    Default Question about exception handling - Help needed


    Could someone please breifly explain to me how I can handle exceptions from multiple classes, I cant find anything on the Internet that uses multiple classes.

    This is my catch statement to handle the exception within my Main program (below), however I want to handle an exception from another class. I understand I could use the .getMessage, but I have three classes and Im thinking this method will only work with one?

    Could someone please explain this to me?

    Catch within my Main program:
    Java Code:
    catch (Exception e) 
      System.err.println("Error: This is the Exception");

    I'm not sure what exactly do you want to do and what`s your question
    You can catch several exceptions and you can treat them differently
    Java Code:
    catch ( SQLException e )
    catch ( IOException e )
    In some cases, you want to do the same (e.g. logging the exception) in both cases, since Java 7 there is a multiple catch
    Java Code:
    catch ( SQLException | IOException e )
    If this doesn`t answer your question, maybe this helps: Lesson: Exceptions (The Java™ Tutorials > Essential Classes)

    Also, you want to printStackTrace() for the exception otherwise you won't have a clue where it was thrown from.
    Please do not ask for code as refusal often offends.
