Scala Programming: Sum values of an given array
Scala Programming Array Exercise-1 with Solution
Write a Scala program to sum values of an given array.
Sample Solution:
Scala Code:
object Scala_Array {
def main(args: Array[String]): Unit = {
var nums = Array(1.2, 1.7, 1.12, 1.16, 1.81, 1.99)
println("Original Array elements:")
// Print all the array elements
for ( x <- nums ) {
print(s"${x}, ")
}
println("\nUsing sum():")
val result = nums.sum
println(s"Result: ${result}");
println("\nUsing for loop:")
var total = 0.0;
for ( i <- 0 to (nums.length - 1)) {
total += nums(i);
}
println(s"Result: ${total}");
}
}
Sample Output:
Original Array elements: 1.2, 1.7, 1.12, 1.16, 1.81, 1.99, Using sum(): Result: 8.98 Using for loop: Result: 8.98
