In Scala mutable collection, ++() method is utilized to add elements of one SortedSet to another SortedSet.

Method Definition: def ++(elems: A): SortedSet[A]

Return Type: It returns a new TreeSet containing elements of both the SortedSets.

Example #1:




// Scala program of ++() method  
import scala.collection.mutable.SortedSet 
   
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
        // Creating a SortedSet 
        val s1 = SortedSet(1, 3, 5
          
        val s2 = SortedSet(2, 4, 6)
          
        // Applying ++() method 
        val result = s1 ++ s2
              
        // Display output
        print(result) 
          
    


Output:

TreeSet(1, 2, 3, 4, 5, 6)

Example #2:




// Scala program of ++() method  
import scala.collection.mutable.SortedSet 
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
        // Creating a SortedSet 
        val s1 = SortedSet(41, 12, 23, 43, 1, 72
          
        val s2 = SortedSet(1, 100, 5, 12, 23)
          
        // Applying ++() method 
        val result = s1 ++ s2
              
        // Display output
        print(result)   
          
    


Output:

TreeSet(1, 5, 12, 23, 41, 43, 72, 100)
