java - How can i make the JLabel change through different threads without a final String? -

i know seems question asked , answered time , again, after combing through stack overflow hours couldn't solve problem. sorry in advance if i'm missing obvious.

i need change jlable's text each time thread starts, , again when thread finishes. simply, i'm trying show number of threads running.

jobqueueview static , final jlabel. main jframe has jlabel. jobqueue static int.

at start of each thread:

jobqueue += 1; refreshqueue(); 

at end of each thread:

jobqueue -= 1;refreshqueue(); 

and finally

public void refreshqueue() {         eventqueue.invokelater(new runnable() {             @override             public void run() {                 new main().jobqueueview.settext(integer.tostring(jobqueue));             }         });      } 

this doesn't work. ideas? thanks

edit : per instructions of andrew thompson swing jlabel text change on running application : on button click event

can change text of label thread in java? : has make string final. cant.

update jlabel thread : uses timers, need thread count

jlabel on jpanel doesn't update when settext method : tried given solutions. didn't work

thread , jlabel in swing- not working properly : more button clicks different solutions. still didnt work

it seems creating new frame every time.

new main().jobqueueview.settext(integer.tostring(jobqueuecount ));

so have multiple frames 1 static label. may cause problem. access jobqueueview through static way below.

main.jobqueueview.settext(integer.tostring(jobqueuecount ));
