Question

Create a Class for Roman Numerals Create a class called RomanNumeral which has two private instance variables: the String value of the Roman numeral, and an int for the Arabic value. It should have one argument constructor that takes a string as a parameter for the Roman numeral

Answer 1

The student's question is about creating a RomanNumeral class in a programming language, with two private instance variables to hold the Roman numeral's string and integer (Arabic) values and a constructor that initializes these variables.

Step-by-step explanation:

The student is asking to create a class in a programming language. This class called RomanNumeral will be designed to represent and manipulate Roman numerals. It requires two private instance variables, one for the String value of the Roman numeral and another for the corresponding int value in Arabic numerals. The class should have a constructor that takes a string as a parameter, representing the Roman numeral, and initializes the instance variables accordingly. Typically, this would involve not only storing the Roman numeral as a string but also converting it to its equivalent integer value.

Code Example:

public class RomanNumeral {
private String romanValue;
private int arabicValue;

public RomanNumeral(String romanValue) {
this.romanValue = romanValue;
this.arabicValue = convertToArabic(romanValue); }
private int convertToArabic(String roman) {
// Code for converting Roman numeral to Arabic numeral
} // Additional methods and logic}In this basic structure, convertToArabic would be a method for converting the Roman numeral string into an integer. Note that the actual implementation details depend on specific programming language features and conventions.
