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:
i know that
class A: def __init__(self): self.x = 0
class B(A): def __init__(self): super().__init__() self.y = 1
calls super() function , but what does A in super(A) means?
class B(A): def __init__(self): super(A).__init__() self.y = 1
Step by step
Solved in 2 steps
- 1 - Student class Make a class student (in student.py) that stores the following information for a student: Name (name) Student number (student_nr) Points per assignment (points_per_assignment) Exam grade (exam_grade) a) Behind each point of information is the name of the parameter to the initializer method. Store this information from the parameters in the object attributes with the same name. b) Add a method course_points() which returns the number of course points the student has gotten. Example: mary = Student("Mary", 15789613, [10, 9, 8, 10, 9, 10], 9)print(mary.course_points()) > 121 The calculation of the course points is explained in the course overview, course setup slides (Links to an external site.) and the first lectureLinks to an external site.. c) Add a method grade() which returns a the final grade of the student, rounded to nearest half (upwards, 6.75 -> 7). As per regulations, a 5.5 becomes a 6. If the student did not pass both the assignments (>= 95…All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.The total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four products (two necessary and two luxury) and store them in the product array, print out each item in the array, and display the total cost of the items. You should not make any changes at all to Product.java, and you should only add to ShoppingTripStartingCode.java. Do not change any code that is already present Example(Cheese and bread are necessities and soda and candy are luxuries)Cheese…
- A complex number has the form a+bi ,can be expressed as the ordered pair of real numbers (a,b).Theclassrepresents the real and imaginary parts as double precision values.Provide a constructor that enables an object of this class to be initialized when it is instantiated. The constructorshould contain default values.Provide Public member functions for each of the following arithmetic’sfunctions (addition –subtraction –multiplication –division), a complex absolute value operation, printing the number in the form (a,b), printing the real part , printing the imaginary part and final overload the == operator to allow comparisons of two complex numbers.Include any additional operations that you think would be useful for a complex number class.Design, implement, and test your class.write a java program for Driving license test..The local SAAQ (Société de l’Aassurance automobile du Québec) has asked you to write a program that grades the written portion of the driver’s license test. The exam booklet has 5 multiple choice questions. Here are the correct answers (answer key) for questions numbered:1. B 2. D 3. A 4. A 5. CWrite a class named DriverExam whose objects, each of which maintains the data of a candidate, and the following are the private fields (field name in bold font):• a static constant integer field (totalQs) initialized to value 5 for total number of questions. It shouldbe used instead of hard coding because SAAQ can easily increase questions in future.• a static constant array of characters (answer) initialized to correct answer key given above.• a static integer field (candidates) initialized to value 0 for the number of candidates taking examwhich should be incremented upon creating an object of DriverExam for a candidate.• a string field (name) to…Modify the above code to use the alternative method for multithreading (i.e., implementing the Runnable interface). Name your main class RunnableHelloBye and your subsidiary classes Hello and Goodbye respectively. The fi rst should display the message ‘Hello!’ ten times (with a random delay of 0–2 s between consecutive displays), while the second should do the same with the message ‘Goodbye!’. Note that it will NOT be the main class that implements the Runnable interface, but each of the two subsidiary classes.
- suppose there is a class Roster. Roster has one variable, roster, which is a list of tuples containing the names of students and their numerical grades- for example, [('Richard',90), ('Belle',67), ('Christine',85), ('Francine',97)]. Roster has a function called calculateAverage that calculates the average of the students in their roster. Write a statement that returns the average of the Roster object englishClass, which has already been defined. using pythonGiven the provided class, please make the following modifications. class Employee: def __init__(self, name, number): self.name = name self.number = number class ProductionWorker(Employee): def __init__(self, name, number, shift_number, employee_number): Employee.__init__(self, name, number) self.shift_number = shift_number self.employee_number = employee_number # Create an instance of the ProductionWorker class and test itemployee1 = ProductionWorker("John Doe", 1234, 2, 5678)print(employee1.name)print(employee1.number)print(employee1.shift_number)print(employee1.employee_number) Write a class that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object's data attributes.
