Java array_name[0].length function bug?

Question

char[][] board = {
            {'#','#','#','-','@','-','#','#','#'},
            {'#','#','-','@','@','@','-','#','#'},
            {'#','-','@','@','-','@','@','-','#'},
            {'-','@','@','@','@','@','@','@','-'}};

System.out.println(String.format("Rows: %o, Columns: %o", board.length, board[0].length));

For some reason, Java outputs 11 columns. Appreciate any help.

9

Use %d, not %o. %o will present the result in Octal. 11 in Octal is 9 in Decimal.

Thank you! Looks like I need a refresh on format specifiers
