In this lab report, I will detail the development and testing of a simple Java program designed to demonstrate object-oriented programming principles. The program’s primary requirement was to create a class representing a basic bank account with functionalities such as deposit, withdrawal, and balance inquiry. The project aimed to reinforce understanding of class design, method implementation, and object manipulation within a Java environment. Analysis and Design The core approach involved defining a class named BankAccount, which encapsulates private data members such as accountNumber and balance. The class provides public methods for deposit, withdraw, and retrieving the account balance. Additionally, a main class was created to instantiate objects of BankAccount and invoke its methods. This design adhered to encapsulation principles by restricting direct access to data members and using accessor/mutator methods. The design structure comprised the following classes and functions: BankAccount: class with private attributes, constructor, and public methods. Methods include deposit(double amount), withdraw(double amount), and getBalance(). The main class BankApplication creates an account object and tests all functionalities. This modular approach allowed for clear separation of concerns and easier testing. Testing and Results The program successfully met all lab requirements, demonstrated through a series of test cases. I devised several scenarios to validate each functionality: Case Description Test Data Expected Result Actual Result 1 Deposit funds Deposit $200 into new account Balance should increase by $200 Confirmed with screenshot; balance increased to $200 2 Withdraw funds within balance Withdraw $50 from account with $200 Balance should decrease to $150 Confirmed; balance decreased to $150 3 Attempt to overdraw Withdraw $300 from account with $150 Withdrawal rejected, balance remains unchanged Confirmed; message displayed, balance still $150 4 Balance enquir

Case	Description	Test Data	Expected Result	Actual Result
1	Deposit funds	Deposit $200 into new account	Balance should increase by $200	Confirmed with screenshot; balance increased to $200
2	Withdraw funds within balance	Withdraw $50 from account with $200	Balance should decrease to $150	Confirmed; balance decreased to $150
3	Attempt to overdraw	Withdraw $300 from account with $150	Withdrawal rejected, balance remains unchanged	Confirmed; message displayed, balance still $150
4	Balance enquiry	Check balance after transactions	Reflect current balance accurately	Confirmed; displayed balance as expected
