Practicing the Java OOP concepts on a Banking operations program

Banking Operations Program

Desafio: Um banco oferece aos seus clientes dois tipos de contas (corrente e poupança), as quais possuem as funcionalidades de depósito, saque e transferência (entre contas da própria instituição).

Scope:

1. User Authentication:

• Users should be able to log in with their username and password.
• Only authenticated users can access banking features.

2. Account Management:

• Users can create different types of accounts, such as savings accounts and checking accounts.
• Each account should have a unique account number.
• Users can deposit and withdraw funds from their accounts.
• Users can check their account balance.
• Users can transfer funds between their accounts or to other users' accounts.

Object-Oriented Concepts

Polymorphism:

• Implement different types of accounts (e.g., savings account, checking account) as subclasses of a common superclass (e.g., Account).
• Use polymorphism to perform operations on accounts without knowing their specific types.

Interfaces:

• Implement these interfaces in concrete classes to provide functionality.

Abstraction:

• Use abstraction to hide the implementation details of account operations from the user interface.
• Define abstract classes or interfaces to represent common behavior across different account types.

Inheritance:

• Utilize inheritance to create specialized account types that inherit common behavior from a base account class.
• For example, a savings account may inherit from a general account class and override methods for interest calculation.
