Question
1. Create a Eclipse project named [your pitt id]_MenuManager
2. Create a package edu.pitt.is17.[your pitt id].menumanager
3. Implement the following classes as represented in the class diagrams.
Methods and constructors are explained below. Classes Entree, Side, Salad and Dessert are all straightforward and the same, representing the parts of a menu. Class Menu contains one object of each of the other classes (Entree, Side, Salad and Dessert) and a name.
Entree:
- name: String
- description: String
- calories: Int
------------------------(Line divider)
+ Entree(name: String, desc, String, cal : Int)
Side:
- name: String
- description: String
- calories: Int
-----------------------(Line divider)
+ Side(name : String, desc: String, cal : int)
Salad:
- name : String
- description: String
- calories: Int
---------------------(line divider)
+ Salad(name : String, desc: String, cal : int)
Dessert:
- name : String
- description: String
- calories: Int
---------------------(line divider)
+ Dessert(name : String, desc: String, cal : int)
