Bank Account System

Create a BankAccount class with attributes like account_number, holder_name, and balance.

Add methods deposit(amount) and withdraw(amount) (prevent negative balance). Create two account objects and perform transactions.

OOP Focus: Class, objects, attributes, methods, and basic encapsulation.
