Implement the classes according to the given class diagram. It shows both the composition and aggregation relationships. Driver has a Vehicle and Engine is a part of that Vehicle. [Note: consider the necessary data members, constructors, destructors and member functions accordingly] Note: solve as soon as possible use C++ LANGUAGE Class diagram is given
Justify why it is desirable to have accessors to private types rather than making the types public for the following three reasons.
Let's enumerate the elements involved in Generalization of object factories. This gives us the intellectual workout necessary for putting together a generic object factory.• Concrete product. A factory delivers some product in the form of an object.• Abstract product. Products inherit a base type (in our example, Shape). A product is an object whose type belongs to a hierarchy. The base type of the hierarchy is the abstract product. The factory behaves polymorphically in the sense that it returns a pointer to the abstract product,without conveying knowledge of the concrete product type.• Product type identifier. This is the object that identifies the type of the concrete product. As discussed, you have to have a type identifier to create a product because of the static C++ type system.• Product creator. The function or functor is specialized for creating exactly one type of object. We modeled the product creator using a pointer to function.
Abstract data types are the hardest to grasp (ADTs). Are ADTS beneficial? Does heredity fix problems?
We wish to implement a system that allows the management of Employees and Students. As a first step. you need to implement the above UML diagrams Notes: . ZOOM . PERSON, EMPLOYEE and STUDENT should be public static constants The no-arg constructor will initialize ID, firstName and lastName to their respective null values. It will set personType to PERSON, and sortorder to LAST_NAME The overloaded constructor will assign each parameter to its respective field. sortorder will also be set to LAST_NAME toString() will output type, ID, firstName and lastName, all tab separated. This is an override method equals() will compare if the current object and the parameter contain the same values. This is an override method compareTo() compares the current object and the parameter. This is an override method. It will be used to sort objects Needs the Comparable interface O Will only compare fields depending on the sortorder. For example, if the sortorder is TYPE, it should then compare the…
Explain the distinction between implicit and explicit parametric polymorphism. What are their comparative advantages?
Explain why it is preferable to have accessors to private types rather than making the types public, keeping in mind the three reasons that are given below.
Consider the following example depicted by UML diagram, where the Figure is an abstract class andCompareObjects is an interface receiving a generic data type T. Both classes Rectangle and Triangle haveextended the abstract class Figure and implemented the interface CompareObjects. As a consequence, boththe classes have to override the abstract methods area and compareObj. One example program to performeverything has been given below for your clear understanding.In the example program, class Rectangle has overridden the area method according to the formula forcalculating the area of a Rectangle. It has implemented the CompareObjects interface and replaced the type Tby Rectangle. So, the compareObj method receives another Rectangle object for comparison with the callingRectangle object. Here, the compareObj method is overridden to compare two Rectangle objects based ontheir area. The compareObj method will return 0 if the two Rectangle objects have same area, 1 if the invokingobject has…
Give two other terms, each, for base class and derived class. Explain why generics may be useful in an object-oriented language, despite the extensive polymorphism already provided by inheritance.
Problem B Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…
