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?
