OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

**Programming Exercise: Working with Classes and Objects**

To enhance your understanding of object-oriented programming, please follow the steps below to create and manipulate instances of a class.

1. **Create a Class Named `testRoom`**

Begin by creating a class named `testRoom`. This class will utilize another class, which we will assume exists and operates correctly according to prior instruction or context. The `testRoom` class must include a `main()` method that performs the following actions:

2. **Instantiate Objects**

Within the `main()` method, create two instances of the `Pay` class:
- `Motel Six`: Use the default constructor to initialize this instance.
- `Ramada`: Initialize this instance such that the room price is set to $550.

3. **Modify Object Properties**

Make changes to the properties of the created instances:
- Change the price of the `Motel Six` room to $265.
- Adjust the amenities cost for the `Ramada` to $240.

4. **Calculate Total Costs**

Calculate the total cost for both `Motel Six` and `Ramada` instances. This involves summing up the room price and the cost of amenities.

5. **Display Costs**

Finally, output the following information for both instances (Motel Six and Ramada) with proper labels:
- Standard room fee
- Costs for amenities
- Total cost

This exercise aims to provide a practical application of class creation, object instantiation, property modification, and calculation of totals using basic object-oriented principles.

Java
Part 1: Setting the turtle size when it is instantiated Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following: Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. Add an empty method body. Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE. In the method body of the one-parameter constructor do the following in this order: Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter. Compile the program and fix any…
In python and include doctring: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie that takes a Movie…

The class provided represents a item. Information about a item includes the name of the item and the count of items in inventory (inventory count). When ordering items they are ordered in descending order by the inventory count. If items have the same inventory count then they are ordered in ascending alphabetical order by their name (a-z). Here is an example set of items: 7 Camera 5 Bicycle 5 Lego 5 Robot 3 Tricycle The Item class is missing a required method. Write the missing method in the space provided below. public class Item implements Comparable { private String name; private int count; public Item (String nameIn, int count In) { name name In; count countIn; }
Overriding is useful when a method has the same signature and type as a method in the parent class. O a local variable has the same name as an instance variable. O you want to change the return type of a method. O a method has the same signature as another method in the same class.
