Question

Write a program that converts a number entered in Roman numerals to decimal. Your program shoild consist of a class, say Roman. An object should do the following

-Store the number as a Roman numeral

-convert and store the numeral as a decimalthe

-print the number as a Roman numeral or decimal as requested by the user.

The decimal values of the Roman numerals are:

M 1000

D 500

C 100

L 50

x 10

V 5

I 1

-your class must contain the method romanToDecimal to convert a roman numeral into its equivalent decimal number

-test your program using: MCXIV, CCCLIX, and MCDLXVI

Explanation / Answer

import java.util.Scanner;

import java.io.*;

class Roman

{

int decimalno;

static char convertToDecimal;

public static void main(String args[])

{

roman a=new roman();

a.convertToDecimal(decimalno);

printRoman(romannumerical);

printDecimal(decimalNum);

}

public void convertToDecimal()

for converting roman to decimal

{

Scanner scn=new Scanner(System.in);

//creating a scanner function

int num=0;

int l=romannumerical.toUpperCase;

do

{

switch(convertToDecimal)

//given decimal values of the roman numerals

{

case ‘M’;

decimal +=1000;

break;

case ‘D’;

decimal +=500;

break;

case ‘C’;

decimal +=100;

break;

case ‘L’;

decimal +=50;

break;

case ‘X’;

decimal +=10;

break;

case ‘V’;

decimal +=5;

break;

case ‘I’;

decimal +=1;

break;

}

num++;

if(num<romannumerical.length());

//roman no length

{

decimalno=decimalno-no;

}

public static void printDecimal(int decimalno)

{

System.out.println(“Decimal number stored is”);

}

return 0;

}

Total values:-

MCDLXVI=1666

MCXIV=1116

CCCLIX=361
