A. Food Class 1. The food class is defined by the three following properties: name of the item, amount of calories and the weight usually measured in grams. 2. Create a constructor that takes as arguments the name, weight and amount of calories. Initialize the variable accordingly. 3. You will need to retrieve the amount of calories later on. Add the necessary method. 4. A toString method that returns the name of the item and its weight. Sample: 100 grams of rice B. Meal Class 1. The meal class is defined by two properties: a. Name b. An ArrayList of Food objects that represents the food items of that specific meal 2. Create a constructor that takes as argument the name of the meal. Initialize the variables accordingly. 3. Add the following methods to your class: a. addFood method that takes as argument a Food object and has no returned value. The method adds a Food item to the ArrayList of foods. 5 b. removeFood method that takes as argument a Food object and has no returned value. The method removes the Food item form the ArrayList of foods. c. getCalories method that takes no argument and returns the total amount of calories in the meal based on the Food items in that meal. d. A toString method that return a summary of the meal: the name, and food items. Hint: You already defined a method that provides a summary of each food item. Sample Output: Lunch includes: 100 grams of rice 100 grams of grilled chicken 60 grams of bread C. C. Driver Class 1. Prompt the user to enter the information about his “Lunch”. First ask the user about the number of foods he wishes to have. 2. Collect the necessary information about each food item (name, weight, calories). 3. When information about all the food items is collected: a. Print a summary of the meal b. Print the total calories in the meal
