Create a class named Couple that contains two Person objects. Create a class named Wedding for a wedding planner that includes the date of the wedding, the Couple being married, and a String for the location. Provide constructors for each class that accept parameters for each field, and provide get methods for each field.Create a class Course, which has one field: String courseName Create the constructor, accessor, and mutator for the class. Then, in the main method of this class, create an instance of the class with the name "CST1201". Write an equivalent while statement to replace the following for statement for (int i=2; i<100; i=i+2) { System.out.println(i); }Define the Circle2D class that contains: Two double data fields named x and y that specify the center of the circle with get methods. A data field radius with a get method. A no-arg constructor that creates a default circle with (0, 0) for (x, y) and 1 for radius. A constructor that creates a circle with the specified x, y, and radius. A method getArea() that returns the area of the circle. A method getPerimeter() that returns the perimeter of the circle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this circle. See Figure 10.14(a). A method contains(Circle2D circle) that returns true if the specified circle is inside this circle. See Figure 10.14(b). A method overlaps(Circle2D circle) that returns true if the specified circle overlaps with this circle. See the figure below. Figure (a) A point is inside the circle.

The Rock class contains the following fields: sampleNumber - of type int description - A description of the type of rock (of type String) weight - The weight of the rock in grams (of type double) Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor. This is the code I have, the program does not like at all what I have - import java.util.*; public class DemoRock { public static…

Write a basic WineCase class to represent a case of wine. A WineCase object has four fields: refNo (a unique sequence of letters and digits), description (e.g. "chablis", "white burgundy" or similar), noOfBottles (in the case) and price (the price of the case in pounds). The constructor for the class should be passed suitable arguments to initialise these four fields. Add a selectWineCase() method to the Browser class which allows a browser to choose a case of wine provided that browser is a buyer. This method is passed a WineCase object as a parameter. You should declare a new field wineCase in the Browser class in order to store the case of wine selected. Make the selectWinecase() method print a message to the terminal window about the selection. An example is shown below: Buyer with ID 6732 has selected wine case with reference number LO786, a case of 2018 Pinot…Step 3: Add a basic WineCase class and allow a buyer to select a case of wine to buy.

- Create a class called Invoice in your assignment source package. An Invoice should include four pieces of information as attributes(instance variables) - a part number of type String, a part description of type String, a purchasing quantity of type Int, and a price per item of type double. Your class should have a full constructor that initializes all the four attributes. Provide a set and a get method for each attribute. In addition, provide a method named getInvoiceTotal that calculates the invoice total, purchasing quantity * price per ite, and returns the invoice total. If the quantity is negative, returns 0. Create an test app named InvoiceTest in the same package that demonstrates class Invoice's capabilities.You will create a couple of classes that could be used to create a Text Adventure game. The class will be called "Item" and will represent an item in the game that can be carried and used by a player (such as a weapon or a tool). The Item Class The Item class will have only one property: A string description. The Item class will have exactly 3 methods: There will be a default constructor that takes no parameters. This constructor will give a generic, default description of the Item. There will be a constructor that takes a string parameter, and it will initialize the Item's description based on the parameter. There will be a method called "print" that will print the Item's description to standard output. PLEASE MAKE SURE ITS POSSIBLE TO COMPILE WITH THIS CODE. THANKS. #include "Item.h" #include <iostream> #include <string> using namespace std; int main() { Item sword("Sword of Destiny"); Item potion("Healing Potion"); Item key("Key of Wisdom"); string name; cout…This is the question I am stuck on - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum.
