I am currently doing my very first coding project in Java. It is an Ordering System that should enable the customer the following things. First the customer should be able to navigate through the application, select his/her favourite restaurant within Copenhagen, and choose meals from their individual menu lists. Second, each order should be customizable with relation to the order quantity and delivery location. Lastly, the system should assign the closest available biker to pick up the order from the restaurant and deliver the meal to the indicated destination at the defined time.
After much help of @Theresa I tested the programme again, but I can't get the last mile to run. The part where the system should assign the closest available biker to pick up the order from the restaurant does not work. I still feel kind of hopeless, because I haven tried been everything I could
Any other comments, hints or help would be highly appreciated. Thanks a lot in advance.
