Help is needed quickly

Modify the class FitnessExperiment class so that it uses polymorphism to: (i) display the properties of each object in a FitnessExperiment, and (ii) identify any StepsFitnessTracker, HeartRateFitnessTracker and DistanceFitnessTracker objects that are equal. Here we are trying to identify those cases where a user mistake might have been made during the initialisation of the FitnessExperiment object (e.g. the data for the same tracker being introduced twice). Those situations should be flagged to the person leading the experiment to verify if the error was genuine or if the object was really the same object. The place were this code should be added is in bold
