Scala immutable TreeSet dropRight() method

In Scala immutable 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 program of dropRight()
// method

// Import TreeSet
import scala.collection.immutable._

// 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.immutable._

// 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)
