- 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.

- 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:An artist's discography includes several albums. Each album includes several songs. We want to model the Discography, Album and Song classes as follows • a discography has a single artist attribute and a total_time method that returns the total minutes corresponding to the artist's entire discography • an album has a single name attribute and a total_time method that returns the total minutes for the songs on the album a song has two attributes: title and duration and a duration method that returns the duration in minutes of the song • we want to take advantage of the composite pattern so that the duration method delivers the total number of minutes of a song, album or the entire discography of the artist depending on the object in question a) Draw a UML class diagram showing the solution b) Write the Ruby code that implements itLaboratory Exercises – Java Lesson 5: Creating Classes and Objects 2. Write a program that displays the employees Ids together with their first and last names. Use two classes. The first class contains the employee data and separate methods to set and get the ID’s and names. The other class creates objects for the employees and uses the objects to call the methods. Create several employees and display their data 3. a. Create a class named Circle with fields named radius, area and diameter. Include methods names setRadius(), getRadius(), computeDiameter() which computes a circles’s diameter and computeArea which computes a circle’s area. The diameter of a circle is twice its radius and the area is 3.14 multiplied by the square of the radius. b. Create a class named TestCircle whose main() declares three Circle objects. Using the setRadius() method, assign one circle a small radius value. Assign another circle a larger radius value and assign the third circle a radius of 1. Call…
- Create a class named Person that holds the following fields: two String objects for the person’s first and last name and a LocalDate object for the person’s birthdate. 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 named Purchase. Each Purchase contains an invoice number (private int), amount of sale (private double), and amount of sales tax (private double). Include set methods for the invoice number and sale amount. Within the set() method for the sale amount, calculate the sales tax as 5% of the sale amount. Also include a display method that displays a purchase’s details (i.e invoice, sale amount and tax). Save the file as Purchase.java. 2. Create an application (with main ()) that declares a Purchase object (using class defined in previous question) and prompts the user if he/she wants to enter an invoice number (1-yes, 0 – no). If user enters 1 then the program will prompt for an invoice number, do not let the user proceed until a number between 1,000 and 8,000 has been entered. Next, the program prompts for a sale amount, do not proceed until the user has entered a nonnegative value. Using the values entered by the user create a Purchase object, display the object’s…Design a Book class that holds the title, author’s name, and price of the book. Books’s constructor should initialize all of these data members except the price which is set to 500/-. Create a display method that displays all fields. All Books are priced at 500/- unless they are PopularBooks. The PopularBooks subclass replaces the Bookprice and sets each Book’s price to 50,000/- through PopularBooks construcor. Override the display method to display all fields. Write a Main () method that declares an array of five Book objects. Ask the user to enter the title and author for each of the 5 Books. Consider the Book to be a PopularBook if the author is one of the following: Khaled Hosseini, Oscar Wilde, or Rembrandt. Display the five Books’ details.
