🤓 Study Prompts

Use the following questions to guide your exploration and learning! 🗺

• Run the main method on the Main class, what is it doing? What is being outputted to the console?

• Look at the DodgyBankAccount, this class is not well-encapsulated. Can you note down the problems with how the class is designed, and the ways it is being misused?

• Compare and contrast the DodgyBankAccount and the SecureBankAccount, how is the SecureBankAccount different to the DodgyBankAccount? How is it designed to prevent it from being misused? Are there instances of better method names for clearer abstraction?
