Your task is to create two classes namely data and calculation. The calculation class is a friend of the data class. The data class will be composed of two floating point data members namely a and b. The class will also be composed of a friend function display that can display all the data members.

JAVA Language Caesar Shift Question: Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.) import java.util.*; public class TestCipher { public static void main(String[] args) { int shift = 7; Caesar caesar = new Caesar(); String text = "hello world"; String encryptTxt = caesar.encrypt(text); System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt); } } abstract class Cipher { public String encrypt(String s) { StringBuffer result = new StringBuffer(""); // Use a StringBuffer StringTokenizer words = new StringTokenizer(s); // Break s into its words while (words.hasMoreTokens()) { // For each word in s…

#pyhton programing topic: Introduction to Method and Designing class Method overloading & Constructor overloading ------------------ Question 1 Suppose your little sibling wants your help to check his math homework. He is done with his homework but wants you to see if all his results are correct. Since the student with all correct results gets 3 stars. However, you want your brother to check this on his own. So, you design a calculator for him in python. You could have given your scientific calculator but you wanted to give him a basic calculator and also wanted to see if you can even design one. Subtasks: Create a class called Calculator. Your class shall have 1 constructor and 4 methods, namely add, subtract, multiply and divide. Now, create an object of your class. After creating an object, it should print “Let’s Calculate!” Then take 3 inputs from the user: first value, operator, second value 5. Now based on the given operator, call the required method and…

Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…
