Define a constructor on the simpy class that takes a parameter of type list[float].Its purpose is to initialize the values attribute of the
newly constructed simpy object to the argument passed in.
Once your constructor is properly implemented, you expect to see [1.0, 1.0, 1.0, 1.0, 1.0] printed when evaluating the cell below.
ones = Simpy([1., 1., 1., 1., 1.])
print(ones.values)

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 andDistanceFitnessTracker objects that are equal. Here we are trying to identify thosecases where a user mistake might have been made during the initialisation of theFitnessExperiment 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 wasgenuine or if the object was really the same object.
The area where the code needs to be implemeted will be in bold
We need to write a method that prints duplicates
FitnessExperiment.java
public class FitnessExperiment {FitnessTracker[] fitnessTrackers;public static void main(String[] args) {FitnessTracker[] trackers = {new StepsFitnessTracker("steps", new Steps(230)),new StepsFitnessTracker("steps2", new Steps(150)),new…
Start with this class declaration:
class Student { int sId; String name; double gpa;}
Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects
- based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa.
Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).

You need a separate try/catch block for each kind of error you are screening. One try block can be used to handle many different types of errors raised by Python, but will jump to the except block at the first infraction detected (skipping any potential problems in the remainder/below the infraction detected).arrow_forward

- Can you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"arrow_forwardQuestion 2: Recall and apply the concepts of object oriented programming (Java).(i)Create a generic class with a type parameter that simulates drawing an item randomly out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to draw an item out of an empty box, it should return null. Write a main method that tests your class.arrow_forwardGive me a code example where you can decouple the classes with the help of Interface? II.
