Exceptions - handle or declare rule

[Neha Jane]

Hi, I am trying to figure out why this piece of code which does not follow the handle-or-declare rule for exceptions, still compile

package com.neha.dumps;

public class ThrowExcept{

 static String s = "";
 public static void main(String[] args) {
 try { new ThrowExcept().doStuff(); }
 catch (Exception ex) { s += "c1 "; }
 System.out.println(s);
 }
 
void doStuff() {
 
 s += "t1 ";
 throw new NumberFormatException();
//Each method must either handle all checked exceptions by supplying a catch clause or
//list each unhandled checked exception as a thrown exception.

// but why this code works then?
 
}}

I hope the following article helps

http://java.sun.com/docs/books/jls/third_edition/html/exceptions.html

Look at section 11.2.5

Thanks a lot, Swastik. I dont know what led me to believe that NumberFormatException is a checked exception . Thanks again
