list<jlabel> lotteryboxes = new arraylist<>();  list<jlabel> getselectednumbers() {     list<jlabel> numbers = new arraylist<>();     iterator<jlabel> = lotteryboxes.iterator();     while (it.hasnext()) {         jlabel nr = it.next();         if (nr.iscursorset()) {             numbers.add(nr);             selected.settext("selected: " + nr);         }         return numbers;     } 

i not know do, please give me answers.

if create labels in loop, can add handler them. either same handler checks of labels clicked, or separate handler each one.

here there separate handler each , labels put array can use them later (outside loop).

int numberoflabels = 34; jlabel[] labels = new jlabel[numberoflabels]; (int index=0; index<numberoflabels; index++) {     string labeltext = "" + (index + 1);     final jlabel label = new jlabel(labeltext));     final int labelnumber = index + 1;     label.addmouselistener(new mouseadapter() {         public void mouseclicked(mouseevent e) {             // something, can use "label" in here, eg:             selected.settext(label.gettext());             // have access number in "labelnumber"         }     });     somepanel.add(label);     labels[index] = label; // save label if need access later }
