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 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) } } |
