意外的错误

我有一个学校项目，我不应该开始直到星期一，而且这不是由于另外6周或更长的时间。我们正在用java创建一个程序来添加我们想要的数据库，我选择了游戏（标题，流派，平台，价格，数量（字符串，组合框，组合框，double，int）），我使用堆栈来添加所有的对象，但由于某种原因，我不能让它编译出于某种原因，我不断得到非常奇怪的错误。我的错误和代码分别在下面。意外的错误

添加了作业标签。 – 2012-02-16 07:38:45

它在那里，但有些人删除它。 – 2012-02-16 08:06:54

这一呼吁：

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

应该是某种方法，因为你想这样做，我每一个新的对象，因为它从你的代码看起来，为什么不将它移动到构造函数：

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); 
    } 
}

男人我讨厌它，当我做这样的愚蠢的错误;我想所有的学习过程。谢谢你，先生！ :) – 2012-02-16 07:33:44

它确实是学习过程的一部分。我想我们大多数人也是这样做的...... – MByD 2012-02-16 07:34:21

您需要先定义一个方法，然后在方法中写入相关代码。我没有透露太多，因为这是一个家庭工作项目。尝试阅读更多关于java的类和方法

你不能直接在你的代码中加入你的代码，你必须把它放到一个方法或构造函数中。
