[Java lista] szalkezeles

[Zoltan Mozes]

valóban úgy van ahogy Laci mondta

a szál run()-jában kell gondoskodni a többszörös végrehajtásról.

Nehogy azzal kísérletezz hogy magát a start()-ot hívod többször, csak ennyit akartam mondani a Laci által helyesen elmondottakhoz.

Bocsánat, egykiegészítés:

szálat NEM lehet újraindítani:

"
When Execution Ends
When the run() method returns, the thread has finished its task and is considered dead. There
is no way out of this state. Once a thread is dead, it cannot be started again; if you want the
thread's task to be performed again, you have to construct and start a new thread instance. The
dead thread continues to exist; it is an object like any other object, and you can still access its
data and call its methods. You just can't make it run again. In other words,
 You can't restart a dead thread by calling its start() or run() methods.
 You can call other methods (besides start() and run()) of a dead thread.
The Thread methods include a method called stop(), which forcibly terminates a thread,
putting it into the dead state. This method is deprecated since JDK 1.2, because it can cause data
corruption or deadlock if you kill a thread that is in a critical section of code. Therefore, if a
thread might need to be killed from another thread, you should call interrupt() on it from the
killing method.

  Hali!

>átirtam a progit

>nincs start() metódus sem

Helyes. Es erted, hogy miert?

>a probléma sajnos még fent áll gondolom valahol máshol van a hiba

Igy van. Tovabbra sem szinkronizalsz. Java Utikalauz programozoknak,
217-257, szinkronizacio: 248

>bár az számomra érdekes, hogy miért az után blokkolódik a progi miután 
>lefutt a TimerTask ?

Ezert. Nem erdekes, csak total nem erted. En meg teged nem.

>direkt a TimerTask run metódusa után iratom ki, hogy 
>"lefutott.." ez után 
>vár néhány mp-t
>a futás magában gyorsan megtörténik miért nem fut tovább az a szál ami 
>közben tölti a táblát
>egyáltalán miért áll meg? 

Mert a run metodust egyszer futtatja a Thread, azert. Ha tobbszor
akarod futtatni a benne levo kodot, akkor azt egy ciklusba kell rakni.
Ez kiderulne:
- az elozo levelembol (leirtam)
- a javadocbol (belinkeltem)
- barmelyik normalis java konyvbol.

Neked fizetnek ezert? Most komolyan. Nem erezned jobban magad, ha e-mailek
helyett programot irhatnal? :)
