java: Please use java code to reverse the string, such as: input abcde, output edcba.

public class Main{

    public static void main(String[] args) {
        String a="cdsjcnjanadbcds";
        System.out.println(reverse(a));
    }
    public static String reverse(String s){
        StringBuilder sb=new StringBuilder();
        for (int i = s.length()-1; i >=0 ; i--) {
            sb.append(s.charAt(i));
        }
        return sb.toString();
    }
}
