I'm on chapter 9(Inheritance and Polymorphism) of this textbook that teaches java. It's supposed to be a basic program but I am so lost with this. I need to see how this program should be written:

Create Personal Acct and BusinessAcct classes that inherit the Account class presented Chapter 8(Classes and Object Oriented Development). A Personal account requires a minimum balance of $100. If the balance falls below this amount then $2.00 is charged(withdrawn) to the account. A business account requires a minimum balance of $500, otherwise the account is charged $10. Create Client Code to test the classes.

Thanks so much everyone!
