The class Buildinghas 2 attributes: materialUsed and surfaceArea which are of type String and double respectively. The constructor of the class initialises all variables. The class Building also has accessor and mutator (Set and Get) methods for all variables and a method price that calculates and displays the building’s price as per the table below: Surface area price Less or equal to 100 square meters 1000/ square meters Greater than 1500 square meters 1200/square meters Implement the class Building. The class Houseinherits all of the above variables and has another variable noOfStorey which is of type int. House has a constructor that initialises noOfStorey, materialUsed and surfaceArea. The class also has an accessor method for noOfStorey and a method PrintDetails that displays the house details. Implement the class House. Implement a class Construct, with a main method, that will ask the user to input the,number of storey, material used and surface area. The program should then display details of the house and its price. (Use the scanner class for input)

The class "Car" has the following attributes: plate (String), mark (String), model (String), year (int), km (int).Write a constructor method for the "Car" class that takes values as parameters for all these attributes.
You are required to build a class JewelleryItem. A jewellery Item has a type (string) , price (float),material (string), daysToGo (int).These attributes represent the type i.e ‘ear ring’, necklace, finger ring etc. The material can be gold,silver, plastic etc. The daysToGo attribute represents the number of days it will remain fit for use.1. You are required to provide the following parameterized constructors JewelleryItem(string type, float price, string material, int daysToGo) Jewlleryitem(string type, float price, int daysToGo) // the material will get “gold” as default JewelleryItem(string type, float price) //the material defaults to gold and daysToGo defaults to100.2. Now provide getters for each of the attributes above but setters for only price, daysToGo3. Provide a function/method makeUse(). This function represents the use of this item for one daywhich reduces the daysToGo by 1. This function returns true if the daysToGo is greater than 1 andfalse otherwise. This means…
In Java Programming, 2 class needs a no-arg constructor and a constructor that initializes all fields with data (The ProductionWorker class constructor should receive data for the Employee class fields as well). I need help to create a method within the Employee and ProductionWorker classes called displayInfo. (displayInfo accepts no arguments and returns void). To display the data for each constructor, the demonstration class will call the subclass displayInfo method and it will call the superclass displayInfo method. User input is not required for the demonstration class. Have a class named "Employee" with the following fields: - Employee Name - Employee Number in format XXX-L, X = digit w/ range 0-9 & L = letter w/ range A-M. - Hire Date Then one or more constructors and the appropriate accessor and mutator methods for the class. Also, another class named "ProductionWorker" that extends "Employee" class. The "ProductionWorker" class should have the following fields to hold…
this is for a python class 9.12 LAB: Product class In main.py define the Product class that will manage product inventory. Product class has three attributes: a product code, the product's price, and the number count of product in inventory. Implement the following methods: A constructor with 3 parameters that sets all 3 attributes to the value in the 3 parameters set_code(self, code) - set the product code (i.e. SKU234) to parameter code get_code(self) - return the product code set_price(self, price) - set the price to parameter price get_price(self) - return the price set_count(self, count) - set the number of items in inventory to parameter count get_count(self) - return the count add_inventory(self, amt) - increase inventory by parameter amt sell_inventory(self, amt) - decrease inventory by parameter amt Ex. If a new Product object is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is: Name: Apple Price: 0.40 Count: 3 Ex. If 10…
The Room Carpet ClassPart (1) Create a class called RoomCarpet that has three private instance variables: room length and width infoot (double) and carpet cost per square foot (double). Additionally, the class should have:(a) A constructor that takes room length, room width and carpet cost per square foot. The constructor setsthe class variables to these values and in case any of these values is negative, set its instance variable tozero.(b) A mutator method (set) and an accessor method (get) for the carpet cost variable only.(c) A method getArea that returns the area of the room. The area of the room is computed by multiplying theroom’s length by the room’s width.(d) A method getTotalCost that returns the total cost of the carpet. The total cost is computed by multiplyingthe room area by the carpet cost per square foot.Part (2) Write a Java application that asks the user to enter the length and width of a room and the costper square foot of the carpeting. Create an object from…

using jave: Create the a Person class with the following: Class Variables:String firstname String lastname int birthmonth int birthday int birthyear String ssn (All variables above should be private) Constructor The main constructor should take in all values and assign them to their respective private class variables MethodsCreate a public getters and setters for firstname and lastname and SSN getFirstname getLastname setFirstname setLastname Create a public getter method called getBirthdate, which will return a String composed of their birthday in month/day/year format. For example, if birthmonth=3, birthday=22, birthyear=2000, it should return the String "3/22/2000" Create a public method called verifySSN that takes in a String parameter and returns a boolean. It will check the parameter against the person's SSN and return true or false based on whether they match.

Given the following code for the base class Ship write another class that inherits from Ship called SpaceShip. Spaceship should have a field to store forwardLasers(an integer) and aftMineDispensers (another integer). You should provide a constructor that includes forwardLasers as an argument. You should have another constructor that includes both forwardLasers and aftMineDispensers as arguments. You should provide appropriate accessors and mutators. You should include a toString() method that prints out the forwardLasers and aftMineDispensers as well as the information from the super class toString(). Here is the code for the base class Ship. public class Ship { private String name; // Ship name private String yearBuilt; // Year it was built public Ship(String n, String y) { name = n; yearBuilt = y; } public void setName(String n) { name = n; } public void setYearBuilt(String y) { yearBuilt = y; } public String getName() { return…
The Rockford Daily Clarion wants you to design a class named Issue. Fields include the issue number, the total number of advertisements sold in each issue, and total advertising revenue. Include get and set statements for each field. Include a static method that displays the newspaper's motto, (i.e., Everything you need to know) Include three overloaded constructors as follows. A default constructor that sets the issue number to 1 and the other fields to 0. A constructor that allows you to pass values for all three fields. A constructor that allows you to pass an issue number and a number of advertisements sold but sets the advertising revenue at $50 per ad. Create a class diagram and write the pseudocode that defines the class. Design an application that declares three Issue objects using a different constructor version with each object. Display each Issue's values and then display the motto.
Design a class named PhoneCall with four fields: two strings that hold the 10-digit phone numbers that originated and received the call, and two numeric fields that hold the length of the call in minutes and the cost of the call. Include a constructor that sets the phone numbers to Xs and the numeric fields to 0. Include get and set methods for the phone number and call length fields, but do not include a set method for the cost field. When the call length is set, calculate the cost of the call at three cents per minute for the first 10 minutes, and two cents per subsequent minute. Create the class diagram and write the pseudocode that defines the class. Design an application that declares three PhoneCalls. Set the length of one PhoneCall to 10 minutes, another to 11 minutes, and allow the third object to use the default value supplied by the constructor. Then, display each PhoneCall's values. Create a child class named InternationalPhoneCall that inherits from PhoneCall. Override…
