I will Pay you $ 20.00 by Pay pal if u do this program before 4 today. two hrs left.
Problem:
Program will read a text file to create Food objects which will consist of a food name, a serving size, and a number of calories. A text file is read which contains the calories contained in specific food items. From this data, an array of Food objects will be created and used to populate a combo box for user selection. The Food objects will also be used in calculating the balance calories for a given user on a given day.
User input will be used to create User objects which will be user name, age, gender, height, weight, and Food Diary objects (composition). The Food Diary objects will consist of Date (composition), Food object (composition), number of servings, and a balance. Food Diary objects will consist of the activity on any given day (see text area in sample output screen below). All User objects are saved to a file as objects and can be retrieved on subsequent runs of the program.
The program will calculate the number of calories the user is allowed per day to maintain the user’s current weight (see below for formula to use for this).
BMRMen = 66 + (13.7 * weightPounds/2.2) + (5 * heightInches*2.54) - (6.8 * age)
BMRWomen = 655 + (9.6 * weightPounds/2.2) + (1.8 * heightInches*2.54) - (4.7 * age)
