Transaction System (Java OOP Assignment)
A simulation of a bank transaction system built around an interface (TransactionInterface) and three progressively specialized classes:
BaseTransaction — the concrete base class. Stores an amount, date, and auto-generated UUID. Its apply() just logs the transaction without touching the account balance.
DepositTransaction — credits money to a BankAccount. Irreversible by design.
WithdrawalTransaction — debits money, can throw InsufficientFundsException, supports partial withdrawals, and can be reversed via reverse().
InsufficientFundsException — a custom checked exception that carries details about the shortfall.
BankAccount — a simple account with credit() and debit() methods.
