This project is a Bank Management System implemented in Java, following strong Object-Oriented Programming concepts such as abstraction, inheritance, polymorphism, interface implementation, and encapsulation.

This system allows users to manage various types of bank accounts, perform transactions, calculate interest, and view reports.

• Create different types of bank accounts:

  • Savings Account
  • Current Account
  • Loan Account
  • Salary Account

• Deposit & Withdraw money

• Overdraft handling (Current Account)

• Loan repayment logic

• Interest calculation

• End-of-Day Report

• Transaction history for each account

• Fully menu-driven program

• Java (Core Java)
• OOP Concepts
• UML Design
• Eclipse/VS Code/IntelliJ

Below is the UML diagram representing the full architecture:
