Chain of responsibility design pattern

import java.util.*;
import java.time.*;

/*
 * Client -> request handler 1 -> request handler 2 -> request handler 3
 * Withraw 2000rs from atm -> 2000 rs handler -> 500 rs handler -> 100 rs handler and so on
 *
 * chain of responsibility : validate username -> check atm pin -> then check atm expiry date-> check user balance -> then give money ...
 *
 */

/*
 * basically means ki agar info logging ka call aae and info logger na mile to
 * error logging kardo
 *
