- Method Definition:
def sum: A
- Return Type:
It returns the sum of all the elements in the stated iterator.
Example:
// Scala program of sum()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Declaring a iterator val iter = Iterator(2, 4, 5, 6) // Applying sum method val iter1 = iter.sum // Displays output println(iter1) }} |
Output:
17
Here, the sum of all the elements is printed.
Example:
// Scala program of sum()// method // Creating objectobject GfG{ // Main method def main(args:Array[String]) { // Declaring a iterator val iter = Iterator(1.5, 2.3, 3.4) // Applying sum method val iter1 = iter.sum // Displays output println(iter1) }} |
Output:
7.199999999999999
