Please read carefully and follow the instruction:Create the following classes. Use appropriate access modifiers (instance variables should be private!) and datatypes for each. Don't forget to add getter and setter functions.1. Item: This class has the attributes (member variables) called title, description, and price.o Book: This class inherits from Item Book extends Item. It has an instance variable called pageCounto Movie: This class inherits from Item. Movie extends Item. It has an instance variable called lengtho CD: This class inherits from Item. CD extends Item. It has an instance variable called trackCount.2.Write a class called Book that contains instance data for the title, description, price, pageCount andcopyright date. Define the Book constructor to accept and initialize this data. Include setter and gettermethods for all instance data. Override toString() method to returns a nicely formatted, multi-line descriptionof the book.3.Write another class called Bookshelf, which has a name and array of Book objects. Bookshelf capacity ismaximum of five books (do not use an arrayList) . Includes method for Bookshelf that adds, removes, isFull(returns Boolean), isEmpty (returns Boolean) and toString() method that returns all information about the Booksin the Bookshelf.4. Create a driver class called Test Project, whose main method instantiates five Book objects, two Movieobjects and two CD objects. Use a constant name, no need for scanner.Example:Book b1 = new Book("Java Book","Laing",200.0,2016,"11-20-2020”);Movie x = new Movie("ET...","Et was from Jupiter”,6.0, 2);CD cd = new CD("Best","Xcompany",15.0, 120);.5.Create an array of Item of size 9.Item [] ar = new Item[9];6.

17. Phone Book ArrayList Write a class named PhoneBookEntry that has fields for a person's name and phone number. The class should have a constructor and appropriate accessor and mutator methods. Then write a program that creates at least five PhoneBookEntry objects and stores them in an ArrayList. Use a loop to display the contents of each object in the ArrayList.

1. Square Roots Create a class with a method that, given an integer, returns an array of double-precision floating point numbers (known in Java as double), each of which is a square root of a number between 2 and the parameter to the method. For example, if the parameter is 5, the method should return an array of 4 doubles, with approximate values 1.4142135623, 1.7320508075, 2.0, and 2.2360679774. Your method should check the validity of the parameter, and take appropriate action if the parameter is invalid. 2. Reading Files Create a class with a method that, given a string representing a file name, returns an integer with the number of characters in the file. For example, if the file has 10 characters, your method must return the number 10. 3. Main Class Create a class HW1.java with a main method that does both of the following: calls the method from part 1 with a random integer between 0 and 10, and prints each of the numbers in the result. The numbers should all be printed on the…

10. Lottery Application Write a Lottery class that simulates a lottery. The class should have an array of five integers named lotteryNumbers. The constructor should use the Random class (from the Java API) to generate a random number in the range of 0 through 9 for each element in the array. The class should also have a method that accepts an array of five integers that represent a per- son's lottery picks. The method is to compare the corresponding elements in the two arrays and return the number of digits that match. For example, the following shows the lotteryNumbers array and the user's array with sample numbers stored in each. There are two matching digits (elements 2 and 4). lotteryNumbers array: User's array: 7 4 4 2 1 3 7 3 In addition, the class should have a method that returns a copy of the lotteryNumbers array. Demonstrate the class in a program that asks the user to enter five numbers. The program should display the number of digits that match the randomly generated…
