- UOWD Library is asking you to write a Java program that manages all the items in the Library. The library has books, journals, and media (DVD for example). All items have a name, author(s), and year of publication. A journal also has a volume number, while a media has a type (audio/video/interactive). The user of your program should be able to add an item, delete an item, change information of an item, list all items in a specific category (book, journal, or media), and print all items (from all categories). A menu asks the user which operation s/he wants to perform. Important: make use of collections, inheritance, interfaces, and exception handling wherever appropriate.In java language Write a Rectangle class. A Rectangle has properties of width and length. You construct a Rectangle object by providing the width and length in that order. If no width and length are provided to the constructor, construct a Rectangle with width 0.0 and length 0.0. We want to be able to get and set both the width and the length independently. We also want to be able to ask for the area of the rectangle and the perimeter of the rectangle. What will the object need to remember? width and length - those are the instance variables. Rectangle class has these constructors : public Rectangle() - Constructs a new rectangle with width and length of 0.0. public Rectangle(double width, double length) - Constructs a new rectangle with the given width and length. Remember that the job of the constructor is to initialize the instance variables. It has these methods. public double getWidth() - Gets the width of this Rectangle public double getLength() - Gets the length of this…In java language Write a Rectangle class.

- FOR JAVA Write a Java class named Book, which has a name, an author and a pub- lisher. This class must also have a static field (an array with length 100) which holds names of all constructed books, and a static method which returns the number of constructed books.Write a program namedAveragesthat includes a method that accepts any number ofnumeric parameters, displays them, and displays their average. Demonstrate that theprogram works correctly when passed one, two, or three numbers, or an array ofnumbers.Create a Java class called Student with attributes name, age, and grade. Implement a parameterized constructor to initialize these attributes. Then, create an array of Student objects, populate it, and print the details of all students.
- In Java, give an example of a method that requests Name input. Then show another method, in the same application, that searches an object array in an object class for duplicates and reports an error when there is one. How would you utilize the second method with the first one?Implement the below pseudo-code in a Java program using a while loop and aswitch-case statement. The program should be well structured, and the taskperformed under each option (at least options 'b' to 'e') should be implementedas a separate method.NOTE: The Scanner class does not have a method to input a character. Inorder to read a character from the keyboard, use one of the following methods(after declaring the Scanner object):static Scanner kb = new Scanner(System.in);1. char ch = kb.nextLine().charAt(0); OR2. char ch = kb.nextLine().toLowerCase().charAt(0);where kb is a Scanner class object.The second method above also converts the input to lowercase, which is oftenuseful. Though these methods allow the user to input more than one characteron the input line, the rest of the line (after capturing the first character withcharAt(0)) is discarded.If you also want to ignore the leading spaces before the first character thenuse:1. char ch = kb.nextLine().trim().charAt(0); OR2. char ch =…FOR JAVA Write a Java class named Book, which has a name, an author and a pub- lisher. This class must also have a static field (an array with length 100) which holds names of all constructed books, and a static method which returns the number of constructed books. You must also implement its constructors (one constructor with parame- ters, one default constructor), toString method, getters and setters.
- Using the card.java class file, write a program to simulate a Deck of Cards. See Programming Project 8.7 (PP 8.7) from page 403 on textbook for a description of what your program needs to do. Note that although the book description of the problem states that you should write the Card class, I do not want you to do that. You must use the Card file exactly as it is provided (NO modifications) and only write the DeckOfCards and Driver classes. public class Card{public final static int ACE = 1;public final static int TWO = 2;public final static int THREE = 3;public final static int FOUR = 4;public final static int FIVE = 5;public final static int SIX = 6;public final static int SEVEN = 7;public final static int EIGHT = 8;public final static int NINE = 9;public final static int TEN = 10;public final static int JACK = 11;public final static int QUEEN = 12;public final static int KING = 13; public final static int CLUBS = 1;public final static int DIAMONDS = 2;public final static int…Please help me fix this java code which is supposed to be a Pac-Man game Java program is below import java.awt.*; import javax.swing.JFrame.*; public class ManyPacMans extends JFrame { public void paint(Graphics g) { g.drawghostShape(60,30,40); setBackground(Color.BLUE); g.fillghostShape(130, 30,100, 80); g.drawghostShape(60,30,40); setBackground(Color.PINK); g.fillghostShape(130, 30,100, 80); g.drawghostShape(60,30,40); setBackground(Color.RED); g.fillghostShape(130, 30,100, 80); g.drawOvalpacman(30,130,50, 60); setForeground(Color.yellow); g.fillOval(130,130,50, 60); } public Ghost(String imgPath, int x, int y, int speed, boolean ip) { super(imgPath, new int[] {0,0}, GHOST_WIDTH, GHOST_HEIGHT, GHOST_FRAMERATE, x, y); super.addFramesForAnimation("scatter", "ghost_scatter.png", 0, 0, 22,0); super.speed = speed; startX = x; startY = y; scoreValue = 200; } public ManyPacMans() { initUI(); } private void initUI() { add(new…Write a java programImagine a publishing company that markets both book and audiocassette versions of its work. Create a class publication that stores the title (a string) and price(type float) of a publication. From this class derive 2 classes: book, which adds a page count (type int); and tape, which adds a playing time in minutes (type float). Each of theses 3 classes should have a getdata() method to get its data from the user at the keyboard, and a putdata() function to display its data. Suppose you want to add the date of publication for both books and tapes. From the publication class, derive a new class called publication2 that includes this data member. Then change book and tape so ther are derived from publication2 instead of publication. Make all the necessary changes in member functions so the user can input and output dates along with the other data. For the dates, you can use the bulit-in date function which stores a date as 3 ints, for months, day and year. Write a…
