Scala TreeSet dropRight() method with example

Last Updated : 02 Nov, 2019

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

Example #1:

Scala

// 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

// 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)
