Instructions

In today's lab test, you will be making a prototype till system for a new Dublin winebar called Cafe Rubis that's located on 9 Parliament St. Come and check it out sometime.

• Here is a video of the sketch you will be making today:

  

• Start with a blank sketch. Set the drawing window size to be 800 x 600.

• Name the sketch CafeRubis and commit it to a new, public git repository called CafeRubis under your own GitHub account.

• Put your name and student number into the sketch comments.

• Download this CSV file to the data folder of your sketch folder. The file contains data on the products that Cafe Rubis sells.

• Create a class called Product with a field for name, of type String and a field for price of type float.

• Write a constructor on the Product class that takes a TableRow as a parameter and assigns the fields in the class from the appropriate columns in the TableRow.

• Declare two global ArrayLists of Product objects and call them products and bill.

• Write a function called loadData that loads the data from the file and populates the products ArrayList.Call this from setup.

• Write a function called printProducts that prints the contents of the ArrayList after it has been loaded. You should make a toString method on the Product class to help you do this. Call this from setup after you load the data to make sure the file gets loaded correctly.

• Write a function called displayProducts that displays the product menu that can be seen on the left side of the screen. You can use the function nf to format the price to two decimal places. You can use the function textAlign to align text to the left or right. You should write your code so that the menu gets displayed correctly even if the screen was to change size or if more products were added.

• Write code for the mousePressed function that allows the user to click on a product and have it added to the bill ArrayList.

• Write code for a function called displayBill that draws the bill to the screen as per the video.

Submit the URL of your git repository here. You can also upload a zip file to Webcourses as a backup I'll check webcourses if I have problems with your git repository.
