我有一個GUI，主要是一項調查，當調查完成後，信息將被提取到一張表中，目前我無法獲取所有信息，我創建了一個叫做完成處理程序的Actionlistener附加到調查GUI按鈕「完成」，因此當完成按鈕被點擊時，它將提取所有信息並將其存儲到我的DataStorage類中。以下是我的調查GUI，actionListener類和數據存儲類。獲取來自不同JComponents的信息

問題是什麼？ – Jonas 2010-02-13 09:32:07
上面的gui有Jcomponents像Textfields，comboxes radiobuttons，一個登錄用戶需要填寫，我被困在如何提取所有數據後，用戶按下一個名爲Finish的按鈕，並將它們存儲到登錄的用戶對象我已嘗試將Handler添加到每個相應的小部件，因爲如果我不在調試它們時，它們在進行更改時不會得到響應，如從男性更改爲女性。 – sutoL 2010-02-13 13:44:28
