In Scala TreeSet class, the drop() method is utilized to drop the first ‘n’ elements of the TreeSet.

Method Definition: def drop(n: Int): TreeSet[A]

Return Type: It returns a new TreeSet with all the elements except the first ‘n’ ones.

Example #1:




// Scala program of drop() 
// 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 drop() method  
        val result = t1.drop(2)
          
        // Displays output 
        println("TreeSet after using drop(2) method: " + result)
          
    
Output:



TreeSet(2, 4, 6, 7, 8, 9)
TreeSet after using drop(2) method: TreeSet(6, 7, 8, 9)

Example #2:




// Scala program of drop() 
// 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 drop() method  
        val result = t1.drop(3)
          
        // Displays output 
        println("TreeSet after using drop(3) method: " + result)
          
    
Output:
TreeSet(2, 4, 6, 7, 8, 9)
TreeSet after using drop(3) method: TreeSet(7, 8, 9)
