2.3. Third Exercise Create a Point class (or change the corrected version from Exercise 01) with two private properties representing x and y coordinates, each of which defaults to the constants originx and originY, which are both initialised to 0. Provide three overloaded constructors: the first one sets the coordinates to their default values; the second gets the coordinates x and y as parameters; and the third receives an object of type Point and transfers its coordinates to the current (this) Point object. Provide a function toString() { [native code] } function that returns a String containing the point coordinates; an example of the delivered result is as follows: (5.1.3, 2.3) Create a PointTest class to put the various constructors and function toString() { [native code] } function to the test.

1. 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.
Part (1) Define a class with the following specification: The class name is Exam with three private data members: exam course code (String), exam score (double) for the student, and maximum exam score maxScore (double). b. Write a constructor that initializes all the data members of the class from its parameters. If maxScore is less than score, then set them to zero and print a message for this change. Provide an accessor (get) method and a mutator (set) method only for the score data member. Make sure that the new score in the set method does not exceed maxScore, otherwise leave the current value of score unchanged. d. Define a method called addBonus() that adds a given bonus score, as input parameter, to the student's score. If the new score after adding the bonus exceeded the maximum score, then set score to maxScore. Define a method called percentage() that returns the exam percentage out of 100. Define a method called displayExamDetails() to display on the screen exam details as…
objective of the project: Implement a class address. An address has a house number street optional apartment number city state postal code. All member variables should be private and the member functions should be public. Implement two constructors: one with an apartment number one without an appartment number. Implement a print function that prints the address with the street on one line and the city, state, and postal code on the next line. Implement a member function comesBefore that tests whether one address comes before another when the addresses are compared by postal code. Returns false if both zipcodes are equal. Use the provided main.cpp to start with. The code creates three instances of the Address class (three objects) to test your class. Each object will utilize a different constructor. You will need to add the class definition and implementation. The comesBefore function assumes one address comes before another based on zip code alone. The test will also return…

write a class Point with parametrized constructor. This class have four member variables, a,b,c,d. Write the following member functions a. drawTriangle(int x, int y, int z ) b. drawRectangle(int x, int y, int z, int a). Each function should display the length of lines for each of the shape (triangle, rectangle). For example triangle should calculate length of its three lines by following methods as shown in code. Note: the number of lines depends on the name of shape. void drawTriangle(int x, int y, int z ) { int line 1 = x - y; // convert to positive value if line length is negative int line 2 = y -z; int line 3 = z -x; cout<< The length of each lines is: << //// here display length of each line with proper formatting. } Write similar code for drawRectangle(int x, int y, int z, int a). Wtite main function to call these three function
Consider a class "Fan" with two integer data members, "state" (0/1 i.e. on or off) and "speed". 1. Write a parameterized Constructor for this class. 2. Write a member function "changeState( )" which behaves similar to pressing a button i.e. it should change the state of the fan. If it is off (0), calling the function should turn it on (1) and vice versa.. Multi Line Text.

1) Define a Person class containing two private attributes: last name, first name. Provide this class with a constructor allowing the initialization of its attributes and a method that displays the last name and first name of a person: void display (). 2) Define a Customer class inheriting from the Person class and having a private attribute: numidentity. Provide this class with a constructor allowing you to create a customer from their last name, first name and identity card number and a method: • void display() which displays the last name, first name and ID number of a customer. 3) Define an Owner class inheriting from the Person class and having two private attributes: name of the video club (nomclub), address of the club (adrclub). Provide this class with a constructor allowing to create a landlord from his name, his first name, the name of his video club, the address of his club and a method: • void display() who displays the name, first name, last name and address of his video…

Consider the definition of the following class: (1, 2, 3, 5, 7) a. Give the line number containing the constructor that is executed in each of the following declarations. b. Write the definition of the constructor in Line 4 so that the instance variables are initialized to " ", " ", " ", 0, 0.0, and 0.0, respectively. c Write the definition of the constructor in Line 5 so that the string instance variables are initialized to"", and the other instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. d. Write the definition of the constructor in Line 6 so that the instance variables productName and manufacturer are initialized to the empty string, instance variable id is initialized according to the first parameter, and the remaining instance variables are initialized according to the last three parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. e. Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters.

Define a class named Employee. This class should extend the Person class from the previous question. The class should have a constructor, which takes the name, age, employer (String) and salary (int) as parameters (in that order). The first two parameters should be passed to the constructor of the superclass and the value of the last two parameters should be stored in instance variables. The class should define the methods, getSalary which returns the salary of the employee and getEmployer which returns the name of the employer. Any methods from the previous question that need to be overridden should be overridden! Use super and instanceof as appropriate. I.e., for the following methods you should be able to call the method in the superclass for specific situations (e.g. the compareTo method in the superclass can be called if you receive anything other than an Employee, and this also holds for the equals method). The toString method only needs to append details and as such can also…
Part (1) Create a class called HOUSE that has these private instance variables: an owner “string”, an area “double” and a pricePerMeter “double”. The class has the following methods: - A constructor that takes owner, price and area. Theconstructor sets the class variables to these values and in case the owner is empty string, set its instance variable to “unknown”. - A mutator method (set) and an accessor method (get) for the owner variable. - A method getPrice that returns the total price of the house. The total price of the house is computed by multiplying the area by the price per meter. - A method print that prints the owner, area and price per meter. Part (2)Write a Java application that asks the user to enter the owner, area and price per meter of the house. Create an object from House class you defined in Part (1) and use it to display the house information and the total price of the house.
