swing - how to get variable value from a java thread -


i have thread computes , generates 2 d array. need access value of 2 d array, when thread finished. how can that

        swingworker<integer, void> worker = new swingworker<integer, void>()         {             object[][] valuematrix = null;              @override             public integer doinbackground()             {                 try                 {                     valuematrix = dochemicalsynonyms(termsarray_1, termsarray_2, mview.getsavefilepath(), false, mview.getsheetname(), mview.getcategoryname(), mview.includepmids());                 }                 catch (exception e)                 {                     e.printstacktrace();                     return -1;                 }                 return 0;             }              @override             public void done()             {                 system.out.println(valuematrix[0][0]);             }         };         worker.execute(); 

dochemicalsynonyms functions generates valuematrix. how can access once thread complete, main class( global variable)

what should use done() method collect result thread. printing first value, can transfer thread use there.

beware done() invoked in edt, if need intensive operariton on it, thread necessary.
