Guys, this is another one. I suppose there is no compile error! Try it. Dont ask any question! programme:- import java.util.*; public class MagicOddSquare { public static void main(String[] args) { Scanner input = new Scanner (System.in); int[][] magicSquare; boolean isAcceptableNumber = false; int size = -1; //only accept odd numbers while (isAcceptableNumber == false) { System.out. println(Enter in size of square: ); String sizeText = input.nextLine(); size = Integer.parseInt (sizeText); if (size % 2 == 0) { System.out. println(The size must be an odd number); isAcceptableNumber = false; } else { isAcceptableNumber = true; } } magicSquare = createOddSquare (size); displaySquare (magicSquare); } public static int [][] createOddSquare (int size) { int[][] magicSq = new int[size][size]; int row = 0; int column = size/2; int lastRow = row; int lastColumn = column; int matrixSize = size*size; magicSq[row] [column]= 1; for (int k=2;k < matrixSize+1;k++) { //check if we need to wrap to opposite row if (row - 1 < 0) { row = size-1; } else { row--; } //check if we need to wrap to opposite column if (column + 1 == size) { column = 0; } else { column++; } //if this position isnt empty then go back to where we //started and move one row down if (magicSq [row][column] == 0) { magicSq[row] [column] = k; } else { row = lastRow; column = lastColumn; if (row + 1 == size) { row=0; } else { row++; } magicSq[row] [column] = k; } lastRow = row; lastColumn= column; } return magicSq; } public static void displaySquare(int[][] magicSq) { int magicConstant = 0; for (int j=0;j< (magicSq.length);j++) { for (int k=0;k
