Create a class named Poem that contains the following fields: title - the name of the poem (of type String) lines - the number of lines in the poem (of type int) Include a constructor that requires values for both fields. Also include get methods to retrieve field values. Create three subclasses: Couplet, Limerick, and Haiku. The constructor for each subclass requires only a title; the lines field is set using a constant value. A couplet has two lines, a limerick has five lines, and a haiku has three lines. These are the provided classes and subclasses : public class Poem { // Define the Poem class here } public class Limerick { // Define the Limerick class here } public class Haiku { // Define the Haiku class here } public class Couplet { // Define the Couplet class here } import java.util.*; public class DemoPoems { publicstaticvoidmain(String[] args) { Poem poem1 =newPoem("The Raven",84); Couplet poem2 =newCouplet("True Wit"); Limerick poem3 =newLimerick("There was an…
Jave assignment: Create a class called Player that has the following attributes: Player Health - Integer Intelligence - Integer Dexterity - Integer Strength - Integer Stamina - Integer Player() Player(Health, Intelligence, Dexterity, Strength, Stamina) getHealth() - Integer setHealth(Integer) - Void getIntelligence() - Integer setIntelligence(Integer) - Void getDexterity() - Integer setDexterity(Integer) - Void getStrength() - Integer setStrength(Integer) - Void getStamina() - Integer setStamina(Integer) - Void toString() - String compareTo(Player) - Integer equals(Player) - Boolean Notes: All attributes should not be allowed to be set below 0.
The goal of this coding exercise is to create two classes BookstoreBook and LibraryBook. Both classes have these attributes: author: Stringtiltle: Stringisbn : String- The BookstoreBook has an additional data member to store the price of the book, and whether the book is on sale or not. If a bookstore book is on sale, we need to add the reduction percentage (like 20% off...etc). For a LibraryBook, we add the call number (that tells you where the book is in the library) as a string. The call number is automatically generated by the following procedure:The call number is a string with the format xx.yyy.c, where xx is the floor number that is randomly assigned (our library has 99 floors), yyy are the first three letters of the author’s name (we assume that all names are at least three letters long), and c is the last character of the isbn.- In each of the classes, add the setters, the getters, at least three constructors (of your choosing) and override the toString method (see samplerun…
Create a new Teller Class Build a new Teller class(“Teller.java”). This class will be a sub-class of Employee. The Teller class should have all the same properties as an Employee as well as two new properties: hoursWorked and shift. HoursWorked is the total hours that this teller worked this week, and shift is either “day” or “evening” shift. Make sure to add 2 constructors and a display() method. Do not include a main() method in the Teller class. Test out this Teller class, by building a separate Tester class called TellerTester stored in a new file called ( “TellerTester.java”. This TellerTester class will only have a main() method, that will instantiate a Teller object, pass all the data to the Teller constructor, and lastly call the Teller display() method; just these 3 lines.
Create a Point class to hold x and y values for a point. Create methods show(), add() and subtract() to display the Point x and y values, and add and subtract point coordinates. Create another class Shape, which will form the basis of a set of shapes. The Shape class will contain default functions to calculate area and circumference of the shape, and provide the coordinates (Points) of a rectangle that encloses the shape (a bounding box). These will be overloaded by the derived classes; therefore, the default methods for Shape will only print a simple message to standard output. Create a display() function for Shape, which will display the name of the class and all stored information about the class (including area, circumference and bounding box). Build the hierarchy by creating the Shape classes Circle, Rectangle and Triangle. Search the Internet for the rules governing these shapes, if necessary. For these three Shape classes, create default constructors, as well as constructors…
Create a class called Elevator that can be moved between floors in an N-storey building. Elevator uses a constructor to initialize the number of floors (N) in the building when the object is instantiated. Elevator also has a default constructor that creates a five- (5) storey building. The Elevator class has a termination condition that requires the elevator to be moved to the main (i.e., first) floor when the object is cleaned up. Write a finalize() method that satisfies this termination condition and verifies the condition by printing a message to the output, Elevator ending: elevator returned to the first floor. In main(), test at least five (5) possible scenarios that can occur when Elevator is used in a building with many floors (e.g., create, move from one floor to another, etc.). Hint: Termination occurs when the instance is set to null. You may wish to investigate “garbage collection” for this exercise.
Please help me with this exercise. Thank you!
Please complete the following tasks: Write a class “Actor” that contains two attributes with the appropriate level of visibility explicitly defined. “Name” which is a String, Private, “NumberofAwards” which is an integer, private Write a default Constructor for this class that initializes the name to “Bob Smith” , and the number of awards to 0. Write an overload the constructor for this class that accepts actor’s name as a parameter Write accessor methods for each of the attributes. Write a method “winsAnOscar” that increases the number of awards by one and prints “The crowd applauds for <actor’s name>!” Be sure to use accessors where appropriate. Make sure your header is complete, with the appropriate level of visibility and any required keywords.
If you have a class named Animal, give three examples of potential objects of this class.
For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…
Part 1: Setting the turtle size when it is instantiated Currently, a turtle is created and given a default size of 50. To change the size of the turtle its increaseTurtleSizeBy10 and decreaseTurtleSizeBy10 methods can be called. Add functionality so that a turtle can be created with a specified size. In the DoodleTurtle class do the following: Overload the DoodleTurtle constructor by creating a one-parameter constructor that takes the size of the turtle as an integer. Add an empty method body. Complete the method specification for the new constructor. The default constructor method specification can be used as a model. The only difference will be that the getTurtleSize() will equal the name of the size parameter instead of INITIAL_SIZE. In the method body of the one-parameter constructor do the following in this order: Call the initializeWithDefaultValues helper method. Call the setSize method passing it the size parameter. Compile the program and fix any…
3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…
