    Default Re: Dont know how to recorrect

    how to set that customer record with vacant
    What is a vacant vehicle?
    Is there a Customer class? That would be a logical place to save data for a customer.
    If not, what is a customer record?

    You have a variable named vacant in the Rent class. You have code that sets its value.
    Can you explain what you are trying to do?
