Create a subclass of the Course class named OOPCourse3. Create a constructor that initialises the following attributes and assigns these values: --- "description" with a value "OOP Fundamentals" --- "trainer" with a value "Mr Anon A. Mouse"4. Create a method in the subclass named "trainer_details" that prints what the course is about and the name of the trainer by using the description and trainer attributes.5. Create a method in the subclass named "show_course_id" that prints the ID number of the course: #123456. Create an object of the subclass called course_1 and call the following methods contact_details trainer_details show_course_id These methods should all print out the correct information to the terminal On a side note, this task covers single inheritance. multiple inheritance is also…solve this question using java also you will need do use a file in driver class ,d1 will help you to understand the realation between the classes, and d3 to know the function in index A you must define a class named MediaRental that implements the MediaRentalInt interface functionality(index A). You must define classes that support the functionality specified by the interface:. Define a class named MediaRental. Feel free to add any instance variables you understand are needed or any private methods. Do not add any public methods (beyond the ones specified in the MediaRentalInt interface).. The media rental system keeps track of customers and media (movies ,music albums and games). A customerhas a name, address as string , a plan and two lists. One list represent the media the customer is interested inreceiving and the second one represents the media already received (rented) by the customer. There are twoplans a customer can have: UNLIMITED and LIMITED. UNLIMITED allows a customer to…Create a class Client_Information, inherited from the class personType with an additional data member to store Emirates ID, Age, date of birth.

- IN JAVA Write a class Store which includes the attributes: store name, city. Write another class encapsulating an Art Gallery, which inherits from Store. An Art Gallery has the following additional attributes: how many paintings are sold every year and the number of artists submitting artwork. Code the constructor, accessors, mutators, toString and equals method of the super class Store. Code the constructor, accessors and mutators for the subclass Art Gallery. In the Art Gallery class, also code a method returning the average number of paintings per artist. You should create a test class which creates 2 Art Gallery objects, then calls your set methods, get methods, toString and equals methods and average paintings per artist for the Art Gallery objects.Exercise: Exercises Write a class named Octagon that extends GeometricObject and implements the Comparable and Cloneable interfaces. Assume all eight sides of the octagon are of equal length. The area can be computed using the following formula: The Octagon class has a private double data field named side with its getter and setter methods. The class has a no-arg constructor that creates an Octagon with side 0, and a constructor to create an Octagon with a specified side. Write a test program that creates an Octagon object with side value 5 and displays its area and perimeter. Create a new object using the clone method, and compare the two objects using the compareTo method. As far as classes go, the abstract GeometricObject class contains the abstract doubles getArea() and getPerimeter(). The programming language used in this exercise is Java, and it covers the Interfaces topic. I did get how most of the program should look like, but I'm facing trouble understanding a few…Design a new Account class as follows:■■ Add a new data field name of the String type to store the name of thecustomer.■■ Add a new constructor that constructs an account with the specified name, id,and balance.■■ Add a new data field named transactions whose type is ArrayList thatstores the transaction for the accounts. Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account. Print an account summarythat shows the account holder name, interest rate, balance, and all transactions.
- Q1: Write a class named as Bus that contains the attributes which are mentioned below: The name of Bus. The direction of Bus (North (N), South(S), East(E), West (W)) The position of Bus (from imaginary zero point)The class has the following member functions: A constructor to initialize the attributes Turn function to change the direction of bus to one step right side (e.g if the direction isto East, it should be changed to South and so on) Overload the Turn function to change the direction to any side directly. It should take thedirection as an argument. Move function to change the position of the Bus away from imaginary zero point. Itshould accept the distance as an argument.Java Programming Using seriazation in java Create a class named CellPhone implementing that has 4 data members - load, talkTime (min), ratePerMinute, ratePerText . Define 3 constructors - one is the default constructor , second a constructor that would initialize all the attributes , and third is a constructor that allows the user to initialize all the attributes except the load, instead, directly set load to 300. Also, define getter and setter methods for all attributes.Implement these methods : (1) callCost that would return the total cost of the call based on the parameter 'duration' (2) canCall method that returns true if parameter 'duration' (in min) is less than or equal to the available 'talkTime' and you have enough load to complete the call. [HINT: call callCost method and deduct the talkTime] (3) isLowBat method that returns true if the talkTime is equal to zero (4) canText method that reduces the load by its ratePerText and returns true if text is successfully…Create an abstract NewspaperSubscription class with fields for the subscriber name, address, and rate. Include get and set methods for the name field and get methods for the address and subscription rate; the setAddress() method is abstract. Create two subclasses named PhysicalNewspaperSubscription and OnlineNewspaperSubscription. The parameter for the setAddress() method of the PhysicalNewspaperSubscription class must contain at least one digit; otherwise, an error message is displayed and the subscription rate is set to 0. If the address is valid, the subscription rate is assigned $15. The parameter for the setAddress() method of the OnlineNewspaperSubscription class must contain an at sign (@) or an error message is displayed. If the address is valid, the subscription rate is assigned $9. Finally, write an application that declares several objects of both subscription subtypes and displays their data fields

Add: Prompts user for book data and add to the inventory list. If the book alreadyexists (based on id value), the add request will fail and an error message will beprinted to the consoleb. Remove. Prompts user for book id, finds the id in the inventory list and removesit. If the book matching the id is not in the inventory, remove request will fail andan error message will be printed to the consolec.
