Scala Mutable SortedSet +() method

  • Last Updated : 26 Mar, 2020

In Scala mutable collections, +() method is utilized to create a new SortedSet with an additional element unless the element is already present.

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

Return Type: It returns a new SortedSet with an additional element unless the element is already present.

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(4, 8, 9, 1, 7
          
        // Applying +() method 
        val result = s1.+(5)
              
        // Display output
        print(result) 
    
Output:
TreeSet(1, 4, 5, 7, 8, 9)

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
          
        // Applying +() method 
        val result = s1.+(100)
              
        // Display output
        print(result)    
    
Output:
TreeSet(1, 12, 23, 41, 43, 72, 100)
