 import java.util.*;

 public class MyException extends Exception {

     private static final Exception Exception = null;
     private static final Exception NullPointerException = null;

     public static void main(String[] args) {
         try {
             throw (NullPointerException);
         } catch (NullPointerException e) {
             System.out.println("@@@@@");
         } catch (Exception e) {
             System.out.println("$$$$");
         } finally{
             System.out.println("#####");
         }
