Java – how to reschedule tasks using scheduledexecutorservice?

I saw this in Java docs: scheduledatfixedrate

I don't want this to happen in my application Even if I see an exception, I always want the subsequent execution to happen and continue How to get this behavior from scheduledexecutorservice

Solution

Use try / catch to surround callable Call method or runnable Run method

For example:

public void run()
{
    try
    {
        // ... code
    }
    catch(final IOException ex)
    {
        // handle it
    }
    catch(final RuntimeException ex)
    {
        // handle it
    }
    catch(final Exception ex)
    {
        // handle it
    }
    catch(final Error ex)
    {
        // handle it
    }
    catch(final Throwable ex)
    {
        // handle it
    }
}

Note that capturing anything other than what the compiler tells you (IOException in my example) is not a good idea, but sometimes it sounds like one of them. If you handle it correctly, it can be solved

Remember, things like errors are very bad - virtual machines are out of memory, etc., so be careful how you deal with them (that's why I separate them into my own handlers instead of just catching (the last throwable Ex) and nothing else)
