经过大量研究和反复试验后，我无法找到如何从String String Array Array中的String Array中随机选择JTextField Array并在按下JButton后按字符逐个打印出JTextField Array。我知道这听起来很......尴尬，并不确定如何用它来表达它听起来不那么尴尬。所以，这是我在JPanel上制作package wheelOfFortune;

的课程。
JTextField Array因此，letterBoard是在类String puzzles[][]的构造函数中形成的。构造函数正在运行并按预期工作。然而，array，其中包含谜题所包含的各种阵列，（这是一个财富游戏的轮子。每个人reset()是一个内部有谜题的类别，等等）不能使用我，我希望如何。我基本上想要发生的是：方法String获取构造函数中形成的letterBoard，并使用方法findPuzzle()中选择的ActionListener填充它。从那里开始，主要班级wheelGUI将JButton reset连接到reset()，当按下时，应该从letterBoard调用puzzles[][]方法然后从棋盘上擦除当前拼图，并用Strings中随机选择的新词填充它，允许新一轮的游戏玩法。对不起，如果这有点......令人困惑。我自己也很困惑。我查看了一些将JTextFields写入wheelGUI的教程，但我的设置略有不同，并且不允许这种方法工作。感谢您抽出宝贵时间来看看这个。如果需要，我会发布{{1}}类代码，但我不认为它包含与此问题相关的任何相关信息。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......

使用随机函数随机数并将其用作索引从谜题中获取随机字符串;
Random r = new Random();
int ind1 = r.nextInt(puzzles.length);
int ind2 = r.nextInt(puzzles[0].length);
//process puzzles[ind1][ind2];
