OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step

- CSC 260L Laboratory 6 Design & Analysis Class 3 void romanType::romanToPositiveInteger() { int sum - ej int length - romanlum. length(); int i Write a program that converts a number entered in Roman numerals to a positive integer. Your program int previous - 1008; should consist of a class, say romanType. The class roman'Type consists of: for (i - e i« length, i++) { switch (romantNun [i]) { case 'M": sum - 1000; 1. Two private member variables: romanNum(type string) and num(type int) to store an ; integer in roman format and decimal format. 2. Four functions: if (previous < 1000) sun 2* previous; previous - 1000; break case 'D': sum + see; if (previous < soe) sum -- 2* previous previous - 5ee, break case 'C'! sum 100 if (previous < 100) a. setRoman which take a string as parameter and assign it to the member 'roamNum'. This function is a void function. b. roman'ToPositiveInteger () which takes no parameter and converts the carresponding roman string|called 'romanNum) to the private…C++ Friend function concepts Do not use operator overloading Create a class User with private member variables "id". In the class define a function increment_user_id() which will increment the id and return it as well. Create another method "void show_Id()" to show the id for a particular object. Create a constructor of User class where increment the Id by calling the increment_user_id() method for every new object . Finally create two objects of the class and print their corresponding id's on console.Software Requirements: • Latest version of NetBeans IDE • Java Development Kit (JDK) 8 Procedure: 1. our progras from rhFactor non-static and private. Remove the constructor with two (2) parameters. 2o upply uncapsutation Make bloodType and 2. The names of the public setter and getter methods should be: • setBloodType() • setRhFactor() getBlood Type() getRhFactor() 3. Use the setter methods to accept user input. 4. Display the values by calling the getter methods. Sample Output: Enter blood type of patient: Enter the Rhesus factor (+ or -): O+ is added to the blood bank. Enter blood type of patient: B Enter the Rhesus factor (+ or -): B- is added to the blood bank.
- Sanchez Construction Loan Co. makes loans of up to R100,000 for construction projects. There aretwo categories of Loans—those to businesses and those to individual applicants. Write anapplication that tracks all new construction loans. The application also must calculate the totalamount owed at the due date (original loan amount + loan fee). The application should includethe following classes:•• Loan—A public abstract class that implements the LoanConstants interface. A Loan includes aloan number, customer last name, amount of loan, interest rate, and term. The constructor requiresdata for each of the fields except interest rate. Do not allow loan amounts greater than R100,000.Force any loan term that is not one of the three defined in the LoanConstants class to a short-term,1-year loan. Create a toString() method that displays all the loan data.•• LoanConstants—A public interface class.

The Essay class should include member constants MIN_WORDS and MAX_WORDS. An essay should be between 1500 and 3000 words. The Essay class should also contain a member method validLength(), which returns true when the Essay object contains between MIN_WORDS and MAX_WORDS and false otherwise.

- array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.18. If a class is declared as final, the incorrect statement is (). A. Indicates that this class is final B. Indicates that this class is a root class C. Methods in this class cannot be overridden D. Variables in this class cannot be hidden 19. In the following description of polymorphism, the incorrect one is (). A. Polymorphism refers to "one definition, multiple implementations" B. There are three types of polymorphism: dynamic polymorphism, static polymorphism, and default polymorphism C. Polymorphism is not used to speed up code D. Polymorphism is one of the core characteristics of OOP 20. In Java, two interfaces B and C have been defined. To define a class that implements these two interfaces, the correct statement is ( ). A. interface A extends B,C B. interface A implements B,C C. class A implements B,C D. class A extends B,C 21.
