Question

Please write code in java and comment. Thanks. I would appreciate that.

Fitness Task:
public interface Fitness

• public Muscle [ ] muscleTargeted() A method that returns the muscle that is going to be affected by the fitness. Note that the return type of the method is Muscle. A human body has a finite number of muscle parts that can be affected by fitness exercises. Define an enum datatype called Muscle with the follwoing member values Abs,Back,Biceps,Chest,Arms,Glutes,Shoulders,Triceps,Legs,Cardio
• public String description() a method that returns a short decription of the fitness type.

Anaerobic Task:

(10pts) Anaerobic is a Fitness and we cannot give the actual implementation for the methods muscleTargeted() as we don't know the actual Anaerobic exercise. The descripton() method returns the string Anaerobic means "without oxygen.". Note that Anaerobic is a good candidate to be abstract class.

Define class yoga which are Anaerobic fitness exercises. Use the following table to define the classes. The classes also have:

• @Override public String description() returns the name of the respective classes.

Exercise Type	Muscle affected
Yoga	Triceps,Biceps

public class Profile

Assume the weight is in kgs, height in meters and gender is enum data type called Gender. In addition, this class must contain:

• public Profile(int age, double height, double weight, Gender gender) A constructor which accepts the age,weight, height, and gender.
• provide getters and setters for height , weight and gender.

public class DailyExercise

• public DailyExercise(ArrayList exerciseList, int duration, double calorieTarget, Profile profile) A constructor which accepts the list of exercises, number of minutes to workout and the amount of calories to be burnt.
• public DailyExercise(ArrayList exerciseList, Profile profile) A constructor which sets duration to 1 hour and calorieTarget to 500.
• public void addExercise(Fitness ex) add a new Fitness in the exerciseList.
• public void removeExercise(Fitness ex) removes an Exercise from the exerciseList.If the exercise does not exist, it will leave the exerciseList unchanged.
• public void setExerciseList(ArrayList list) A setter method which sets the exerciseList of the DailyExercise.
• public void setDuration(int duration) A setter method which sets the duration of the DailyExercise.
• public void setCalorieTarget(double target) A setter method which sets the amount of calorie to be burnt of the DailyExercise.
• public void setProfile(Profile profile) A setter method which sets the profile of the user.
• public ArrayList getExerciseList( ) A getter method which returns the exerciseList of the DailyExercise.
• public int getDuration() A getter method which returns the duration of the DailyExercise.
• public double getCalorieTarget() A getter method which returns the amount of calorie to be burnt of the DailyExercise.
• public Profile getProfile() A getter method which returns the profile of the user.
• public Fitness[] getExercises(Muscle[] targetMuscle) - returns an array of Fitness exercises from the exerciseList that fullfills all the target muscle groups (targetMuscle) the user wants to work on for that specific day. The method will return null if there is no exercise that targets all the muscle groups.

public class WeeklyExercise

• public WeeklyExercise(ArrayList exerciseList, int days, double weeklyCalorieTarget, Profile profile) A constructor which accepts the list of daily exercises, number of days to workout per week and the amount of calories to be burnt.
• public WeeklyExercise(ArrayList exerciseList, Profile profile) A constructor which sets number of days to 7 and weeklyCaloryTarget to 3500.
• public void addExercise(Fitness ex) add a Fitness in the exerciseList.
• public void removeExercise(Fitness ex) removes a Fitness from the exerciseList.If the fitness does not exist, it will leave the exerciseList unchanged.
• public void setExerciseList(ArrayList list) . A setter method which sets the exerciseList of the WeeklyExercise.
• public void setDays(int days) A setter method which sets the number of days the user plans to workout for the week.
• public void setWeeklyCalorieTarget(double target) A setter method which sets the amount of calorie to be burnt per week.
• public void setProfile(Profile profile) A setter method which sets the user's profile.
• public ArrayList getExerciseList( ) A getter method which returns the exerciseList of the WeeklyExercise.
• public int getDays() A getter method which returns the number of days the user plans to workout per week.
• public Profile getProfile() A getter method which returns the user's profile.
• public double getWeeklyCalorieTarget() A getter method which returns the amount of calorie to be burnt for the week.
• public ArrayListgetWeeklyExercises(Intensity intensity) a method that returns a list of DailyExercises that the user should do in order to meet the targeted calorie loss. The method evenly distributes the calorie loss over the number of days the user plans to workout. This method accepts the intensity of the exercises.
• public ArrayListgetWeeklyExercises() a method that returns a list of DailyExercises that the user should do in order to meet the targeted calorie loss. Note that the DailyExercise suggessions include the duration (minutes) the user should work out towards the targeted calorie loss.
• public String targetedCalorieLoss(double targetWeight, int withInDays) this method returns the string that contains a suggestion on how to loss the targeted weight within the specified number of days. . If the target weight is greater than the actual weight of the user, the method throws a TargetWeighException. You need to define a TargetWeightException that extends Java's Exception class and displays the string "Only works to lose weight".
