String reverse without using reverse method

I am providing two ways:
public class StringReverse{
 public static void main(String [] args){
    String s =  "SURESH";
    String reverseString = "";
    int len = s.length();
    for(int i=len-1;i>=0;i--) {
    reverseString=reverseString+s.charAt(i);
    System.out.println(reverseString);
    }
 }
}
=================================
public class StringReverse{
   public static void main(String [] args){
      String s =  "SURESH";
      char[] charArray = s.toCharArray();
      for(int i=charArray.length-1;i>=0;i--){
System.out.print(charArray[i]);
}
   }
}

OUT PUT:
