String reverse

Hi am trying to reverse a string

Here is my code:

import java.util.*;
 
public class ReverseLettersInString {
	public static void main (String[] args){
		Scanner in = new Scanner (System.in);
		String s;
		System.out.printf ("Enter string\n");
		s = in.nextLine();
 
		for (int i= s.length()-1; i>0; i--)
		{
			System.out.printf ("%c", s.charAt(i));
		}
	}
 
}

PROGRAM OUTPUT:
Enter string
me
e

The program returns e instead of em

Look at the loop closely. Considering the input of the String 'me' - the length of 'me' is 2, the index of 'm' is 0, and 'e' is 1...will the loop ever reach 'm'?

Thanks a lot, I changed i>0 to i>=0 and it worked!
