- 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…Consider the scenario of a Pharmacy Management System. The following UML Class diagram shows a hierarchy of some of the classes in the system. (Shown in Picture) The StateManager Interface is a generic interface which has two methods changeState (boolean : status). This method is used to change the status of InvoiceItem and PrescriptionItem. The possible status for InvoiceItem can be (Available – true or Unavailable - false), whereas PrescriptionItem has status (Recommended-true or Prohibited – false) passed to the method as an argument. The reset () method sets the default value for both InvoiceItem and PrescriptionItem. The Item class is self-explanatory. It implements the StateManager interface, and has toString method which prints the information in the following format. "Item Name: <<name>> (<<id>>)” e.g. Item Name: Panadol (223) Two classes PrescriptionItem and InvoiceItem are inherited from Item class representing the items that can be sold with…write a class implementation using C++ from the given class diagram TAKE NOTEOF THE FF SPECIFICATIONS: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. Please note that the deactivated voter account must be still part of the “object”. Test all the functions by making calls. this should be the sample result. Please use simple codes only.
- 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…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.

The student has the following properties:student name, number, SSN and GPA. Similarly, the course has the following properties: course name,course number, credit hours and a set of students who are currently registering on the course.Implement the above system taking into account the following requirements:1. In course, the number of students that are registering this course is decided at the time wheninstantiating the course object.2. Assume that student1 and student2 are two objects of type student, write a code that enablesyou to write: if (student1.isequal (student2)). Where student1, student12 arestudent objects.
