“Rethrow” to next catch clause

Question

If there is a try-catch with mutiple catch-blocks, is there way to rethrow an exception to next (not underlaying) catch-clause?

Example:

try {

  // some exception can occur here

} catch (MyException ex) {

  // do something specific

  // rethrow ex to next catch

} catch (Exception ex) {

  // do logging stuff and other things to clean everything up
}

When a MyException is thrown, I want to handle the specific stuff to that exception but then I want to handle exceptions in general ( catch (Exception ex) ).

I don't want to use a finally-block and Java 7 Multi-catch is also no help here.

Any ideas how to handle this, I want to avoid redundant stuff in each catch-block. Is it better to catch Exception only and then use instanceof for my specific stuff?

Thanks.

Answer 1

public void doStuff()
{
   try
   {

     // some exception can occur here

   } catch (MyException ex){

     // do something specific

     cleanupAfterException(ex);

   } catch (Exception ex) {

     cleanupAfterException(ex);
   }
}

private void cleanupAfterException(Exception ex)
{
   //Do your thing!
}

I presume something like this would do?

You might want to try something like this:

try
{

}
catch(Exception ex)
{
    if(ex instanceof MyException)
    {
        // Do your specific stuff.
    }
    // Handle your normal stuff.
}

Answer 3

You could just nest your try statements:

try {
  try {

    // some exception can occur here

  } catch (MyException ex) {

    // do something specific

    // rethrow ex to next catch

  }
}  catch (Exception ex) {

  // do logging stuff and other things to clean everything up
}

Although I worry this is what you mean when you say " (not underlaying) "?

Answer 4

You can try multiple try catch:

try {

} catch(MyException ex) {
    try {

    } catch(Exception ex) {

    }
}

Answer 5

Surely this is what functions are for?

try {
    doStuff();
} catch ( MyException e ) {
    doMyExceptionStuff();
    doGeneralExceptionStuff();
    throw e;
} catch ( Exception e ) {
    doGeneralExceptionStuff();
}
