83. JAVA Program to convert given Integer into Roman Letter.
How does this program work?
- This program is used to convert given Integer into Roman Letter using java.
Here is the code
//To convert given Number into Roman letter
import java.util.HashMap;import java.util.Scanner;
public class roman
{
private static int[] bases = { 1000, 900, 500, 400, 100, 90, 50, 40, 10, 9, 5, 4, 1 };
private static HashMap < Integer, String > map = new HashMap < Integer, String>();
private static void setup()
{
map.put(1, "I" );
map.put(4, "IV" );
map.put(5, "V" );
map.put(9, "IX" );
map.put(10, "X" );
map.put(40, "XL" );
map.put(50, "L" );
map.put(90, "XC" );
map.put(100, "C" );
map.put(400, "CD" );
map.put(500, "D" );
map.put(900, "CM" );
map.put(1000, "M" );
}
public String intToRoman(int num)
{
setup();
String result = new String();
for(int i : bases)
{
while(num >= i)
{
result += map.get(i);
num -= i;
}
}
return result;
}public static void main(String arg[])
{
System.out.println("Enter the number : ");
Scanner sc = new Scanner(System.in);
int no = sc.nextInt();
roman in = new roman();
int value=no;
String sd = in.intToRoman(value);
System.out.println(value+" convert to Roman letter is ---> " + sd);
}
}
