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:
Create a Student class, include
2 properties: name - String, age - int;
2 constructors: Student(), and Student (String str, int num);
3 methods: setName(String name), getName(), greeting();

- The class "Car" has the following attributes: plate (String), mark (String), model (String), year (int), km (int).Write a constructor method for the "Car" class that takes values as parameters for all these attributes.Cake For this, we are editing the cake class You need to make 2 private properties with these names and datatypes: name (String), price (int) You need to make a constructor with no parameters and set the name to "Velvet" and price to 6 Both variables need set/get methods (setName, getName, setPrice, getPrice) Create a print method that prints the 2 properties. So, if the name was "Vanilla" and the price was 11, this would print:Vanilla 11 Main Skeleton public class Main { public static void main(String[] args) { Cake c = new Cake(); System.out.println(p.getName()); System.out.println(p.getPrice()); p.setName("Vanilla"); p.setPrice(11); p.print(); }}Given the following class: public class Student { private long ID; private String name; } Write two constructor methods for the Student class, one without parameters and the other with.
- 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…Write the complete equals method (including the method header) for the Appliance class. Two appliance objects are logically equivalent if they have the same description (ignoring capitalization), id (ignoring capitalization), and price. As an example, the two appliances with this data would be considered equal: "dishwasher", "ABC123", 999"DISHWASHER", "abc123", 999 Here is the appliance class: public class Appliance { private String description; private String id; private int price; // using an int for simplicity public Appliance(String description, String id, int price) { this.description = description; this.id = id; this.price = price; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } public String getId() { return id; } public void setId(String id) { this.id = id; } public int getPrice() {…Create a class Animal Create a class Cat, and a class Dog, and a class Bearded Dragon which extend Animal. Add to your Animal class: Member: name Methods: Public Animal (String name) //constructor public void makes Sound () with the implementation printing out a generic animal sound. Next, override (add) the makes Sound() method to your Cat and Dog class, with the implementation specific to each animal (i.e, cat says purr..). Do not override the makesSound() for your Dragon (bearded dragons don't make sounds!) Note, you'll also need a constructor in each of your subclasses which calls super(name) to initialize the common 'name' member of Animal. Next (in your test harness) create a List of different Animals ( a couple cats, a dog, a dragon... ) and add these Animals to your list. Iterate through your list & call makeSound on each. (you should observe the makeSound method called will be: cat -> from Cat class, dog-> from Dog class, bearded Dragon -> from Animal class ) EC:…
