Here's my solution:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Pr_01_ReverseString {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
String input = reader.readLine();
StringBuilder sb = new StringBuilder();
for (int i = input.length() - 1; i >= 0; i--) {//REVERSE ORDER
sb.append(input.charAt(i));
}
System.out.println(sb.toString());
}
}

Here's another without fori (for iteration):
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class Pr_01_ReverseString {
public static void main(String[] args) throws IOException {
try (BufferedReader bf = new BufferedReader(new InputStreamReader(System.in))) {
String a = bf.readLine();
StringBuilder b = new StringBuilder(a);
b.reverse();
System.out.println(b);
}
}
}
