}

im trying to extract this matrix and putting into a submatrix but i keep getting 14 on every location of the new matrix... help... but when i go..

  for(int i = row; i < height +row; i++){
            for(int j = col; j < width+col; j++){
                     System.out.printf("%2d" + " " ,data[i][j]);
        }
}

on my for loop. i get exactly the numbers that i want.. help
