Java program to Convert Integer Number to Roman Number.{By Hottest Way).💣👌 Please Check out .


class Main {
public static void main(String[] args) {
int num;
System.out.println("please the number below 5000");
Scanner obj = new Scanner(System.in);
num = obj.nextInt();
String str = String.valueOf(num);
char []arr = str.toCharArray();
int len = str.length();
int count[] = new int[10];
for(int i=0;i<len;i++){
count[i] = (int)arr[i]-48;    }
String ones[] = new String[]{"","I","II","III","IV","V","VI","VII","VIII",
"IX","X"};
String tens[] = new String[]{"","X","XX","XXX","XL","L","LX","LXX","LXXX",
"XC","C"};
String hundred[] = new String[]{"","C","CC","CCC","CD","D","DC","DCC",
"DCCC","CM","M"};

String thousand[] = new String[]{"","M","MM","MMM","MMMM","~V"};
if(len==4 && num<=5000){
String romancounting = thousand[count[0]]+ hundred[count[1]] + tens[count[2]] + ones[count[3]];
System.out.println(romancounting);
}
else if(len==3) {
String romancounting = hundred[count[0]]+
tens[count[1]]+ones[count[2]];
System.out.println(romancounting);  }
else if(len==2){
String romancounting = tens[count[0]]+
ones[count[1]];
System.out.println(romancounting);   }
else     {
System.out.println("Sorrt But number is invalid!
OutOfRange👌");
} } }
