/*
Банкомат
Разберись, как работает программа

Во время тестирования лог содержит следующее:
…..
Добавляем 100, на счету 1100
Добавляем 100, на счету 1200
Тратим 1000, на счету 100
Недостаточно денег
…..

Создан баг:
При списании денег со счета теряются деньги

Найти и исправить ошибку


Требования:
1. Класс BankAccount должен содержать private поле balance типа BigDecimal.
2. Метод deposit(String money) класса BankAccount должен делегировать поведение в метод deposit(BigDecimal money).
3. Метод withdraw(String money) класса BankAccount должен делегировать поведение в метод withdraw(BigDecimal money).
4. В методе withdraw(BigDecimal money), если необходимо, используй synchronized.
5. В методе deposit(BigDecimal money), если необходимо, используй synchronized.
