Scala Programming: Calculate the average value of an array of elements
Scala Programming Array Exercise-3 with Solution
Write a Scala program to calculate the average value of an array of element.
Sample Solution:
Scala Code:
object Scala_Array {
def main(args: Array[String]): Unit = {
var nums = Array(1, 2, 3, 4, 5, 6)
println("Original Array elements:")
// Print all the array elements
for ( x <- nums ) {
print(s"${x}, ")
}
//Sum using for loop
var total = 0.0;
for ( i <- 0 to (nums.length - 1)) {
total += nums(i);
}
println(s"\nAverage value of the array elements is: ${total/nums.length}");
}
}
Sample Output:
Original Array elements: 1, 2, 3, 4, 5, 6, Average value of the array elements is: 3.5
