a. After the introduction of classes, in a java class, Adongo a student of the class came out with the code below. Salamatu, a student of the class said adongo’s code was full of mistakes. Explain why salamatu made that statement class Abelewas {void bankudade();int fabewoso();double AttaaAyi(int x);}class pepper extends Abelewas{public static void main(String potatoes[]) {peper ending = new bankudade();}} b. Correct the code in “a” without introducing a new class and create an instantiation of the pepper class with an object variable called bankueba. Using bankueba, initialize the methods in the Abelewas class. c. Oforiwaa a student of the java class also produced the code below in a class discussion. Salamatu, again said that Oforiwaa’s code was incomplete and was seconded by Joshua another student of the class.Correct the code without changing the access type of the variables salary, name and pension. Using the object variable shito, initialize the variables salary, name and pension…

Language: Python First, define a Product class that includes all the information about a single product. a. You will need a constructor to initialize new instances. Objects of this class should have three instance variables: name, price, and quantity in-stock. b. Add a method to your class that takes an integer count and determines whether that many of the product are in stock. c. Add another method that takes a count and returns the total cost of that many of the product. d. Finally, add a method that takes a count and removes that many of the product from the stock. Next, replace the three product lists with a single list of Product instances. Modify the rest of the code to correctly use the attributes and methods of the Products in the list. product_names = ["Ultrasonic range finder", "Servo motor", "Servo controller", "Microcontroller Board", "Laser range finder", "Lithium polymer battery"                 ]product_prices = [2.50, 14.99, 44.95, 34.95, 149.99,…

Using Python Language

1. Implement the following using JAVA :- a. Design a class named Person and its two subclasses named Student and Employee. b. Make Faculty and Staff subclasses of Employee. Please note that, A person has a name, address, phone number, and email address. A student has a class status (freshman,sophomore, junior, or senior). You can define the status as a constant. An employee has office & salary. • A faculty member has office hours and a rank. • A staff member has a title. c. Draw a UML diagram of the system.

Start with this class declaration: class Student {   int sId;   String name;   double gpa;} Implement a Comparable and Comparator interface to provide the following three (3) alternative ways of ordering for the Student objects - based on sId (i.e., assume that this is selected as the natural ordering)- based on name, - based on gpa. Next declare a list of five Student objects, initialize them with random values. Test your code by printing out each of the following on separate lines: (original list of students, sorted list of students in ascending sId order, sorted list of students in ascending name order, sorted list of students in ascending gpa order).

Use as many advanced python techniques as you can  • Write classes to support the Decrypt and the Rotation algorithms.• Use Bitsets, Bytes, where bit manipulations are needed.• Use Regular Expressions to parse and search strings.• Write any supporting classes necessary to support the Decrypt and Rotation Algorithms.• For example, the Decrypt Algorithm needs support for reading an encrypted file.• The Decrypt class is only responsible for decrypting a character, NOT reading a file ANDdecrypting each character.

Using JAVA write a code to: Implement a class Person with a name and a year of birth. Add a class Student that inherits from Person and has a major. Add a class Instructor that inherits from Person and has a salary. For each class, write the needed constructors, getters, setters, and a toString method that stringifies the instance variables in a readable format. Supply a test program that instantiates an instance of each class and exercises each method defined for the class.

Mixed Fraction Arithmetic Java Project: Problem Description: Make a java program that facilitates addition, subtraction, multiplication, and division of mixed numbers (similar with the first activity) but this time all of the inputs /outputs may involve fractions, mixed fractions, or a combination.   Points to consider:   MixedFraction class must override the operations (add, subtract, multiplyBy, divideBy) inherited from Fraction class to have a different implementation if the MixedFraction object will have a Fraction object as parameter in performing the required operation, On top of that, the inherited operations must also be overloaded to allow a MixedFraction object to accept other parameters such as a whole number or another MixedFraction object. The toString method which is inherited must also be overridden by MixedFraction to have a more appropriate return value. Further formatting must also be considered such that if the result of the operation has a zero value for the whole…

Download the file Insect.cpp(mentioned below) and use this as your start file. Inside the file you will see the implementation of the class Insect. Do the following: a. Write a class BumbleBee that inherits from Insect. Add the public member function void sting() const . This function simply prints "sting!" and a newline. b. Write a class GrassHopper that inherits from Insect. Add the public member function void hop() const . This function simply prints "hop!" and a newline. When you are done your program output should look exactly like the output provided at the end of the file. insect.cpp   #include <iostream>using namespace std; // Insect class declarationclass Insect{   protected:       int antennae;       int legs;       int eyes;         public:             // default constructor       Insect();                   // getters       int getAntennae() const;       int getLegs() const;       int getEyes() const;      }; // BumbleBee class declaration // GrassHopper class…

use java (ArrayList, inheritance, polymorphism, File I/O and basic Java) Student class: First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i)  two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii)  only necessary set and get methods for a valid class design. (iii)  a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv)  an equals method which compares two student objects and returns true if they…

Write c# equivalent statements for the following: There is a book library. Define classes respectively for a library. The library must contain a name and a list of books (use array). The books only contain author name as information. In the class, which describes the library, create methods to add a book to the library, to search for a book by a predefined author, and to delete a book from the library. Write a test class, which creates an object of type library, adds several books to it. Implement a test functionality, which finds all books authored by Stephen King and deletes them. Finally, display information for each of the remaining books.

* See attatched photo Suppose we have the following class: class C { /* ... */ public: int foo (); int bar (); }; Also suppose that this class is only available in compiled form, i.e., that it cannot be modified. Now we want to add an alternative implentation that only has a method foo() but that does not have a method bar() and does not inherit the data members from class C. I.e., this new class D would have the structure class D /* ... */ { public: int foo (); }; but it cannot inherit from class C. Suppose we want to maintain a list of objects that can be from either classes C or D. Explain how you can design this list data structure, traverse the list, and call foo() on each element, such that the appropriate method C::foo() or D::foo() is executed depending on the type of the object. Do not use either if-statements or structural subtyping. Hint: There are at least three possible solutions; each one requires you to define two or more classes in addition to the list class.

please solve in python languange and use proper comments for better understanding . Thank you.

Explain how to limit the occurrences of coupling in the following systems. a) The public class variables minClassSize and maxClassSize exist in the CourseSection class. The university management changes this from time to time. These variables are accessed by several methods in the Student and Registration classes. b) A user interface class imports a huge number of Java classes, including drawing images, creating Ul controls, and a variety of additional utility classes. b) A class named Address exists in a system. This class includes four public variables that represent various aspects of an address. Several distinct classes, such as Person and Airport, control instances of this class by changing the address properties directly. In addition, several methods specify an Address as one of their parameters.
