A Door Class A computer game usually has many different objects that can be seen and manipulated. One typical object is a door. Whether a player runs through a castle, attacks the forces of an evil empire, or places furniture in a room, a door often comes into play. Implement a Door class as described below as well as a TestDoor class that instantiates three Door objects labeled “Enter,” “Exit,” and “Treasure.” The “Enter” door should be left unlocked and opened. The “Exit” door should be left closed and locked. The “Treasure” door should be left open but locked. A Door class A Door object can • display an inscription, • be either open or closed, and • be either locked or unlocked. Here are some rules about how Door’s work. • Once the writing on a Door is set, it cannot be changed. • You may open a Door if and only if it is unlocked and closed. • You may close a Door if and only if it is open. • You may lock a Door if and only if it is unlocked, and unlock a Door if…

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…

Assume method testQuestion() is a method in the Purchase class. Assume the Purchase class has a constructor that has parameters of name, groupCount, groupPrice, and numberBought. public Purchase testQuestion(Purchase p1, int newX) { newX = 20; this.setName("green beans"); p1.setName("corn"); Purchase p2 = new Purchase("broccoli", 5, 4.50, 10); return p2; } Referring to the above method, list the output that would be printed by Sysyem.out.println() when the following PurchaseDemo2 is executed. public class PurchaseDemo2 { public static void main(String[] args) { Purchase tomsPurchase = new Purchase("squash",4,3.50,6 ); Purchase jillsPurchase = new Purchase("carrot",8,1.99,4 ); Purchase billsPurchase;…
In Python, #Create a basket class, which has a class/static attribute pricelist (string/float dictionary - you can hardcode this) #The constructor should set the name to the name passed as a parameter and initialise the contents (empty) #You should provide an addItem method taking product,quantity which adds this to the contents #and a getQuantity method taking a product, which returns the relevant quantity
1. Create a class called Plant with the data member plant name and color. 2. Create a child class called Tree with data member tree name, tree number and color. Inherit all the properties and behaviors from the base class to the child class. 3. Find the total number of times, character ‘a’ available in the plant name and tree name and display the method name as compare. 4. Use display method in both the classes to display“I am Plant” in parent class, and “I am Tree” in child class with all inputs needs to be displayed. Note: Get all the inputs through scanner class.
What is the purpose of a constructor? It creates an array of data values associated with an object. It prints all of the information about our object. It returns all data members from an object back to the main method. It allows us to set our own default values when we create an object. in java
