The 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.immutable.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.immutable.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
