            field.setAccessible(true);
            try {
                System.out.print(field.getName() + ":"
                            + field.get(object) + "\t");
            } catch (IllegalArgumentException e) {
                    e.printStackTrace();
            } catch (IllegalAccessException e) {
                    e.printStackTrace();
