java - 将数组中的数组中的选定字符串打印到 JTextField 数组上

Question

经过大量研究和反复试验，我无法找出如何准确地随机选择 String来自String Array在 Array的String Array s 并将其逐字符打印到 JTextField Array在JButton之后被按下。我知道这听起来……很尴尬，但不知道如何表达才能让它听起来不那么尴尬。所以，这是我制作的类，它使 JTextField Array在JPanel上。

 private Box[] boxes = new Box[SUIT_COUNT];
 private static int TEXT_FIELD_COUNT = 14;
 private static int SUIT_COUNT = 1;
 Color yungMoney = new Color(0, 180, 100);
 private static String puzzle;
 private static List<JTextField> field;
 private static String[][] puzzles = {wheelFoods, wheelHouse, wheelMovies, wheelPeople, wheelPlaces, wheelRandom};
 private static String[] puzzless;
 private static JPanel panel;

public letterBoard()
{
    fields =  new JTextField[TEXT_FIELD_COUNT];
    setPreferredSize(new Dimension(1,299));
    setBackground(yungMoney);
    JPanel panel = new JPanel(new GridLayout(0,14));
    panel.setBackground(yungMoney);
    for(int t=0; t<4; t++)
    {
        for (int i =0; i < boxes.length; i++)
        {
            boxes[i] = Box.createHorizontalBox();
            for (int j=0; j< TEXT_FIELD_COUNT/SUIT_COUNT; j++)
            {
                int index = i * (TEXT_FIELD_COUNT/SUIT_COUNT) + j;
                fields[index] = new JTextField("    ");
                fields[index].setEditable(false);
                fields[index].setPreferredSize(new Dimension(50, 50));
                fields[index].setBorder(BorderFactory.createLineBorder(Color.BLACK,1));
                panel.add(fields[index]);
            }
        }
    }
    panel.setBorder(BorderFactory.createTitledBorder(BorderFactory.createLineBorder(Color.BLACK,2),"WHEEL OF FORTUNE"));
    add(panel);
}
public static String findPuzzle()
{
    for(int i=0; i<puzzles.length;i++)
    {
        puzzless = puzzles[(int) Math.round(Math.random() * (puzzles.length-1))];
        for(int j=0; j<puzzless.length; j++)
        {
            puzzle = puzzless[(int) Math.round(Math.random() * (puzzless.length-1))];
        }
    }
    return puzzle;
}
public static void reset()
{
    findPuzzle();
    field = new ArrayList<>(puzzle.length());
    for(int k=0;k<puzzle.length();k++)
    {
        field.add(fields[k]);
    }
}
public void actionPerformed(ActionEvent e) 
{
    //game logic
}
} 

所以，JTextField Array是在类 letterBoard 的构造函数内形成的。构造函数正在运行并且按预期工作。然而，String puzzles[][] ，它保存了拼图被归档的各种数组，(这是一个命运之轮游戏。每个人 array 都是一个里面有拼图的类别，等等)并没有按照我想要的方式与我合作。我本质上想要发生的是:方法 reset()获取构造函数中形成的 letterBoard 并用 String 填充它。在方法findPuzzle()中选择。从那里，一个ActionListener在主课中，wheelGUI将连接到JButton reset ，按下时应调用 reset()方法来自letterBoard类并从板上删除当前拼图，并用从 puzzles[][] 中随机选择的新字符串填充它。 ，允许新一轮的游戏。抱歉，如果这有点……令人困惑。我自己也很困惑。我看了一些写作教程Strings到JTextFields ，但我的设置略有不同，并且不允许这种方法起作用。感谢您花时间查看此内容。我将发布wheelGUI类代码(如果需要)，但我认为它不包含与此问题有关的任何相关信息。再次感谢。

我认为你正在尝试做类似的事情......

public static void reset() {
    findPuzzle();
    field = new ArrayList<>(puzzle.length());
    // Clear the existing values
    for (int index = 0; index < fields.length; index++) {
        fields[index].setText(null);
    }
    // Update the new values
    for (int k = 0; k < puzzle.length(); k++) {
        // Get an individual character from the String and make it a String
        // cause it's easier to deal with...
        String character = Character.toString(puzzle.charAt(k));
        fields[k].setText(character);
        field.add(fields[k]);
    }
}

现在这将显示答案，但我认为你可以解决它......
