Scala program to print the size of the array

Program/Source Code:

The source code to print the size of the array is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to print the
// size of the array

object Sample {

  def main(args: Array[String]) {
    var arr = Array(1, 2, 3, 4, 5);

    printf("Size of array: %d\n", arr.size);
  }
}

Output:

Size of array: 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 arr that contains 5 integer elements. Then we used the size() method to get the size of an array. After that, we printed the result on the console screen.
