actor - What other stuff can a Scala message tell you? -

-

given scala code below:

actor1 

 actor2 ! 'some_message

actor2

 receive (or react)   {     case 'some_message          sender ! 'ok_message

what info sender (actor1) can actor2 ?

how can tell actor message came if more 1 actor can send same message actor2 ? there metadata in sender can queried ?

am newcomer scala. patience.

...ken r

you can send actor sent original message part of message.

actor1

actor2 ! ("message", self)

actor2

receive (or react) {     case (string: string, sender: actor) => {         sender ! "another message"     } }

it should noted, though, should use send message original sender. calling function directly on actor cause sorts of terrible things happen!

i read in programming in scala today, if want more it, highly recommend book.

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
