Scala – Read and Print a Matrix

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

Scala code to read and print a matrix using a two-dimensional array

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.
