### Edit it { #edit-it }

It's a very simple program.

But now imagine that you were writing it from scratch.

At some point you would have started the definition of the function, you had the parameters ready...

                badWordService.store(entity);
                suggestHelper.storeAllBadWords(false);

        return redirectByParam(AdminGeneralAction.class, "notificationTo", form.notificationTo);

### Отредактируем пример { #edit-it }

Это очень простая программа.

А теперь представьте, что вы пишете её с нуля.

В какой-то момент вы бы начали определение функции, у вас были бы готовы параметры...
