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…(1) Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructor Implement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Ex. of print_item_description() output: Bottled Water: Deer Park, 12 oz. (2) Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. Parameterized constructor which takes the customer name and date as parameters Attributes customer_name (string) - Initialized in default constructor to "none" current_date (string) - Initialized in default constructor to "January 1, 2016" cart_items (list) Methods add_item() Adds an item to cart_items list. Has parameter ItemToPurchase. Does not return anything. remove_item() Removes item from cart_items list.…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.
- The class "Plant" has the following attributes: name (String), family (String), lifeSpan (int). Write a constructor method for the "Plant" class that takes values as parameters for all these attributes. A- BI II !!Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…Modify the Car class example and add the following: A default constructor that initializes strings to “N/A” and numbers to zero. An overloaded constructor that takes in initial values to set your fields (6 parameters). accel() method: a void method that takes a double variable as a parameter and increases the speed of the car by that amount. brake() method: a void method that sets the speed to zero. To test your class, you will need to instantiate at least two different Car objects in the main method in the CarDemo class. Each of your objects should use a different constructor. For the object that uses the default constructor, you will need to invoke the mutator methods to assign values to your fields. Invoke the displayFeatures() method for both objects and display the variables. Demonstrate the use of the accessor method getColor() by accessing the color of each car and printing it to the console. Use the method accel to increase the speed of the first car by 65 mph. Use…
- The class "Student" has the following attributes: studentId (int), name (String), surname (String), deptCode (String).Write a constructor method for the "Student" class that takes values as parameters for all these attributes.Language is Java Write a Clothing class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "Doctor Who hoodie", "slacks") price (e.g., 19.99, 7) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 Clothing objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a Clothing object whose color was blue, whose display name was work trousers, for a price of 27.99, you could use the getters to print something like this:These work trousers are blue and cost $27.99.Don't hardcode the print statement for full credit, you must use the gettersCreate a class BeautyProduct with name, color, brand. Provide Constructors, getters, setters and also write toString method. Now create a class Lipstick which extends the class BeautyProduct as Lipstick is-a Beauty Product it has totalVolume, remainingVolume, price, texture (gloss, matt) as private data members. Provide Constructors, getters, setters and an apply() method whenever this method is called a beauty item is applied and its volume decreases by 10.This should also check that volume must not be zero if it then u have to throw exception. Also write toString method which prints all details like name, color, brand, price, texture and volume. Create another class foundation having totalVolume, remainingVolume, price, texture (liquid, cake) and lastingTime (number of hours foundation remain intact on face and does not crease) as private data members. This also extends the base class i.e. BeautyProduct. Provide Constructors, getters, setters and an apply() method whenever this…
- Write a shoe class with the following attributes: color (e.g., "blue", "green", "orange") displayName (e.g., "nikes, adidas", "puma") price (e.g., 100, 200,60) Include only one constructor. It should have parameters for each of the attributes and set their values. Additionally, include getters and setters for each of the attributes. Add a driver, name it Purchases, and create 2 objects. Finally, print out some information about both objects (i.e., print the information from some or all of the getters). For example, if you created a shoe object whose color was blue, whose display name was shoes , for a price of 230, you could use the getters to print something like this:These work trousers are blue and cost $230This is the question - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum. The Rock class contains the following fields: sampleNumber - of type int description - A description of the type of rock (of type String) weight - The weight of the rock in grams (of type double) Include a constructor that accepts parameters for the sample number and weight. The Rock constructor sets the description value to "Unclassified". Include get methods for each field. Create three child classes named IgneousRock, SedimentaryRock, and MetamorphicRock. The constructors for these classes require parameters for the sample number and weight. Search the Internet for a brief description of each rock type and assign it to the description field using a method named setDescription inside of the constructor. I am only missing two checks and they seem to be with the rock, here is my code then I will copy one check - import java.util.*;…This is the question - Create a class named Rock that acts as a superclass for rock samples collected and catalogued by a natural history museum.
