Banking system using java

The OOP Java Banking System is a console-based (or GUI-based) application developed using Java and Object-Oriented Programming principles. The system simulates basic banking operations such as account creation, deposit, withdrawal, balance inquiry, and transaction history.

The project is designed with core OOP concepts including:

Encapsulation – securing account data using private variables and public methods

Inheritance – creating different account types such as SavingsAccount and CurrentAccount

Polymorphism – handling different account behaviors through common interfaces or base classes

Abstraction – defining general banking operations in abstract classes or interfaces

Main Features:

Create new bank accounts

Login using account number and PIN

Deposit and withdraw money

Different account types with specific rules

Basic error handling and validation
