1. Design a Java JFood class for a food which implements both cloneable and comparable interfaces  The class should have the following private member variables: mId: an integer that holds the food ID mName: a string that holds the food name mQuantity: an integer that holds quantity of servings of food mCalory: a double that holds calory of one serving of food mIngredients: an array of String that holds the names of all ingredients and its size is three  and the class should have the following public member functions: default constructor: initializes the product to some default one constructor #2: accepts id, name, quantity, calory and ingredients as arguments.  The method should set these values to the appropriate instance variables setFood: accepts quantity, calory and ingredients as arguments.   The method should set the arguments to the appropriate instance variables. Please note ingredients need be set as deep copy.  Five respective get functions to retrieve the five instance…

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate.   Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)   ClassRegistration -…
