In Scala TreeSet class, the dropRight() method is utilized to drop the last ā€˜nā€™ elements of the TreeSet.
Method Definition: def dropRight(n: Int): TreeSet[A] Return Type: It returns a new TreeSet that consists of all the elements except the last ā€˜nā€™ elements.
Example #1:
// Scala program of dropRight() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9
          
        // Print the TreeSet
        println(t1
          
        // Applying dropRight() method  
        val result = t1.dropRight(2)
          
        // Displays output 
        println("Queue after using dropRight(2) method: " + result)
          
    

                    
Output:
TreeSet(2, 4, 6, 7, 8, 9)
Queue after using dropRight(2) method: TreeSet(2, 4, 6, 7)
Example #2:
// Scala program of dropRight() 
// method 
  
// Import TreeSet
import scala.collection.mutable._
  
// Creating object 
object GfG 
  
    // Main method 
    def main(args:Array[String]) 
    
      
        // Creating TreeSet
        val t1 = TreeSet(2, 4, 6, 7, 8, 9
          
        // Print the TreeSet
        println(t1
          
        // Applying dropRight() method  
        val result = t1.dropRight(4)
          
        // Displays output 
        println("Queue after using dropRight(4) method: " + result)
          
    

                    
Output:
TreeSet(2, 4, 6, 7, 8, 9)
Queue after using dropRight(4) method: TreeSet(2, 4)
