/* Знания - сила!
1. В методе sort написать компаратор для Stock:
1.1. Первичная сортировка по name в алфавитном порядке
1.2. Вторичная сортировка по дате без учета часов, минут, секунд (сверху самые новые), потом по прибыли от положительных к отрицательным
... open 125,64 and last 126,74 - тут прибыль = 126,74-125,64
... open 125,64 and last 123,43 - тут прибыль = 123,43-125,64
2. Разобраться с *Format-ами и исправить IllegalArgumentException. Подсказка - это одна строчка.
Пример вывода:
Fake Apple Inc.   AAPL | 17-11-2025 open 125,64 and last 123,43
Fake Oracle Corporation   ORCL | 21-08-1989 closed 0,15
