java - How to use and create a daemon thread and optimal utilization with Swing -

i creating blackjack game high school programming class , need method tracks card values , bets run in background. research on website revealed daemon threads answer. if not true, please provide me suitable alternative , include examples of how use , create alternative.

my problem not understand how create daemon thread. appreciate explanation , example of how use , create daemon thread.

there 1 more problem, program, created resource class contains code dealer. players subclasses of dealer , subclasses of jpanel. in subject, blackjack game uses swing display game , "optimal utilization" comes in. have application file in dealer , player objects entered so:

    public class panelproject extends jpanel {     private playerboxclubs playerone;    private playerboxhearts playertwo;      private playerboxspades playerthree;    private dealerboxdiamonds dealerone;      public panelproject()    setlayout(new borderlayout());    jpanel centersub = new jpanel();   centersub.setlayout(new flowlayout());   add(centersub, borderlayout.south);    playerone = new playerboxclubs();   add(playerone, borderlayout.west);    playertwo = new playerboxhearts();   add(playertwo, borderlayout.center);    playerthree = new playerboxspades();   add(playerthree, borderlayout.east);       dealerone = new dealerboxdiamonds();   add(dealerone, borderlayout.north);    jbutton quit = new jbutton("quit");   quit.addactionlistener(new quitlistener());   centersub.add(quit, borderlayout.south);    }    

so, second question this: should place daemon thread, in application file, in dealer class (which superclass players) or somewhere else?

thread t = new thread(new runnable() {     public void run() {        // interesting background tasks, in while(running) loop.     } });  // next line answer question t.setdaemon(true);  t.start(); 

documentation

the difference between regular thread , daemon thread jvm happily exit if threads running marked daemon.

answering "where place it" harder, depends on structure have, , how work you're going in run() method. broadly, more work does, more should in own file/class (the 2 more or less same thing in java).
