Create a class called Rectangle that has the following attributes: Rectangle (pointOne,pointTwo,pointThree,pointFour) getArea() - Double getPerimeter() - Double toString() - String Rectangle pointOne - Point pointTwo-Point pointThree - Point pointFour Point Notes: getArea() and getPerimeter() will return the appropriate values based on standard calculations. In the Rectangle constructor, you should calculate to verify the points passed in form an actual rectangle. If not you should alert the user.

Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.
Rectangle is an object that represents a specific shape. Analyze the concept and identify the data members and methods that should be included in Rectangle class.
Modified Circle class and test file: Add a new attribute for color (or any other new attribute) Add get/set methods for this new instance variable, including data validation in set method (assuming background is black, i.e. circle color can't be black, reset to any non-black color if black is entered ). Add a new constructor to pass the color attribute as an argument. Add an instance method to display all properties of a Circle object. Create 2 objects using different constructors in test file, with invalid data. Use this test java file test java file: class CircleTest{ public static void main(String[] args){ int num = 10; Circle c1 = new Circle(0.001); Circle c2 = new Circle("black", -9); c1.display(); c2.display(); c1.setRadius( -1); c1.setColor("black"); c1.display(); }}

mau Open Leathing inta... - The class has data members that can hold the name of your cube, length of one of the sides and the color of your cube. - The class has a constructor that accepts the name, length of one of the sides, and color as arguments and sets the data members to those values. - The class has the following methods to set the corresponding data member. setName(string newName) setSide(double newSide) setColor(string newColor) - The class has a method called getVolume() that returns the volume of the cube, calculated by cubing the length of the side. - The class has a method called volumelncrease(double newVolume) that receive the percent the volume should increase, and then the side to the corresponding value. i - For example, 2.5 indicates 2.5% increasing of the volume. So you take the current volume, increase it by 2.5%, and then find the cube root to calculate the new side length. You can use the built in function called cbrt, part of the math library, to find the cube…
Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…
Design a class named Rectangle to represent a rectangle. The class must have the following: • double data fields named width and height. The default values are 1 for both width and height A no-argument constructor that creates a default bag. A constructor that creates a rectangle with the specified width and height A getParameter() method to return the perimeter. • A getArear() method to return the area of the Rectangle. Create two Rectangle objects. One with width 4.0 and height 10.0. The other object has width 6.3 and height 10.5.
Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"

Create a class called GraduateStudent that has the following attributes: GraduateStudent String - FirstName String - LastName String - Major String - Minor Integer - UIN Double - GPA GraduateStudent() GraduateStudent(FirstName, LastName, Major, Minor, UIN, GPA) calculateFinalGrade(Double, Double, Double) - Double getFirstName() - String setFirstName(String) - void getLastName() - String setLastName(String) - void getMajor() - String setMajor(String) - void getMinor() - String setMinor(String) - void getUIN() - Integer setUIN(Integer) - void getGPA() - Double setGPA(Double) - void toString() - String compareTo(GraduateStudent) - Integer equals(GraduateStudent) - Boolean Note: The calculate final grade takes 3 doubles, each of which will be an exam grade out of 100. The first two exams are worth 25% of the final grade, and the third exam is worth 50% of the final grade. You should return this final grade as a double.
Create a BowlingTeam class The class has 2 fields: a field for the team name and an array that holds the team members’ names. Create get and set methods for the teamName field. Add a setMember method that sets a team member’s name. The method requires a position and a name, and it uses the position as a subscript to the members array. Add a getMember method that returns a team member’s name. The method requires a value used as a subscript that determines which member’s name to return. Create a BowlingTeamDemo class. In the main method include the following: Declare 2 variables: name and a constant NUM_TEAMS that holds 4 Bowling Team objects. Declare and instantiate an array teams of BowlingTeam objects. Using nested for loops, prompt the user to enter the 4 team names and enter the team members’ names. Using another nested for loop, output each team’s name and their team members’. Output should look like: Members of team The Lucky Strikes Carlos Diego Rose Lynn Members of team I…
Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230
