Recursion - digits in reverse order

Question

I need to implement a recursive method printDigits that takes an integer num as a parameter and prints its digits in reverse order, one digit per line.

This is what

Answer 1

Here you go :

static String reverseDigits(int n)
{
    String N = "";
   if ( n== 0)
       return N;
   else
   {
       N += n%10;
       return N + reverseDigits(n/= 10);
   }            
}

This is of course returned as String.

If you want it as int all you have to do is parse it using Integer.parseInt()
