(The Rectangle class) Following the example of the Circle class in Section 8.2,design a class named Rectangle to represent a rectangle. The class contains:■ Two double data fields named width and height that specify the width andheight of the rectangle. The default values are 1 for both width and height.■ A no-arg constructor that creates a default rectangle.■ A constructor that creates a rectangle with the specified width and height.■ 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 testprogram that creates two Rectangle objects—one with width 4 and height 40and the other with width 3.5 and height 35.9. Display the width, height, area,and perimeter of each rectangle in this order.
Design a class named MyPoint to represent a point withx- and y-coordinates. The class contains:■■ The data fields x and y that represent the coordinates with getter methods.■■ A no-arg constructor that creates a point (0, 0).■■ A constructor that constructs a point with specified coordinates.■■ A method named distance that returns the distance from this point to aspecified point of the MyPoint type.■■ A method named distance that returns the distance from this point toanother point with specified x- and y-coordinates.■■ A static method named distance that returns the distance from two MyPointobjects.Draw the UML diagram for the class then implement the class. Write a testprogram that creates the two points (0, 0) and (10, 30.5) and displays the distancebetween them.
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.)
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…
Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the reference of any child class object. That…

Display the width, height, area, and perimeter of each rectangle in this order.
Create a class named Lease with fields that hold an apartment tenant’s name, apartmentnumber, monthly rent amount, and term of the lease in months. Include a constructor thatinitializes the name to “XXX”, the apartment number to 0, the rent to 1000, and the term to12. Also include methods to get and set each of the fields. Include a nonstatic methodnamed addPetFee() that adds $10 to the monthly rent value and calls a static methodnamed explainPetPolicy() that explains the pet fee. Save the class asLeaseYourlastname.java. Replace ‘Yourlastname’ with your real last name.b) Create a class named TestLease whose main() method declares four Lease objects. Call agetData() method three times. Within the method, prompt a user for values for each fieldfor a Lease, and return a Lease object to the main() method where it is assigned to one ofmain()’s Lease objects. Do not prompt the user for values for the fourth Lease object, but letit continue to hold the default values. Then, in main(), pass…
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); }
Following the example of the Rectangle class of Chapter 9 Exercise 1, design a class named Cuboid to represent a cuboid. The class contains: Three data fields named length, width, and height. A constructor that creates a cuboid with the specified length, width, and height. A method named getVolume() that returns the volume of this cuboid. Then, please create an object mycuboid = Cuboid (2, 3, 4), and invoke getVolume to print the volume of mycuboid.

Create a class named Student that has fields for an ID number, numberof credit hours earned, and number of points earned. (For example,many schools compute grade point averages based on a scale of 4, so athree-credit-hour class in which a student earns an A is worth 12 points.)Include methods to assign values to all fields. A Student also has a field forgrade point average. Include a method to compute the grade point averagefield by dividing points by credit hours earned. Write methods to display thevalues in each Student field. Save this class as Student.java.b. Write a class named ShowStudent that instantiates a Student object from theclass you created and assign values to its fields. Compute the Student gradepoint average, and then display all the values associated with the Student.Save the application as ShowStudent.java.c. Create a constructor for the Student class you created. The constructor shouldinitialize each Student’s ID number to 9999, his or her points earned to 12,…
