Class Diagram:

1. In the above diagram, the multiplicities 1 indicate that it is only one, corresponding to a particular scenario. For example: when we are considering a school, then it is only one, whereas all others like departments, classes, students, and professors can be many.

2. So, 1..* indicates that the school consists of more than one of those class members.

Information: Consider a banking system with 3 classes:  BankAccount, CheckingAccount, and SavingsAccount, that you are to design and write. Have CheckingAccount and SavingsAccount inherit from BankAccount. In BankAccount, you should include an account number, an account balance, a deposit method, a toString method, and an abstract withdraw method. Since deposits work the same way in both child classes, make sure they cannot override it. The constructor should only take an initial deposit and generate a random 5 digit account number. The...

Design You will need to have at least four classes: a parent class, a child class, a component class, and an unrelated class. The component object can be included as a field in any of the other three classes. Think about what each of the classes will represent. What added or modified methods will the child class have? What added fields will the child class have? Where does the component belong? How will the unrelated class interact with the others?...
