Hello! I am a student (obviously, haha), and I am confused about how I need to do something in my driver class. I have a text file that I am reading in, then I decided to use a string tokenizer to parse the data. Now, I need to store the data to something, and then I have two other classes that I had to create in accordance with lab specs, and use them to get a specific output. I know the classes don't interact, but once I parse this string, how should I store the data and then call the other classes to use this data to get my output? I can't find an example of what I am trying to do. Which means I obviously don't know wth I am doing, because I am sure there are PLENTY of examples.
input file:
Chocolate Cake,260,3,12,8
Apple Pie,420,15,4,40
Lemon Meringue,80,0,2,11
Expected Output once executed correctly:
Dessert: Chocolate Cake
Cals: 260.0
Fat: 3.0g
Protein: 12.0g
Carbs: 8.0g
Dessert: Apple Pie
Cals: 420.0
Fat: 15.0g
Protein: 4.0g
Carbs: 40.0g
Dessert: Lemon Meringue
Cals: 80.0
Fat: 0.0g
Protein: 2.0g
Carbs: 11.0g
DONE
