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

A java Set of Strings can be converted to a String in Scala by utilizing toString 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 String 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 a String
        val str = set.toString
          
        // Displays output
        println(str)
          
    }
}
Output:
[geeks, for]

Here, the duplicate elements are eliminated and the resultant order of the elements in set is same as stated above.
Example:2#




// Scala program to convert Java set 
// to a String 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 an")
        set.add("author")
          
        // Converting set to a String
        val str = set.toString
          
        // Displays output
        println(str)
          
    }
}
Output:
[author, I, am an]

Here, in the resultant output the strings of more length are displayed first and the strings with more words are displayed at last.
