Printing the digits of a number in reverse order

Question

Can someone please help me solve this? The number should be variable and not constant. The output should be:

Timestamping In 6 Digit
8
5
6
3
0
1
Average In 6 Digit         


        

Answer 1

What do you really want to do? Print two integer numbers reversed? Then you should say so.

public static String reverseDigits(int i) {
  StringBuilder sb = new StringBuilder();
  sb.append(i);
  sb.reverse();
  return sb.toString();
}

...
System.out.println(reverseDigits(1234567));
...

Answer 2

If you just want to reverse a number then here you go

public String reverseNum(Integer i)
{
return new StringBuilder(i.toString()).reverse();
}
