java - The use of executor.shutdown() -


look @ following piece of code:

     public void pinger()      {         scheduledthreadpoolexecutor executor = new scheduledthreadpoolexecutor(1);         executor.scheduleatfixedrate(runnable, start, rate, timeunit.seconds);         executor.shutdown();      }

is there use of writing shutdown command in case? different clients create own runnable objects , invoke function.

when shutdown executor, no new task accepted. since create new 1 inside pinger method every task has own executor. shutdown write free resource once corrent task terminated.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
