a developer want to develop a simple take away restaurant order service using java.The system read from a file containing information about the restaurants(such as the name,place and menu).The system then allows the user to login into the system. Once the user is successfully login,a user is able to see the menu.A user then can use the system to place an order(s) from the particular restaurant. The system then alerts the restaurant. Eventually,the restaurant prepares the ordered menu and delivers them to the customer. please help me to solve this problem.
