Lesson Plan: Designing a Simple Banking System in Java

Objective: To teach college students how to design a simple banking system in Java, including opening accounts, depositing money, withdrawing money, and freezing accounts.

Materials: - Computer with Java programming software installed - Internet access - Projector and screen for displaying code and examples - Handouts with code snippets and instructions

Introduction: - Explain the importance of designing a banking system in Java, as it is a common task for software developers. - Discuss the basic features of a banking system, such as opening accounts, depositing money, withdrawing money, and freezing accounts. - Introduce the concept of object-oriented programming and how it can be used to design a banking system.

Body: 1. Creating a Bank class - Explain how to create a Bank class that will hold all the accounts and transactions. - Demonstrate how to create a constructor for the Bank class and how to initialize the accounts array.

1. Creating an Account class - Explain how to create an Account class that will hold the account information and transactions. - Demonstrate how to create a constructor for the Account class and how to initialize the account balance.

2. Opening an account - Explain how to create a method in the Bank class that will allow users to open a new account. - Demonstrate how to prompt the user for their name and initial deposit, create a new Account object, and add it to the accounts array.

3. Depositing money - Explain how to create a method in the Account class that will allow users to deposit money into their account. - Demonstrate how to prompt the user for the deposit amount and add it to the account balance.

4. Withdrawing money - Explain how to create a method in the Account class that will allow users to withdraw money from their account. - Demonstrate how to check if the account has enough balance, prompt the user for the withdrawal amount, and subtract it from the account balance.

5. Freezing an account - Explain how to create a method in the Account class that will allow users to freeze their account. - Demonstrate how to set a boolean flag in the Account object to indicate that the account is frozen.

Conclusion: - Review the key concepts covered in the lesson, including creating classes, methods, and objects. - Encourage students to experiment with the code and add additional features to the banking system. - Provide resources for further learning, such as online tutorials and books on Java programming.
