Question

Code:

    outerMethod {
        @Override
        public void run() {
                innerMethod throws IOException
                }
    }

Method that exceuted in thread throws checked exception – IOException.
I need to handle this exception in main thread.
Like:

outerMethod() throws IOException
   {
        @Override
        public void run() {
                innerMethod() throws IOException
                }
    }

Is this possible? If no, what would be a better way to do this?

Thanks.

Use FutureTask http://docs.oracle.com/javase/6/docs/api/java/util/concurrent/FutureTask.html#get%28%29 . It’s get methods will encapsulate any exceptions from the task that might have run on another thread.

ExecutionException: Exception thrown when attempting to retrieve the result of a task that aborted by throwing an exception. This exception can be inspected using the Throwable.getCause() method.
