Can't get a simple Listener from a call to ComboBox in Vaadin 8.8.6

so the code is

*ArrayList viewcBoxListenList =(ArrayList) this.tdSelect.getViewSelectcBox().getListeners(ComboBox.ValueChangeEvent.class);
String o= viewcBoxListenList.get(0).getClass().getName();

now when I look at this String o i get: “com.vaadin.ui.ComboBox$$Lambda$109/2112187681” WHAT IS THIS??? and how do i get the listenet that happens to be arg$2 see attached pic


Before giving an answer, I would like to know what you are actually trying to accomplish?
