Exercise 1: Design an interface named ConversionFactors that declare instance variable called inTOMm with value 25.3, ounToGram with value 28.35, and pounToGram with value 453.59. Besides, design an interface named Conversions that contains method declarations for inToMm, ounToGram and pounToGram. All the methods return a double type value and do not has parameter. For an example, method inToMm converts inches to millimeters using the formula inches inToMm. Next, design a class named myClass that implements * ConversionFactors and Conversions.myClass has instance variable called pounds, inches, and ounces, constructor and implements all the methods declared in Conversions interface. The following is the output example when creating myClass object by initializing 50, 25, 100 to pounds, inches, and ounces respectively: 50.0 pounds is equal to 22679.5 gran 100.0 ounces is equal to 2835.0 gram 25.0 inches is equal to 632.5 milimeter Draw UML diagrams that involves myClass, ConversionFactors, and Conversion.

1. Create a properly encapsulated class named Person that has the following: A String instance variable called name. A constructor that takes a String parameter and sets the instance variable. A properly named getter for the instance variable. A correctly overrided equals method which returns true if the name instance variable of the parameter and the reference variable calling the method are equal. (Do not forget the null and class type checks!) Compile your Person class. 2. Create a properly encapsulated class named Employee that inherits from Person and has the following: ● ● ● A String instance variable called office (e.g. "LWH 2222"). A String instance variable called hourlywage (e.g. "$45.15"). A constructor that takes three Strings as parameters for name, office, and hourlyWage and sets the instance variables of both the parent class and the Employee class. An overridden toString method that returns the concatenation of name and hourlyWage instance variables (separated by a…
A. Build a class named car. This class is defined as follows: It has the fields: Car ID, Car model, Car make, Car color, Car year. Build a constructor that accepts the five parameters (Car ID, Car model, Car make, Car color, Car year). Override the method toString() to return the string representation of Car ID, Car model, Car make, Car color, Car year. Build a method named display to print the values returned by toString() method. Override the equals() method to compare the Car model, Car make, Car color of two Car objects. The method returns true if all the values of these fields are the same, and false otherwise. In the equals method you must check the following: a. If you compare the Car object to itself, return true.! b. If you compare car object with another car object return true, otherwise return false. Hint use : instanceof operator for this purpose. Override the hashcode() method to return same hash codes for objects that are equal according to the equals() method you built…
Which is true? Group of answer choices A class can implement multiple interfaces A class can inherit from multiple classes A class can implement only one interface An interface can implement multiple classes
Given the class declaration and instance method definitions and based on what you learned about separate compilation, what would be a good name for the header file containing the declaration, and what would be a good name for the source file containing the instance method definitions? // This is the class declaration class Rectangle { public: Rectangle(double width, double height); double get_height() const; double get_width() const; double get_area() const; private: double _width; double _height; }; // This is the instance method definition Rectangle::Rectangle(double width, double height) { _width = width; _height = height; } double Rectangle::get_height() const { return _height; } double Rectangle::get_width() const { return _width; } double Rectangle::get_area() const { return _width * _height; }

Write C# code to perform the following: Create TrainingStudent class & implement variables, make sure about traiffPoint input range using TraiffPoint property. Create two constructors as follows: [both constructors should increment the class variable appropriately] The first is a default constructor that has no parameters and sets the instance variables to either "not known" for the strings, 20 for the integer. The second takes 3 parameters, one for each of the instance variables. Create ShortTraining & LongTraining classes (extending TrainingStudent) & implement variables month & year & make sure about Month & Year range inside property. After Implementation Verify & validate your Logic using following main Code. TrainingStudent t = new TrainingStudent(); t.Print(); // Not Known – Not Known – 20TP TrainingStudent t2 = new TrainingStudent(“12”, “akram”,150); t2.Print(); // 12 –…

This example asks you to write an interface. Then define three classes that implement this interface. 1) Create an interface Discount Policy. It should have a single abstract method called computeDiscount that will return the discount for the purchase of a given number of a single item. The method has two parameters, count and item Cost. This interface has no other method. 2) Define a class Bulk Discount that implements the interface Discount Policy, as de- scribed above. It should have a constructor that has two parameters, minimum and percent. It should define the method computeDiscount so that if the quantity purchased of an item is more than minimum, the discount is percent percent. 3) Define another class Buy NItemsGetOneFree that implements Discount Policy as de- scribed in part 1. The class should have a constructor that has a single parameter n. In addition, the class should define the method computeDiscount so that every nth item is free. For ex- ample, the following table…
