Lab 13a – Exam 3 – Introduction to Programming

Part I

Write a class named MenuItem that models a restaurant menu item. Include the following:

- Fields for the menu item’s name (String), number of calories (int), and price (double).
- A constructor that sets all 3 fields using data passed into the constructor.
  - - Do not include data validation in the constructor.
- Getters and setters for each of the fields.
  - - Do not include data validation in the setters.
- Override the toString() method and return a string containing the name, number of calories, and price, all separated by commas.
- Override the equals() method. Two menu items are considered equal if they have the same name.

Part III

Write a class named Exam3 that satisfies the following.

- The class has a method named printMenu that takes an array of MenuItem elements as an argument and prints to the screen the name, number of calories, and price of each item in the array.

- The class has a main method that when run:
  - Reads the data in menu.txt, and for each menu item in the file creates an instance of the MenuItem class and stores the reference to the instance in an array named menuItems.
  - Prints the menu items stored in the array named menuItems to the screen by calling printMenu.
  - Iterates, using a for-loop, over the array named menuItems and prints to the screen the name, a dash (-), and the price of each menu items in the array that has fewer than 700 calories, with each items on a separate line.
