strings to an Iterable in Scala
  • Last Updated : 29 Dec, 2019

A java set of Strings can be converted to an Iterable in Scala by utilizing toIterable 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 program to convert Java set
// to an Iterable 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("geeks")
        set.add("for")
        set.add("geeks")
          
        // Converting set to an Iterable
        val iterab= set.toIterable
          
        // Displays output
        println(iterab)
      
    }
}
Output:
Set(geeks, for)

Here, the duplicate string is eliminated and the resultant output is in proper order as the stated set is also in proper order.
Example:2#




// Scala program to convert Java set
// to an Iterable 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 integers to the set
        set.add("i")
        set.add("am an")
        set.add("author")
          
        // Converting set to an Iterable
        val iterab= set.toIterable
          
        // Displays output
        println(iterab)
      
    }
}
Output:
Set(author, i, am an)

Here, the stated set is not stated in proper order but the resultant output is in proper order. As strings with more number of letters is displayed first and a string with more number of words is displayed at last.
