More Requirements

The requirements describe what each method does. The method to accept a deposit adds an amount (in cents) to the current balance. The current balance can be negative or positive.

The method to process a check subtracts the amount of the check from the current balance. Overdrafts are allowed, so the balance can become negative. However, if the balance is less than $1000.00 before the check is processed, $0.15 is charged for each check.

To simplify the program, assume that all input data is correct (so the methods do not check for errors).

It is time to think about design. The first thing to do is sketch out the class definition:

class CheckingAccount
{
   instance variables

   constructors

   methods

}

The instance variables is where the declarations of variables go.
