Can you help me with a sample code for every class(dietitian, customer, gui and main). a dietitian works with an appointment system. The appointments are 30 mins and they work between 08-13 and 14-19. I need a Java GUI class where the dietitian can select new clients and view the time schedule. We already have two classes with the personal information of the dietitian as a Dietitian Class and the personal information of the customers as Customers Class. This JAVA GUI required only using swing and awt. the customer will be selected and added to a time schedule. Also, a Java swing gui class is required where this dietitian can view the information of customers in another class. You can give value to constructor of the dietician and customers as you wish. JAVA
