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.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 3 , 1 , 5 , 2 , 4 )
// Print the TreeSet
println(t 1 )
// Applying sum method
val result = t 1 .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.mutable. _
// Creating object object GfG
{ // Main method
def main(args : Array[String])
{
// Creating TreeSet
val t 1 = TreeSet( 3 , 1 , 5 , 7 , 9 )
// Print the TreeSet
println(t 1 )
// Applying sum method
val result = t 1 .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
