Scala program to get the last N number of elements from the array

Program/Source Code:

The source code to get the last N number of elements from the array is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to get the last N number
// of elements from array

object Sample {
  def main(args: Array[String]) {
    var arr1 = Array(1, 2, 3, 4, 5);
    var arr2 = arr1.takeRight(3);

    var i: Int = 0;

    printf("Elements of arr2\n");
    while (i < arr2.length) {
      printf("%d ", arr2(i));
      i = i + 1;
    }
    println();
  }
}

Output:

Elements of arr2
3 4 5

Explanation:

In the above program, we used an object-oriented approach to create the program. We created an object Sample, and we defined main() function. The main() function is the entry point for the program.

In the main() function, we created an array arr1 that contains 5 integer elements. Then we used the takeRight() method to get the last 3 elements from array arr1 and assigned them to the array arr2. After that, we printed the result on the console screen.
