- 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"Design a class named CustomerRecord that holds a customer number, name, and address. Include separate methods to 'set' the value for each data field using the parameter being passed. Include separate methods to 'get' the value for each data field, i.e. "return" the field's value. Pseudocode:Challenge exercise The following object creation will result in the constructor of the Date class being called. Can you write the constructor’s header? new Date("March", 23, 1861) Try to give meaningful names to the parameters
- Define the Circle2DYourLastName class that contains: Two double data fields names x and y that specify the center of the circle withgetter methods. A double data field radius with getter method. A constructor that creates a circle with specified x, y, and radius. A method findTypeOfIntersection to determine and return types ofintersection as string (contained, overlap, or separate).Design a user class that prompts the user to enter the coordinates of the center andradius of two circles and displays the type of intersection. Allow the user to repeat yourprogram using a ConfirmDialog Box.You need 5 java classes and these include Netflix Class (Parent class of Movie and TVShow class) Movie Class TVShow Class Test/TestDriver Class Database Class Please read the questions carefully. TestDriver is given for the other image.Create a RightTriangle class given the following design: RightTriangle variables: base, height methods: 2 constructors, 1 that set default values and another that accepts to parameters. setBase - changes the base. Requires one parameter for base. setHeight - changes the height. Requires one parameter for height. getBase - returns the triangle base. getHeight - returns the triangle height. area - returns the area of the triangle (1/2bh) given the current base and height
- Create a class Course to describe a course according to the following requirements: A course has three attributes: courseName, courseCode, fees. Create a constructor without parameters to initialize all the instance variables to default values (0 for numbers and "" for a string). Create a constructor to initialize all the attributes to specific values. Add all setter and getter methods Create a tester class with the main method. The tester class must be named using your first and last In this class performs the following: Create a course object c1 using the default constructor. Create a course object c2 with the following information: courseName =” object oriented programing”, courseCode = “CS230” , fees = a value from your choice. Change the course fees of c2 to your age. Print the course information of c2 using getter methods I attached Typical run of the programDraw Design Layout References Mailings Review View Help Create a Java program and name your file: FIRSTNAME. java (for example, lohn.java). Work on the following: Create three interfaces with the names "InterfaceOne," "IrnterfaceTwo," and "Interfacelhree" In the first interface, declare a method (signature only) with a name "updateGear()." In the second interface, dedare a method (signature only) with a name "accelerate()." In the third interface, dedare a method (signature only) with a name "pusherake()." Create two classes Car and Truck that implement these three interfaces at one time. Define a new method "currentSpeed()" in both the classes to find the current speed after the brake. • Define all the three methods inside each class. The data to these methods will be provided during the object creation. Invoke the two objects with a name c1 of class Car and t1 of class Truck. • After creating the objects, call all the three methods defined above in both the classes. Pass any of the…Test your newly created subclasses inside the same TestComputer program you previouslycreated: create two new Laptops and two new Desktops with the data of your choice.

- Create a class for Subject containing the Name of the subject and score of the subject. There should be following methods: set: it will take two arguments name and score, and set the values of the attributes. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. set: it will take one double value as argument and set the value of score only. If score is less than 0 or greater than 100.0 then a message should be displayed “Incorrect score” and score should be set to Zero. display: it will display the name and score of the subject. Like “Name : Math, Score: 99.9” getScore: it will return the value of score. greaterThan: it will take subject’s object as argument, compare the calling object’s score with argument object’s score and return true if the calling object has greater score.
