Hello, I have to Design a class name Rectangle to represent a rectangle. The class contains: Two data fields named width and height A constructor that creates a rectangle with the specified width and height The default values are 1 and 2 for the width and height, respectively. A method named getArea() that returns the area of this rectangle A method named getPerimeter() that returns the perimeter Draw the UML diagram for the class, and then implement the class. Write a test program called TestRectangle that creates two Rectangle objects—one with width 4 and height 40 and the other with width 3.4 and height 35.7. Display the width, height, area, and perimeter of each rectangle in this order.

I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
I need help! Modify the class named FormLetterWriter that includes two overloaded methods named displaySalutation(). The first method takes one String parameter that represents a customer’s last name, and it displays the salutation Dear Mr. or Ms. followed by the last name. The second method accepts two String parameters that represent a first and last name, and it displays the greeting Dear followed by the first name, a space, and the last name. After each salutation, display the rest of a short business letter using the displayLetter method: Thank you for your recent order. public class FormLetterWriter {public static void main(String[] args) {displaySalutation("Kelly");displayLetter();displaySalutation("Christy", "Johnson");displayLetter();} public static void displaySalutation(String lastName) {// Write your code here} public static void displaySalutation(String firstName, String lastName) {// Write your code here}public static void displayLetter() {// Write your code here}}
Currently, there are two draw rectangle methods in the DoodleController class. Since two different turtles need to draw a rectangle, create a draw rectangle method in the DoodleTurtle class that will take the width and height of the rectangle as parameters and draw a rectangle of the specified size. The size will be the number of steps by the turtle. With the new method introduced, the calls to drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle can be replaced with a call to the turtle’s drawRectangle method passing in the desired size of the rectangle. Refactor the DoodleController accordingly. Note: When you are done with the refactoring the drawRectangleWithLittleTurtle and drawRectangleWithBigTurtle method in the DoodleController need to be deleted. After this refactoring, do not move on until you verify the program works as it did before.
For this lab task, you will work with classes and objects. Create a class named text that works similar to the built-in string class. You will need to define a constructor that can be used to initialize objects of this new class with some literal text. Next, define three methods: to_upper() that will convert all characters to uppercase, reverse() that will reverse the text and length() that will return the length of the text. After you have completed this part, copy the following mainfunction to your code and check if the implementation is correct. int main() { text sample = "This is a sample text"; cout << sample.to_upper(); // This should display "THIS IS A SAMPLE TEXT" cout << endl;cout << sample.reverse(); // This should display "txet elpmas a si sihT"cout << endl; cout << sample.length(); // This should display 21 }
In Java, Create a class Rectangle with double attributes length and width. The default constructor should set these attributes to 1. Provide methods that calculate the rectangle's perimeter and area, as well as accessors and mutators for both data fields. The mutator methods for length and width should verify that the number being passed in is larger than 0.0 and less than 20.0 -- if it doesn't fit those criteria, the value of the field should not be changed.Write a Driver class in the same file to test your Rectangle class. It should prompt the user to enter a length and width of a rectangle, and then print out the area and perimeter of the rectangle. (Use the mutators to set the length and width of the rectangle, not the constructor.)
For the 'The Chicken class' on the app intelliJ in java. The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…
I need help with creating a Java program described in the image below: 9.26 LAB: Artwork label (classes/constructors) Given main(), define the Artist class (in file Artist.java) with constructors to initialize an artist's information, get methods, and a printInfo() method. The default constructor should initialize the artist's name to "unknown" and the years of birth and death to -1. printInfo() displays "Artist:", then a space, then the artist's name, then another space, then the birth and death dates in one of three formats: (XXXX to YYYY) if both the birth and death years are nonnegative (XXXX to present) if the birth year is nonnegative and the death year is negative (unknown) otherwise Define the Artwork class (in file Artwork.java) with constructors to initialize an artwork's information, get methods, and a printInfo() method. The default constructor should initialize the title to "unknown", the year created to -1. printInfo() displays an artist's information by calling the…
I have provided you with 3 interfaces (HasLegs, HasWings, and BreathesUnderwater) and a Tester class. I want you to create 6 new classes: • 2 that implement HasLegs • 2 that implement HasWings • 2 that implement BreathesUnderwater For each of the classes, you will have to implement the methods that the interface dictates. In addition, override toString so that it prints out a simple message describing what the object is. See the example output of my implementation below for an idea how to do that. The Tester class creates 3 ArrayLists, one for each interface. It also loops through each ArrayList and prints out its contents using toString and the interface methods. In between those two chunks of code, you’ll see a //TODO: comment. It is there that I want you to create one object for each of the 6 classes you created and add that object to the appropriate ArrayList. Once you have done all that, you should be able to run your program and see output like the following: I am a table. I have…
How to create a class in java that contains get and set methods for the double variables x,y,height,width where x and y represent the center point of your rectangle and width and height epresent the width and height of your rectangle and a constructor that has x, y, width, and height input parameters, for example If the x or y input parameters are less than 0.0, set them to be 0.0 and If the width or height input parameters are less than 1.0, set them to be 1.0 (the constructor must contain if statements), then test your class by create a class with a main method that creates instances of your class, calling all the constructors and method?
This is for pygame Text Class The Text class inherits from Drawable and it will be used to display the player’s score. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class

a. Carly's Catering provides meals for parties and special events. In Chapters 3 and 4, you created an Event class for the company. Now, make the following changes to the class: Currently, the class contains a field that holds the price for an Event. Now add another field that holds the price per guest, and add a public method to return its value. Currently, the class contains a constant for the price per guest. Replace that field with two fields—a lower price per guest that is $32, and a higher price per guest that is $35. Add a new method named isLargeEvent() that returns true if the number of guests is 50 or greater and otherwise returns false. Modify the method that sets the number of guests so that a large Event (more than 50 guests) uses the lower price per guest to set the new pricePerGuest field and calculate the total Event price. A small Event uses the higher price. Save the file as Event.java. b. In Chapter 4, you modified the EventDemo class to demonstrate two Event…
