Chapter 6.4, Problem 35STQ
Consider the class Species in Listing 5.19 of Chapter 5. It has a method called setSpecies that sets the name, population, and growth rate of a species Could this class have another method setSpecies that has only one parameter for the name of the species and that sets both the population and the growth rate to zero? If so give the definition of this other method named setSpecies.

Solve using OOP in Java.
Write in python and please include docstring. Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address.
Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary.
For example, it…

This method should facilitate the addition of custom cars to the inventory. The method should take two parameters: a car model and its price. Implement this method to ensure that the inventory is updated accordingly. Instantiate a new object of the car inventory, naming it 'Auto Emporium,' utilizing the extended class with the newly added 'add_car' method. Your next step is to add three distinct custom cars to 'AutoEmporium'-for example, "Sleek Sedan,' 'Sporty Convertible,' and 'Luxury SUV Assign varying prices to each of these cars. To conclude, utilize the 'display_inventory method to showcase the updated information about 'AutoEmporium." Verify that the output includes details about the newly added custom cars, ensuring that the prices are accurately reflected.

It would be better if the Demon class's getDamage() function could print the name of the species. Taking this a step further, it would be even better if we didn't have to repeat the cout statement "The <whatever> attacks for ?? points!" in every class's getDamage() function. It would be better if that cout statement could occur just once, in the Creature class's getDamage() function.

- By using JAVAarrow_forwardCreate a TestCard project with a TestCard class and a Card class. Data members for the Card class should be two numeric values representing the suit of the Card and the card's number. The Card class also has a constructor and methods for setting and getting the card information. See UML model. In the TestCard class within main(), deal two cards at a time by constructing two card objects. One card is the user's. The other is the computer's. Show both cards. Add a point to whoever had the higher card. Show who won the trick and the score. Scores don't change if a tie. Keep dealing until user wants to quit or 26 pairs have been dealt. UML for Card class -suit: int the number that corresponds to the suit of the card. 0 Hearts, 1 Diamonds, 2 Clubs, 3 Spades -value: int the value of the card.

In this simulation, a virtual "ant" moves about a two-dimensional square matrix, whose spaces can be designated white or black, according to the rules below: If the ant is on a white space, it will turn right 90 degrees relative to the directions it is facing, move forward one step, and change the space it left to black. If the ant is on a black space, it will turn left 90 degrees relative to the directions it is facing, move forward one step, and change the space it left to white. When the ant hits the edge of the board and is going to go out of the bounds, wrap the board around so the ant will appear on the other side. The matrix is initially composed of all white spaces. The user will specify the size of the square matrix. The user will also specify the number of steps that the ant will move and the starting location and direction of the ant. After the simulation, the final board with the ant position will be displayed to…arrow_forward
