I have created two class Customer class Stock class Both classes contain a rentstock() method What I was hoping to achieve was to get the customer(person) to write out information and if stock is available to show as available. For rent .........Yes And if it is not available to switch to say no. I tried using a Boolean but it is only true or false would anyone have suggestions on how to get item to show as yes or no when an item has been rented out rather than true or false
