Declare and implement 5 classes: FloatArray, SortedArray, FrontArray, PositiveArray & NegativeArray. 1- The FloatArray class stores a dynamic array of floats and its size. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the end of the array.- Overloading for the insertion operator << to write the array to afile (ofstream)- Overloading for the extraction operator >> to read the array elements from the file (ifstream) and add them to the array.- A destructor to deallocate the array2- The SortedArray inherits from FloatArray. It has:- A parameterized constructor that takes the array size. - An add method that adds a float at the right place in the arraysuch that the array remains sorted with every add. Don’t add to the array then sort but rather add in the right place.3- The FrontArray inherits from FloatArray.

P8.2 Implement a class Quiz that implements the Measurable interface. A quiz has a score and a letter grade (such as B+). Use the Data class of Exercise P8.1 to process an array of quizzes. Display the average score and the quiz with the highest score (both letter grade and score).
1- Why are the methods getlndexOf and removeEntry in the class ArrayBag private instead of public? 2- Implement a method replace for the ADT bag that replaces and returns a specified object currently in a bag with a given object. 3- Suppose that a bag contains Comparable objects such as strings. A Comparable object belongs to a class that implements the standard interface Comparable, and so has the method compareTo. Implement the following methods for the class ArrayBag: The method getMin that returns the smallest object in a bag The method getMax that returns the largest object in a bag The method removeMin that removes and returns the smallest object in a bag The method removeMax that removes and returns the largest object in a bag

Use NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables. For example, the payrate should not be negative. Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using). Finally, the…
1. Implement the above system using inheritance in the best possible way. Keep every object size as small as possible. Implement all methods (setter/getter/constructors and destructors) Note that the region area is 0 while the city is len*width and the country is the sum of their cities. 2. Create array of countries called Arab of 22 countries, Write a function fill that fills the arrav Arab 3. Write a method that finds the city that has the max area in a country 4. Write a method that sorts the cities in a country from the largest to the smallest area 5. Write a function that retums array of countries of the same area of Arab 6. Write a function that compares between two countries. It returns true if countryl area greater than country2 area. 7. Write a function to move a city from one country to another.
Implement the following tasks by using concepts of object-oriented programming (Java). i. Create a generic class with a type parameter that simulates drawing an item at random out of a box. This class could be used for simulating a random drawing. For example, the box might contain Strings representing names written on a slip of paper, or the box might contain Integers representing a random drawing for a lottery based on numeric lottery picks. Create an add method that allows the user of the class to add an object of the specified type along with an isEmpty method that determines whether or not the box is empty. Finally, your class should have a drawItem method that randomly selects an object from the box and returns it. If the user attempts to drawn an item out of an empty box, return null. Write a main method that tests your class.ii. The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of rolling any digit from 1 to…

3.25 Fixed Sized Deque Your task is to create an implementation of the Java Deque interface that can only hold N items where N is a number passed into the constructor. Note that most (if not all) of the unit tests rely on the method object[] toArray() inherited from Collection. Therefore, you must make sure you implement that method correctly in order to get most of the points. 301664.1524810.gpazay7 LAB АCTIVITY 3.25.1: Fixed Sized Deque 0/ 70 Submission Instructions Compile command javac FixedsizedDeque.java -xlint:all -encoding utf-8 We will use this command to compile your code Upload your files below by dragging and dropping into the area or choosing a file on your hard drive.

Design and implement a Java class named Book with two data members: title and price. The class should have suitable constructors, get/set methods, and the toString method. Design and implement another Java class named BookShelf which has an ArrayList data member named bookList to store books. The class should have suitable constructors, get/set methods, and the toString method, as well as methods for people to add a book (prototype: addBook(Book book)), remove a book (prototype: removeBook(Book book)), and search for a book (prototype: findBook(Book book)). Test the two classes by creating a Bookshelf object and five Book objects. Add the books to the bookshelf. Display the contents of the bookshelf. Test the removeBook and findBook methods as well. Take screenshots of your tests and submit them with your Java code (not the whole project)
