multithreading - SwingWorker threads in Java -

i'm working swing @ minute , i've run bit of problem, realize it's not possible execute swingworker thread more once http://docs.oracle.com/javase/tutorial/uiswing/concurrency/worker.html.

my question is possible create new instance of same swingworker thread? in code here i've called worker thread 'worker'

swingworker<void, void> worker = new swingworker<void, void>(){   public void doinbackground(){    } }; 

is possible create more 1 instance of thread can call more once? i've tried like

(new swingworker<void, void> worker).execute(); 

but doesn't seem work. appreicated!

what problem creating new swingworker every time need it?

if need store state in instance needs run many times can use runnable or callable interfaces , give swingworker execution. have create swingworker every time, runnable or callable instance can same.

in example below worker instance created every time runnable instances same.

class foo {   private final runnable executeinbackground;   private final runnable executeindone;    public foo(runnable done, runnable background) {      executeindone = done;      executeinbackground = background;   }    public void execute() {      swingworker<void, void> worker = new swingworker<void, void>() {         public void doinbackground() {            executeinbackground.run();         }          public void done() {            executeindone.run();         }      };      worker.execute();   } }
