* Model the class inheritance hierarchy: Account, CheckingAccount,
SavingAccount, and SuperSavingAccount.
* Model the Customer class
* Think about the most important attributes and methods for each class.
* Explain the relationships between the different classes.
* Return the class diagram as part of the solution!
Ok, I'm confused here.
If Account is the main class, what was that about inheritance hierarchy?
You're never extending any class, other than Object, every time.
Are you sure you're not supposed to have an abstract class called Account and have either three subclasses (Checking, Savings, and SuperSavings), or have two subclasses and have SuperSavings be a subclass of Savings?
Also, you seem to have name being a char variable yet reading it in as a String.
name = input.nextLine();
