- Your assignment for this course is to implement a beginner level Book Management System (BMS) in Java language. BMS contains 2 classes: Bookand BookList. The Book class has the following attributes: code: a String object, that hold the book’s code. title: a String object, that hold the book’s title. qua: int variable, that hold the number of books with the same code in the library. price: a double variable, that hold the book’s price. The BookList class contains only one data member: ArrayList<Book> t. When running the program display the menu as below:1. Input & add book(s) to the end.2. Display all books.3. Search a book for given code.4. Update the book’s price for given code.5. Find the (first) max price value.6. Sort the list ascendingly by code.7. Remove the book having given code.8. Load data from file.0. Exit.Notes:(1) The book’s code must be unique in the list.(2) Display all books in format (code, title, quantity, price).(5)…Slide Type Slide • Exercise # 1: Define a class Point that represents a point in 2 – D plane. The point has x and y coordinates. Define the following: • A constructor to initialize the x, y coordinates. • A method translate(self, dx,dy) to translate the point object dx , and dy units in x and y directions, respectively. • A method distanceTo (self, point2) to return the distance between the point referenced by self and point2. • getX(self) to return the value of x coordinate. • getY(self) to return the value of y coordinate Test the above class by: • Creating 2 point objects; one with (3,5) as x,y coordinates; the second with (-10,30) as x,y coordinates. • Move the first point 5.5 units in x direction and -12.5 units in y direction using translate method • Find the distance between the 2 points in their current location using distance To method A Sample output resulting from running the above test class is shown below new coordinates of point1= (8.5 , -7.5) Coordinates of point 2 =…Java- Suppose that Vehicle is a class and Car is a new class that extends Vehicle.

Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.
- 1. Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a color, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides, and set the color and filled properties using the input. The program should display the area, perimeter, color, and true or false to indicate whether it is filled or not.using java programmingJAVA PROGRAMMING - Create a class named "Shape" that has rhe abstract methods getArea() and getPerimeter(). - Create a class named "Rectangle", "Square", and "Circle". Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. - For rectangle, create attribute length and width. For square, side. For circle, radius Inputs: 1. Char input for Shape Type (Rectangle, Square, Circle). 2. Dimensions for specific type of Shape Output: Shape: Rectangle Length: 10 Width: 50 Area: 500.00 Perimeter 120.00Part 1: Abstract Classes 1. Copy the source files of Circle, Rectangle and GeometricObject classes (located in LabFiles folder) and paste them in the default package (You may need to fix any problems related to package declaration). 2. Open Circle, Rectangle and GeometricObject classes using NetBeans editor and go through the classes’ implementation. 3. In the GeometricObject class add two methods called respectively getArea() and getPerimeter(). Discuss: 1. Is the area formula of a circle similar to area formula of a rectangle? Since: GeometricObject is the superclass of Circle and Rectangle, and getArea() method is a common method in both Circle and Rectangle classes. Then: 2. Should you define the getArea() method in the superclass GeometricObject? Or in the subclasses Circle and Rectangle? 3. If yes, Should the getArea() method be declared as abstract method in the superclass GeometricObject? Or as instant method? 4. Is declaring getArea() as abstract, would solve…
