    Default Where does the exception go?

    I was doing some file handling recently and used the read() method of the FileInputStream class. The read() method throws an IOException. I came across code (and used it as well) that looks like the snippet below.
    Java Code:
    class fileRead{
    public static void main(String []a) throws IOException {
    //do file handling here and call read as well
    }
    }

    Now, what i want to know is that who handles the IOException? Is it the JVM? If yes, how does it do it. If no, please help.

    waiting...

    You are just throwing it. That means nobody handles it.

    If you write the code like this. You can handle it yourself:

    Java Code:
    class fileRead{
    public static void main(String []a) {
    
      try {
        //do file handling here and call read as well
      } catch(IOException e) {
    
        // handle your exception here
        e.printStackTrace();
    
      }
    }
    }

    Yes, it's. What is the best thing is handling the Exceptions. Normally what I have done is, catch all exceptions and put it into a log. So anytime latter I can check my error.
