Scala Mutable SortedSet isEmpty() method

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 s1 = SortedSet(1, 2, 3, 4, 5)

        // Applying isEmpty method
        val result = s1.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 s1 = SortedSet()

        // Applying isEmpty method
        val result = s1.isEmpty

        // Display output
        println(result)
    }
}

Output:

true
