Ask User To Enter Number From 1 To 10 And Program Will Display Roman Numeral

I am trying to write a program that asks the user to enter a number from 1 through 10 and then the program will display the roman numeral for that number.

I am also adding a error message in which i haven't yet because im still trying to figure out how to the program will do the roman numeral.'

I have used the if and else if. but when i input a number it just repeats the number back to me.

The program cimpiles but it doesn't do what i want. here is what i have so far. how can i get the program to display the roman numeral after the number is entered.

import javax.swing.JOptionPane;
public class Romannumeral
{
public static void main(String[] args)
{
double number;
 
[Code] .....
