    Why generic exception is not better than individual exceptions?

      Hi Forum,

      I am new to Java and currently I am learning how to handle exceptions in Java. I read some articles and they mentioned that generic exceptions are not good and each exception should be captured individually. For example
       catch (Exception e ) {
           System.out.println("Exception: " + e.getMessage());
      is a bad way of capturing rather one should capture like
      catch (FileNotFoundException fnf ) {
           System.out.println("Exception: " + fnf.getMessage());
      catch (NullPointerException npe) {
           System.out.println("Exception: " + npe.getMessage());
      catch (IOException ioe ) {
           System.out.println("Exception: " + ioe.getMessage());
      if these are all the ones that can occur.

      Thanks in advance.
