How to reverse a string

If the students are familiar with StringBuilder and StringBuffer, this question is very simple. Just reverse () is done. Is that correct?

Public class ReverseAString {public static void main (String [] args) {reverseInputString (Silent King II);} private static void reverseInputString (String input) {StringBuilder sb = new StringBuilder (input); String result = sb.reverse () .toString (); System.out.println (result);}}

The output is as follows:

The second king is silent.

To say more, StringBuffer and StringBuilder are very similar, the former is synchronous, all public methods add the synchronized keyword, can be used in multithreading; the latter is not synchronous, there is no synchronized keyword, so the performance is better, there is no concurrency requirements, then use StringBuilder.
