Object-oriented programmingcreate a program that manages the production of a company. The production of each of the months of the year 2021 is saved, the average production of the year is also stored.Include a method to display all company information.Include at least three public or private type attributes. If they are private don't forget to include the getter and setter methods ONLY for private attributes.Include both default and parameterized constructors.Your program must allowShow all company dataRequest company dataShow the name of the month that had the highest production.Show the name of all the months with production less than the annual average.Identify the methods that are of the class and those that are of the main program.DO NOT forget that attributes, methods, classes, objects and messages are written in English.The MIN and MAX methods must be part of the main program. NOT of the class

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...

A cash processing company has a class called Account used to process transactions: Method/Constructor Description public Account (Client c) public boolean process (Transaction t) constaucts an account using client information processes the next transaction, returning true if transaction was approved, false otherwise Account objects interact with Transaction objects, which have many methods including: Method/Constructor Description returns the value of this transaction in pennies (could be negative, positive or zero) public int value() The company wishes to create a slight modification to the Account class that filters out zero-valued transactions. Design a new class called FilteredAccount whose instances can be used in place of an Account object but which include the extra behavior of not processing transactions with a value of 0. More specifically, the new class should indicate that a zero-valued transaction was approved but shouldn't call the process method in the Account class to...

The Essay class has a default constructor, a constructor with two parameters, and a constructor with three parameters. Declare the following objects: essay1 with no arguments essay2 with essayTitle and essayAuthor as arguments essay3 with essayTitle, essayAuthor, and essayYear as arguments Ex: If the input is Painting Cole 1919, then the output is: Essay: Undefined, Unspecified, 0 Essay: Painting, Cole, 0 Essay: Painting, Cole, 1919 Archive.java public class Archive { publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); StringessayTitle; StringessayAuthor; intessayYear; essayTitle=scnr.next(); essayAuthor=scnr.next(); essayYear=scnr.nextInt(); /* Your code goes here */ essay1.print(); essay2.print(); essay3.print(); } } Essay.java public class Essay { private String title; private String author; private int year; public Essay() { // Default constructor title = "Undefined"; author = "Unspecified"; year = 0; }...

Create a class Person to represent a person according to the following requirements: A person has two attributes: id Add a constructer to initialize all the attributes to specific values. Add all setter and getter methods. Create a class Product to represent a product according to the following requirements: A product has four attributes: a reference number (can’t be changed) a price an owner (is a person) a shopName (is the same for all the products). Add a constructer without parameters to initialize all the attributes to default values (0 for numbers, "" for a string and null for object). Add a second constructer to initialize all the attributes to specific values. Use the keyword "this". Add the method changePrice that change the price of a product. The method must display an error message if the given price is negative. Add a static method changeShopName to change the shop name. Add all the getter methods. The method getOwner must return an owner. Create the class...

Create a Class called Transaction with: instance variables: stock - your stock class type - char -> b or s (buy/sell) quantity - can be fractional price - buy/sell price when - LocalDate constructors: constructor with parameters for stock, type and quantity. - sets the price from the stock price instance variable - sets when from LocalDate getters and setters for each instance variable

Discussion: Advantages of Methods This discussion has 2 parts: What are the advantages of using methods? Name at least 2 advantages and how you benefit from each. List at least 1 scenario you would want to use methods instead of having the code in the main class.

Create a class of Dog, some of the differences you might have listed out maybe breed, age, size, color, etc. Then create characteristics (breed, age, size, color) can form a data member for your object. Then list out the common behaviors of these dogs like sleep, sit, eat, etc. Design the class dogs with objects and methods.

Design a class named octopus that holds attributes for an octopus named weight and color. Include methods to set and get each of these attributes. Create the class diagram and write the class pseudocode that defines the class. Create a small program that declares two octopus objects and set the octopus's name weight and color attributes the program must also output each octopus's name weight and color after they are set. Please write out the pseudocode. I have a hard time with this.
