Scala immutable TreeSet sum() method

In Scala immutable TreeSet class the sum() method is utilized to return the sum of all the elements of the TreeSet.

Method Definition: def sum: A

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

Example #1:

// Scala program of sum()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 2, 4)

        // Print the TreeSet
        println(t1)

        // Applying sum method
        val result = t1.sum

        // Displays output
        print("Sum of all the elements of the TreeSet: " + result)

    }
}

Output:

TreeSet(1, 2, 3, 4, 5)
Sum of all the elements of the TreeSet: 15

Example #2:

// Scala program of sum()
// method

// Import TreeSet
import scala.collection.immutable._

// Creating object
object GfG
{

    // Main method
    def main(args:Array[String])
    {

        // Creating TreeSet
        val t1 = TreeSet(3, 1, 5, 7, 9)

        // Print the TreeSet
        println(t1)

        // Applying sum method
        val result = t1.sum

        // Displays output
        print("Sum of all the elements of the TreeSet: " + result)

    }
}

Output:

TreeSet(1, 3, 5, 7, 9)
Sum of all the elements of the TreeSet: 25
