通过追加到StringBuilder来反转字符串

public class StringsDemo {

    public static void main(String[] args) {

        String palindrome = "Dot saw I was Tod";

        int len = palindrome.length();//时代Java - nowjava.com

        StringBuilder dest = new StringBuilder(len);

        for (int i = (len - 1); i >= 0; i--) {

            dest.append(palindrome.charAt(i));

        }

        System.out.format("%s%n", dest.toString());

    }

}
