Создал калькулятор счёта, не без помощи знающих товарищей. Заметил что при вводе числа с копейками в формате 500.1 выдаёт ошибку, а если писать 500,1 то работает, то есть через запятую работает нормально. Один из вариантов решения нашёл scanner.useLocale(Locale.US); но это что-то непонятное поэтому не стал.
