Question: Need some help starting off this Java program dealing with Magic Squares. I need to modify this code somehow so that it will read in

Need some help starting off this Java program dealing with Magic Squares. I need to modify this code somehow so that it will read in an appropriately sized 2-d array of integers. So, if the file specifies that the array is of size 6, create a 6x6 array. The first integer in the file specifies the number of the rows and the number of the columns. As an example, say the first file looks like this:

3

4 9 2
3 5 7
8 1 6

import java.util.Scanner; import java.io.File;

public class MagicSquare { private static Scanner input = new Scanner ( System.in ); public static void main ( String args [] ) { try { Scanner keyboard = new Scanner ( System.in ); System.out.println ( " Enter input filename: " ); String inFile; inFile = keyboard.next();

File file = new File ( inFile ); Scanner input = new Scanner ( file );

int first = input.nextInt(); final int ROWS = first; final int COLS = first; int[][] square = new int[ROWS][COLS]; while ( input.hasNext() ) { int v = input.nextInt(); for ( int r = 0; r < square.length; r++ ) { square[r][c] = v; for ( int c = 0; c < square.length; c++ ) square[r][c] = v; } } System.out.println ( first );

} catch ( Exception ex ) { System.out.println ( "An error has occurred!" ); ex.printStackTrace(); } } }
