Java 简单的FlowLayOut帮助

我对这个程序有几个问题，我要做的第一件事就是让它可以比较，看看textfield是否等于colorValues[x]位置。第二个问题是if语句表示if inText==to colorValues.length-1，以打开一个表示Congreadurations的框，该框也不起作用。第三个问题，即使收到“抱歉”消息和/或“祝贺”消息，您如何使其不显示文本字段

首先，我建议您学习正确地格式化代码，因为这样可以更容易地看到正在发生的事情

其次，您发布的代码在第64行和第80行出现语法错误，导致编译失败。问题是Java不允许在源代码中包含多行字符串文字，因此必须将这两个字符串连接在一起。例如：

darn.namePrompt.setText("Congradulations,
   Your mind is Awesome!!!");

应该是：

darn.namePrompt.setText("Congradulations," + 
    " Your mind is Awesome!!!");

现在，不幸的是，您的问题没有特别清楚地说明程序的预期行为应该是什么。我对它的理解是，您希望向用户提供一个文本框，要求他们输入第一种颜色，然后显示一个对话框，根据他们得到的答案是否正确表示祝贺或抱歉。如果他们得到正确的答案，那么您需要显示第二种颜色的输入框，检查答案，等等

我的第一个建议是在实例化JFrame时创建所有控件，但只需隐藏其他控件，直到用户输入正确的值。接下来，我建议您在开始编写代码之前计划动作侦听器将要做什么

在这种情况下，程序需要存储用户当前正在处理的输入字段的数组索引。然后，侦听器需要检查此变量，并验证inputFields数组中的相应字段。侦听器需要向用户显示一个对话框，说明他们是否得到了正确答案，如果用户得到了正确答案，则启用下一个输入字段

把所有这些放在一起，你会得到：

import javax.swing.*;

import java.awt.*;
import java.awt.event.*;

public class AlbertCardonaProg7 extends JFrame {
    private static final int WIDTH = 350;
    private static final int HEIGHT = 250;
    private static final String[] colorValues = { "red", "white", "yellow",
        "green", "blue" };

    private final JLabel[] inputLabels = new JLabel[colorValues.length];
    private final JTextField[] inputFields = new JTextField[colorValues.length];
    private int index = 0;

    public AlbertCardonaProg7() {
        //Create the UI controls
        for (int i = 0; i < colorValues.length; i++) {
            inputLabels[i] = new JLabel("Input color number " + i + ":");
            inputLabels[i].setVisible(false);
            inputFields[i] = new JTextField(15);
            inputFields[i].setVisible(false);
            inputFields[i].addActionListener(new Listener());

            add(inputLabels[i]);
            add(inputFields[i]);
        }

        //Make the first set visible
        inputLabels[0].setVisible(true);
        inputFields[0].setVisible(true);

        setTitle("MEMORY GAME");
        setSize(WIDTH, HEIGHT);
        setLayout(new FlowLayout(FlowLayout.CENTER));
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
    }

    private class Listener implements ActionListener {
        public void actionPerformed(ActionEvent e) {

            if (inputFields[index].getText().equals(colorValues[index])) {
                JOptionPane.showMessageDialog(null, "Congratulations, you got the answer correct");

                //See if there are more controls to make visible
                if (++index < colorValues.length) {
                    inputLabels[index].setVisible(true);
                    inputFields[index].setVisible(true);
                }
            } else {
                JOptionPane.showMessageDialog(null,
                        "Sorry, your answer is wrong", "Error",
                        JOptionPane.ERROR_MESSAGE);
            }
        }
    }

    public static void main(String[] args) {
        String colors = "";
        for (int i = 0; i < colorValues.length; i++) {
            colors += colorValues[i] + "  ";
        }

        JOptionPane.showMessageDialog(null, "How good is your memory.\n"
                + "See if you can memorize this sequence.\n\n" + colors,
                "Message", JOptionPane.INFORMATION_MESSAGE);

        AlbertCardonaProg7 outBox = new AlbertCardonaProg7();

    }
}

编辑：根据您下面的评论，我已修改程序以满足预期行为。主要的变化是构造函数不再隐藏其他控件，监听器现在必须在每个输入字段上循环以检查它们是否正确：

import javax.swing.*;

import java.awt.*;
import java.awt.event.*;

public class AlbertCardonaProg7 extends JFrame {
    private static final int WIDTH = 350;
    private static final int HEIGHT = 250;
    private static final String[] colorValues = { "red", "white", "yellow",
        "green", "blue" };

    private final JLabel[] inputLabels = new JLabel[colorValues.length];
    private final JTextField[] inputFields = new JTextField[colorValues.length];

    public AlbertCardonaProg7() {
        //Create the UI controls
        for (int i = 0; i < colorValues.length; i++) {
            inputLabels[i] = new JLabel("Input color number " + i + ":");
            inputFields[i] = new JTextField(15);
            inputFields[i].addActionListener(new Listener());

            add(inputLabels[i]);
            add(inputFields[i]);
        }

        setTitle("MEMORY GAME");
        setSize(WIDTH, HEIGHT);
        setLayout(new FlowLayout(FlowLayout.CENTER));
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setVisible(true);
    }

    private class Listener implements ActionListener {
        public void actionPerformed(ActionEvent e) {

            // See if there are any wrong answers
            boolean correct = true;
            for(int i = 0; i < colorValues.length; i++) {
                if (!inputFields[i].getText().equals(colorValues[i])) {
                    correct = false;
                }
            }

            if(correct) {
                JOptionPane.showMessageDialog(null, 
                        "Congratulations, you got the answer correct");
            } else {
                JOptionPane.showMessageDialog(null,
                        "Sorry, your answer is wrong", "Error",
                        JOptionPane.ERROR_MESSAGE);

            }
        }
    }

    public static void main(String[] args) {
        String colors = "";
        for (int i = 0; i < colorValues.length; i++) {
            colors += colorValues[i] + "  ";
        }

        JOptionPane.showMessageDialog(null, "How good is your memory.\n"
                + "See if you can memorize this sequence.\n\n" + colors,
                "Message", JOptionPane.INFORMATION_MESSAGE);

        AlbertCardonaProg7 outBox = new AlbertCardonaProg7();

    }
}

我必须编辑它，这样每个人都可以看到所有的代码，并可能给我一些建议，我应该做的步骤。有人可以帮助我与我的循环吗？非常感谢，我确实了解连接，我只是这样做，因为它没有正确地显示在我的计算机上与这个网站，我有它在一行。再次感谢你的回答，我真的很感激。这就是我想要的，我希望他们记住所有的颜色，然后如果他们都正确的话，就说，你是对的，干得好！如果说错了，你错过了，但这真是太棒了。啊，我明白了。您应该能够看到需要更改的内容，尽管我将使用符合您需要的代码进行编辑。
