Scala program to read and print MATRIX using a two-dimensional array

Program/Source Code:

The source code to read and print MATRIX using a two-dimensional array is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

// Scala program to read and print matrix 
// using two-dimensional array

import scala.util.control.Breaks._

object Sample {
  def main(args: Array[String]) {
    var TwoDArr = Array.ofDim[Int](2, 2)
    var i: Int = 0
    var j: Int = 0

    printf("Enter elements of MATRIX:\n")
    i = 0;
    while (i < 2) {
      j = 0;
      while (j < 2) {
        printf("ELEMENT(%d)(%d): ", i, j);
        TwoDArr(i)(j) = scala.io.StdIn.readInt();
        j = j + 1;
      }
      i = i + 1;
    }

    printf("MATRIX:\n")
    i = 0;
    while (i < 2) {
      j = 0;
      while (j < 2) {
        printf("%d ", TwoDArr(i)(j));
        j = j + 1;
      }
      i = i + 1;
      println();
    }
  }
}

Output:

Enter elements of MATRIX:
ELEMENT(0)(0): 10
ELEMENT(0)(1): 20
ELEMENT(1)(0): 30
ELEMENT(1)(1): 40
MATRIX:
10 20 
30 40

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 a 2X2 matrix using a two-dimensional array and then we read and print the elements of the matrix on the console screen.
