OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

- Write code for an Invoice class for a car sale. Printing an object of the Invoice should print thedetails about the seller, the buyer, the dealer, the date of transaction, the car being sold, the purchase andselling price, the commission earned by the dealer, sales tax, and the total price of the car (calculated giventhe details in Question 3 part 3).

- Imagine a publishing company that markets both book and audiocassette versions of its works. Create a class publication that stores the title (a string) andprice (type float) of a publication. Create a default constructor and also create parameterized constructor. Also derive two other classes:book, which adds a page count(type int), and tape, which adds aplaying time in minutes (type float). Write appropriate accessor’s and mutator’s and also member functions for each class. Store all information into a file named “BookData.txt”. Read all Data from file and display it on the screen with the help of their member function. Write a main() programto test the book andtape classes by creating instances of them, asking the user to fill in data with their appropriate accessors and mutators.Identify all the classes implement inheritance between them.(Note: write data using append mode otherwise previous information will be lost).1. Create a class called Student, with the following attributes/variables:a. studentName (String)b. studentNumber (int)sc. regYear(long)d. faculty(String)e. department(String)2. Add the following methods in Student:a. accessors and mutators for all variablesb. toString methodi. Formulate your toString so that it only shows studentName,studentNumber and faculty3. Create a class called MyFriends, with the following attributes variables:a. studentArray(Student[])4. Add the following methods in MyFriends:a. fillArrayi. Using scanner ask how many students does the user want to inputii. Capture user input for all of his friends(Of course we are assuming all your friends would be similarUWC students, go ask around and meet new friends, alsopreferably not in the same Computer Science department … ifpossible … only if possible)b. maini. Call the fillArray methodii. Count how many Computer Science studentsiii. If half or more students are Computer Science students, thendisplay “You … need more…Create a Right Triangle class that has two sides. Name your class rightTraingle. Code getter and setters for the base and the height. (Remember class variables are private.) The class should include a two-argument constructor that allows the program to set the base and height. The constructor should verify that all the dimensions are greater than 0. before assigning the values to the private data members. If a side is not greater than zero, set the value to -1. The class also should include two value-returning methods. One value-returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. If either side is -1, these functions return a -1. The formula for calculating the area of a triangle is 1/2 * b*h, where b is the base and h is the height. The formula for calculating the perimeter of a triangle is b+h+sqrt (b*b+h*h). Be sure to include a default constructor that initializes the variables of the base, height to -1. To test…
- Write a program which controls a metro train and that keeps track of stations and who gets on and off. write a short description of how the code is designed. Design and implement a class called train, which has at least the following: At least the following attributes (you can include others): metroID stationNum which keeps track of the station that the train is at. iii. direction which keeps track of the direction the train is travelling in. passTotal which keeps track of the number of passengers currently on the train. A default constructor which sets the metroID to a random number between 1 and 1000, the station number to 0, the direction (int), and the passTotal to 0 (train is empty). A constructor with one parameter; the parameter is the metro id. The constructor assigns the passed integer to the metroID attribute; the rest of the attributes are set as described in the default constructor. Accessor methods for each attributes. Mutator methods for each attributes.…Question 14 papa.Write a Java class “ShoppingCart” and a Java tester class “ShoppingCartTestDrive” to implement the OOP class design: “ShoppingCart”. - Apply “Encapsulation” concept in your classes- Implement three methods addToCart(), removeFromCart(),checkOut() and print demo results to the screen Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this lineB - RobotFriend Create a RobotFriend class. RobotFriend is a new toy just on the market. Copy the starter class and the tester from Codecheck. A RobotFriend has a name and replies to various commands Provide a constructor that takes the name of the RobotFriend as a parameter. Remember that a constructor has the same name as the class. What does the class need to remember? That is the instance variable. Provide the following methods: public String getName () gets the name of this RobotFriend • public void setName (String newName) sets a new name for this RobotFriend • public String whatDoYouNeed () returns a string consisting of name + needs a battery charge" where name is the name of this RobotFriend (which was supplied in the constructor) public String doCommand (String whatToDo) returns a string consisting of "Your friend " + name + does not + whatToDo where name is the name of this RobotFriend and whatToDo is the parameter

And appropriate constructors to initialize the instance variables. Also, add member functions, to do the following: 1. Dtermine the amount of water needed to fill an empty pool or partially filled pool. 2.
