@Override 注解的问题

发布于 2024-10-08 00:46:16 字数 1056 浏览 2 评论 0原文

我正在制作一个类似于 Banko 小程序的 Java 应用程序。当我点击“public void init()”方法时，我进展顺利。当我完成后，除此之外的所有内容都已编译完毕。它告诉我添加 @Override 注释。我尝试过，但每当我这样做时，无论我把它放在哪里，编译器都会失败并出现以下错误：

找不到符号

符号：类覆盖

位置：类aBomb.Bomb

我不知道什么可能会阻止应用程序正确执行。 :| 如果您在我下面编写的代码中发现您认为应该更改的内容，请告诉我。我对 Java 还比较陌生:( 代码：

public void init() {
    BorderLayout border = new BorderLayout();
    setLayout(border);

    JPanel top = new JPanel();
    JLabel moneyLabel = new JLabel("Money : $");
    moneyField = new JTextField("", 8);
    moneyField.setEditable(false);
    JLabel foundLabel = new JLabel("Found: ");
    foundField = new JTextField("", 8);
    foundField.setEditable(false);

    restart = new JButton("Restart");
    restart.addActionListener(this);
    top.add(moneyLabel);
    top.add(moneyField);
    top.add(foundLabel);
    top.add(foundField);
    top.add(restart);
    add(top, BorderLayout.NORTH);

    board = new Board(this, ROW_COUNT, COLUMN_COUNT, BOMB_COUNT);
    add(board, BorderLayout.CENTER);
    setup();
    setVisible(true);
}

原文

I am making a Java application similar to that of the Banko applet. I was coming along just fine when I hit the "public void init()" method. When I was finished, everything compiled except for that. It told me to add an @Override annotation. I tried that, but whenever I do, regardless of where I put it, the compiler fails with the following error:

cannot find symbol

symbol: class Overrides

location: class aBomb.Bomb

I have no idea what could be preventing the application from executing properly. :|
If you find something in the code I have written below that you think should be changed, please tell me. I'm relatively new to Java :(
Code:

public void init() {
    BorderLayout border = new BorderLayout();
    setLayout(border);

    JPanel top = new JPanel();
    JLabel moneyLabel = new JLabel("Money : $");
    moneyField = new JTextField("", 8);
    moneyField.setEditable(false);
    JLabel foundLabel = new JLabel("Found: ");
    foundField = new JTextField("", 8);
    foundField.setEditable(false);

    restart = new JButton("Restart");
    restart.addActionListener(this);
    top.add(moneyLabel);
    top.add(moneyField);
    top.add(foundLabel);
    top.add(foundField);
    top.add(restart);
    add(top, BorderLayout.NORTH);

    board = new Board(this, ROW_COUNT, COLUMN_COUNT, BOMB_COUNT);
    add(board, BorderLayout.CENTER);
    setup();
    setVisible(true);
}

首先，如果您至少包含类定义（“公共类...”部分），那将真正有帮助。

我猜您有一个名为 aBomb 的类，它扩展了来自 Applet：

public class aBomb extends Applet {
//...
    // Here's the init method; the @Override goes
    // immediately before the declaration.
    @Override
    public void init() {
//...
};

错误消息看起来好像您将 @Override 拼写为 @Overrides。

First of all, it would really help if you'd included at least the class definition (the "public class..." part.)

I'm guessing that you have a class named aBomb which extends from Applet:

public class aBomb extends Applet {
//...
    // Here's the init method; the @Override goes
    // immediately before the declaration.
    @Override
    public void init() {
//...
};

The error message looks as if you misspelled @Override as @Overrides.
