Create a health Record class for a person. The class should have the following attributes: first name last name date of birth consisting of separate instance variable for cach of month, day and year of birth) height (in m) weight (in kg) Your class should have a constructor that receives all the above attributes. For each attribute, provide set and get methods. The class also should include methods that: 1. computeAge : calculate and return the user's age in years to compute age use: 2020 minus year of birth) 2. compute MHR: calculate and return the maximum heart rate. According to the American Heart Association (AHA) (www.americanheart.org presenter.jhtml?identifier 4736), the formula for calculating your maximum heart rate in beats per minute is 220 minus your age in years 3. computeB MI: calculate and return the user's body mass index (BMI). The formula for calculating BMI is Write a festDrive class which includes your main function. In your main function: 1. Ask the user to enter his/her information as shown in the sample output below 2. Calculate and print the user's maximum heart rate 3. Calculate and print the user's BMI 4. Print the BMI category according to the following rule: BMI VALUES Underweight: less than 18.5 Normal: between 18.5 and 24.9 Overweight: between 25 and 29.9 Obese: 30 or greater Sample output (green color represents user's input): Enter your first name: Manar Enter your last name: Khalid Enter your date of birth: Day: 1 Month: 1 Year: 2000 Enter your height in meter: 1.46 Enter your weight in kg: 56 Manar's age is 19 Your maximum heart rate is 201 Your BMI is 26.27 --> Overweight
