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)

Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. Ex. For the following students: Henry Bendel 3.6 Johnny Min 2.9 the output is: Course size: 2 public class LabProgram {    public static void main (String [] args) {       Course course = new Course();            // Example students for testing      course.addStudent(new Student("Henry", "Bendel", 3.6));         course.addStudent(new Student("Johnny", "Min", 2.9));              System.out.println("Course size: " + course.courseSize());    } }   public class Student {     private String first;  // first name    private String last;   // last name    private…

I'm learning java in college and I missed one homework assignment. Since then it has been difficult to keep up with homework because they were based on the one I missed. Here's the prompt: Design a class Phone with one data member as long phoneNumber. Add constructors, get/set methods to class Phone. Then design a class InternationalPhone as subclass of class Phone, with one extra data member as int countryCode. Add constructors, get/set methods to class InternationalPhone. Write a main program to test these two classes. (We use netbeans btw) I can't get any credit for this so there's no rush but I would be very happy to recieve an answer before the end of the semester. Thank you in advance :)

Written in Python  It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods
