我想要玩這個測驗，其中用戶有3個按鈕可供選擇。如果他們選擇了錯誤的答案，圖像炸彈就會出現，並立即自動改變爲下一個問題，如果他們選擇了核心問題，它也將改變爲下一個問題。但是，我的問題在於，我不知道我是否正確寫了我的if ... else語句。當我運行我的程序時，它不會更改爲下一個問題，並且沒有彈出圖像。我嘗試了很多方法來解決這個問題，但我仍然不能。我真的需要幫助。這裏是我的代碼和if ... else語句是從線244至388Java Swing遊戲TT

我不是向下選民，但有太多的代碼，翻閱。你需要更多地縮小問題的範圍。另外，如果這是作業，它應該被標記爲這樣。 – Bill 2012-02-05 05:47:06

另請參閱：正確縮進代碼。這是不可讀的。並且不要在事件派發線程中睡覺。閱讀http://docs.oracle.com/javase/6/docs/api/javax/swing/package-summary.html#threading and http://docs.oracle.com/javase/tutorial/uiswing/concurrency/index html的 – 2012-02-05 08:04:08

此代碼是太長的方式去通過它，但看了一下您的if報表顯示你正在檢查是否選擇了JButton。您可能需要的是將ActionListener添加到JButton，當用戶單擊JButton時將會調用這個ActionListener。在ActionListener中，您可以檢查是否給出了正確答案並繼續，或顯示「炸彈圖像」。

我建議你去看看Swing button tutorial，更具體的JButton part of the tutorial
