经过大量的研究和反复试验，我无法找出如何String从 aString Array中的Arraya中准确地随机选择一个并将其打印出来，在按下 a后String Array逐个字符地打印到 a上。我知道这听起来……很尴尬，我不知道该如何表达才能让它听起来不那么尴尬。所以，这是我制作的课程，它使on a .JTextField ArrayJButtonJTextField ArrayJPanel

因此，JTextField Array是在类的构造函数中形成的letterBoard。构造函数正在运行并按预期工作。但是，String puzzles[][]它包含了将拼图放入的各种数组，（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）并没有像我希望的那样与我一起工作。我本质上想要发生的是：该方法reset()采用在构造函数中形成的 letterBoard 并用String方法中选择的内容填充它findPuzzle()。从那里，ActionListener主类中的anwheelGUI将连接到JButton reset，当按下时，应该reset()从letterBoard上课并从板上擦掉当前的谜题，并用一个新的、随机选择的字符串填充它puzzles[][]，允许新一轮的游戏玩法。对不起，如果这有点......令人困惑。我自己对此感到困惑。我查看了一些写到Strings上的教程JTextFields，但我的设置略有不同，并且不允许这种方法起作用。感谢您花时间看这个。如果需要，我会发布wheelGUI课程代码，但我认为它没有包含与此问题有关的任何相关信息。再次感谢。

我认为您正在尝试做类似...

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 Random 函数随机数并将其作为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];
