In Scala mutable collections, SortedSet isEmpty() method is utilized to test if the SortedSet is empty or not.
Method Definition: def isEmpty: Boolean
Return Type: It returns true if the SortedSet is empty else it returns false.
Example #1:
// Scala program of isEmpty() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedSet val s 1 = SortedSet( 1 , 2 , 3 , 4 , 5 ) // Applying isEmpty method val result = s 1 .isEmpty // Display output println(result) } } |
Output:
false
Example #2:
// Scala program of isEmpty() // method import scala.collection.mutable.SortedSet // Creating object object GfG { // Main method def main(args : Array[String]) { // Creating a SortedSet val s 1 = SortedSet() // Applying isEmpty method val result = s 1 .isEmpty // Display output println(result) } } |
Output:
true
