Scala Mutable SortedSet sum() method

In Scala mutable collections, sum() method is utilized to find the sum of all the elements of the SortedSet.

Method Definition: def sum: A

Return Type: It returns the sum of all the elements of the SortedSet.

Example #1:

// Scala program of sum()
// method
import scala.collection.mutable.SortedSet


// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(40, 10, 2, 3)

        // Applying sum method
        val result = s1.sum

        // Display output
        println(result)
    }
}

Output:

55

Example #2:

// Scala program of sum()
// method
import scala.collection.mutable.SortedSet


// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {
        // Creating a SortedSet
        val s1 = SortedSet(2, 6, 5, 8)

        // Applying sum method
        val result = s1.sum

        // Display output
        println(result)
    }
}

Output:
