Bank Management System

This is a simple Bank Management System implemented in Java, demonstrating key Object-Oriented Programming (OOP) principles such as Abstraction, Encapsulation, Inheritance, and Polymorphism.

Features

  • Account Class (Abstraction & Encapsulation)

    • Private properties: accountNumber, balance, ownerName
    • Public methods: deposit(), withdraw(), getBalance()
    • Protected method: setBalance() to allow controlled access for subclasses

  • SavingsAccount (Inheritance)

    • Adds interestRate
    • Method applyInterest() to apply interest on balance

  • CurrentAccount (Inheritance)

    • Adds overdraftLimit
    • Method setOverdraftLimit() to configure overdraft
    • Overrides withdraw() to allow overdraft within limits

  • Bank Class (Polymorphism)

    • Manages multiple accounts
    • Allows deposits, withdrawals, and balance checking for any account type

Technologies Used

  • Java
  • OOP Principles
