- Instructions: Write your answer on a piece of paper with your name on top. Take a picture and submit within the allocated time limit. Problem 1: Implement class Employee as illustrated below. Apply appropriate constructors, encapsulate, and override toString and equals. Student Course Problem 2: «interface Payable abstract Employee Person SalariedEmployee Idno Name Employee Superclass Department Salary Subclass getPayment Amount() firstName, lastName, SSN weeklysalary Given the class hierarchy: 1. Define the interface Payable. 2. Define the class Employee that implements Payable and encapsulate. 3. Define SalariedEmployee and encapsulate. Implement getPayment Amount(). getPayment Amount() - returns a double amount that must be paid for an object of any class that implements the interface. For SalariedEmployee, it would just return the value returned by getWeeklySalary(). for new files: 128MBIn this question, we will bake a class. Create a class Cake , with the following instance attributes: • name (a string) • ingreds (a list of strings) • price (a float) The Cake class has also the following methods: • Write a constructor that takes as input a string indicating the cake name, and a list of strings indicating the cake ingredients. (No docstring needed.) The constructor uses these values to initialize the attributes accordingly. Note that each cake should be assigned a random price between $10.00 (inclusive) and $15.00 (exclusive). You may import random . Moreover, a cake must contain at least three or more ingredients. If this is not the case, the constructor should raise a ValueError . For this constructor, do not worry about making a copy of the input array. You can simply copy the reference received as input into the corresponding attribute. 1 • Write a method (including docstring) called __str__ which returns a string containing the name of the cake and its price…Java - Polymorphism Create a class named “Shape” that has the abstract methods getArea() and getPerimeter(). Create classes named “Rectangle”, “Square”, and “Circle”. Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. For rectangle, create attribute length and width. For square, side. For circle, radius. Inputs 1. Char input for Shape type (R/S/C) 2. Dimensions of specific type of Shape C 5 Sample Output Shape(R/S/C): R Length: 10 Width: 50 Area: 500.00 Perimeter: 120.00
- 3. Design a user-defined class called Course. Each course object will hold data about a course. The data includes courseID, courseName, credits and instructorName. Define the instance variables required of the appropriate type. Provide only get methods along with toString() and equals() methods. Design another user-defined class called Student. Each student object will hold data on name, GPA and courseList. Make sure to define courseList as an ArrayList holding references to Course objects Implement a constructor that will take values to initialize name, and gpa while courseList is initialized to an ArrayList() object. Provide the following get methods: getStudent ID ( ), getName(), getGPA (), get Gender(), and get CourseList() Note: the getCouresList() method will return a copy of the coureList arraylist with copies of course objects. Provide the following set methods: setName(), setGPA (), setGender() Another method: addCourse () that will take a Course object and add it to the…Books can come in various formats, like paper books, audio books, ebooks, etc. Create a generic classBook that has as common attributes the title, the year of publication, and the author. The constructor of thisclass should instantiate all three attributes. Override the toString method of class Book that returns a stringthat contains the values of its attributes. Create a subclass PrintBook that extends Book with attributesPublisher and ISBN. Create another subclass AudioBook which has the book’s size (in MB), its playlength and the playback artist’s name as attributes. Both PrintBook and AudioBook classes override thetoString method inherited from Book. Write a Java application to demonstrate the usage of this hierarchy.Code: import java.util.*; //Bicycle interface interface Bicycle { abstract void changeCadence(int newValue); //will change value of candence to new value abstract void changeGear (int newValue); //changes gear of car abstract void speedUp(int increment); //increments speed of car by adding new Value to existing speed abstract void applyBrakes(int decrement); } //ACMEBicycle class definition class ACMEBicycle implements Bicycle { int cadence = 0; Â Â int speed = 0; Â Â int gear = 1; //methods of interface public void changeCadence(int newValue) { this.cadence=newValue; } public void changeGear (int newValue) { this.gear=newValue; } public void speedUp(int increment) { this.speed+=increment; } public void applyBrakes(int decrement) { this.speed-=decrement; } //display method void display() { System.out.println("Cadence: "+this.cadence); System.out.println("Gear: "+this.gear); System.out.println("Speed: "+this.speed); } } //KEYOBicycle class definition class KEYOBicycle implements…
- This is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable ClassWrite a class definition line and a one line docstring for the class Dog. Write an __init__ method for the class Dog that gives each dog its own name and breed. Test this on a successful creation of a Dog object.>>> import dog>>> sugar = dog.Dog('Sugar', 'border collie')>>> sugar.name'Sugar'>>> sugar.breed'border collie' Add a data attribute tricks of type list to each Dog instance and initialize it in __init__ to the empty list. The user does not have to supply a list of tricks when constructing a Dog instance. Make sure that you test this successfully.>>> sugar.tricks[] Write a method teach as part of the class Dog. The method teach should add a passed string parameter to tricks and print a message that the dog knows the trick.>>> sugar.teach('frisbee')Sugar knows frisbeeImplement the following parking permit class using java It has a dependency on the car class, no need to implement the car class.
