Scala Programming: Create a new array taking the middle element from three arrays of length 5
Scala Programming Array Exercise-11 with Solution
Write a Scala program to create a new array taking the middle element from three arrays of length 5.
Sample Solution:
Scala Code:
object Scala_Array {
def test(x: Array[Int], y: Array[Int], z: Array[Int]): Array[Int] = {
if (x.length != 5 || y.length != 5 || z.length != 5) throw new IllegalArgumentException("Array length not matched!")
else Array(x(2), y(2), z(2))
}
def main(args: Array[String]): Unit = {
var result1 = test(Array(1,2,3,4,5),Array(2,3,4,5,6),Array(3,4,5,6,7))
// Print all the array elements
println("New array:")
for ( x <- result1 ) {
print(s"${x}, ")
}
}
}
Sample Output:
New array: 3, 4, 5,

Previous: Write a Scala program to calculate the sum of the last 3 elements of an array of integers. If the array length is less than 3 then return the sum of the array. Return 0 if the array is empty.
Next: Write a Scala program to reverse an array of integer values.
