意外的錯誤

我有一個學校項目，我不應該開始直到星期一，而且這不是由於另外6周或更長的時間。我們正在用java創建一個程序來添加我們想要的數據庫，我選擇了遊戲（標題，流派，平臺，價格，數量（字符串，組合框，組合框，double，int）），我使用堆棧來添加所有的對象，但由於某種原因，我不能讓它編譯出於某種原因，我不斷得到非常奇怪的錯誤。我的錯誤和代碼分別在下面。意外的錯誤

添加了作業標籤。 – 2012-02-16 07:38:45

它在那裏，但有些人刪除它。 – 2012-02-16 08:06:54

這一呼籲：

gamesStack.push(new Game("[Halo: Reach]", 3, 1, 108.00, 2));

應該是某種方法，因爲你想這樣做，我每一個新的對象，因爲它從你的代碼看起來，爲什麼不將它移動到構造函數：

public class GameCombo extends JPanel { 
    ArrayList<Game> gamesList = new ArrayList<Game>(); 
    Stack<Game> gamesStack = new Stack<Game>(); 
    private JComboBox _gameBox; 

    public GameCombo() { 
     setLayout(new GridLayout(1,1,1,1)); 
     gamesStack.push(new Game("[Halo: Reach]", 3, 1, 108.00, 2)); 
     _gameBox = new JComboBox(gamesStack); 
     add(_gameBox); 
    } 
}

男人我討厭它，當我做這樣的愚蠢的錯誤;我想所有的學習過程。謝謝你，先生！ :) – 2012-02-16 07:33:44

它確實是學習過程的一部分。我想我們大多數人也是這樣做的...... – MByD 2012-02-16 07:34:21

您需要先定義一個方法，然後在方法中寫入相關代碼。我沒有透露太多，因爲這是一個家庭工作項目。嘗試閱讀更多關於java的類和方法

你不能直接在你的代碼中加入你的代碼，你必須把它放到一個方法或構造函數中。
