Catch all exceptions within a thread

Question

Below is the code I have developed for a thread.

   int i;
    Thread thread = new Thread()
    {
        @Override
        public void run() {
            try {
                while(true) {
                    sleep(10000);
                    i++
                }
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    };

    thread.start();

Is there any possible way I can use any other catch or exception to catch all possible crushes within it? Thank you in advance!

You can have an `Error` or an `Exception` (InterruptedException inherits from Exception). So if you catch those, you catch everything. That said, a `while` in itself won't throw an Exception, the `sleep` will. — AntonH, Feb 02 '14 at 20:24

Just have catch (Exception ex) as well as catch (InterruptedException e)

With 2 try and catches? – zETO Feb 02 '14 at 20:22
No, you can add any number of catches to one try. – Tim B Feb 02 '14 at 20:22
You mean like `catch (InterruptedException, Exception e)`? – zETO Feb 02 '14 at 20:23
} catch (InterruptedException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } – Tim B Feb 02 '14 at 20:24
In general, capturing Exception is a **bad practice**, more info on this here http://stackoverflow.com/questions/21938/is-it-really-that-bad-to-catch-a-general-exception – nKn Feb 02 '14 at 20:34

It seems that only exception that block can throw,you have already handled but for safer side you can catch parent exception too i,e (Exception e) as below :

 try {
   //stuff
}
catch (InterruptedException e) {
     e.printStackTrace();
}
catch (Exception e) {
      e.printStackTrace();
}

@NKN yes i knw.but it will better to dnt leave any exception without any catch.You can add the exception catch after specific exception like in this case we are handling InterruptedException which can be caused by sleep but if other exception arise thn super class exception will handle – Kick Feb 02 '14 at 20:38
