Scala Program: Calculating the sum of elements in a set

Last update on December 21 2024 10:27:30 (UTC/GMT +8 hours)

Write a Scala program to create a set and find the sum of all elements in the set.

Sample Solution:

Scala Code:

object SumOfElementsSetExample {
  def main(args: Array[String]): Unit = {
    // Create a set
    val nums = Set(10, 20, 30, 40, 50)

    // Print the set
    println("Set: " + nums)

    // Find the sum of all elements in the set
    val sum = nums.sum

    // Print the sum
    println("Sum of elements: " + sum)
  }
}

Sample Output:

Set: HashSet(10, 20, 50, 40, 30)
Sum of elements: 150

Explanation:

In the above exercise,

• First, we create a set "nums" with the elements 10, 20, 30, 40, and 50.
• To find the sum of all elements in the set, we use the sum method, which returns the sum of all elements in the set.
• In the program, we find the sum of all elements in the set by using the line val sum = set.sum.
• Finally, we print the set and the sum of all elements.
