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

A java Set of characters 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 characters in Java
        val set = new java.util.HashSet[Char]()
          
        // Adding characters to the set
        set.add('a')
        set.add('b')
        set.add('c')
          
        // Converting set to a String
        val str = set.toString
          
        // Displays output
        println(str)
      
    }
}
Output:
[a, b, c]

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 characters in Java
        val set = new java.util.HashSet[Char]()
          
        // Adding characters to the set
        set.add('d')
        set.add('b')
        set.add('c')
          
        // Converting set to a String
        val str = set.toString
          
        // Displays output
        println(str)
          
    }
}
Output:
[b, c, d]

Here, the stated set is not in correct order but the resultant output is in proper order.
