Example #1:

Scala

// Scala program of mkString() 
// method 
import scala.collection.mutable.SortedSet

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet(121, 2242, 331, 400) 
        
        // Applying mkString method 
        val result = s1.mkString
        
        // Display output
        println(result)
    } 
}

Output:

1213314002242

Example #2:

// Scala program of mkString() 
// method 
import scala.collection.mutable.SortedSet

// Creating object 
object GfG 
{ 

    // Main method 
    def main(args:Array[String]) 
    { 
        // Creating a SortedSet 
        val s1 = SortedSet("Geeks", "Will", "Rule") 
        
        // Applying mkString method 
        val result = s1.mkString
        
        // Display output
