这段代码只是定义了一个 Dialog 类，它包含了对话框的基本属性和方法，但并没有实现对话框的显示和交互逻辑。你需要在这个类的 show() 方法中添加对话框的显示逻辑，可以使用 Java 的 GUI 库（如 Swing 或 JavaFX）来创建对话框的 UI，并在 submit、cancel、close 按钮的点击事件中添加对应的交互逻辑。具体实现方式可以参考 Java GUI 相关的教程和示例代码。

java利用awt和swing实现通讯录管理系统

要实现通讯录管理系统，可以使用 Java 的 AWT（Abstract Window Toolkit）和 Swing 库来设计用户界面。以下是一个简单的示例：

1. 首先，创建一个 JFrame 窗口，设置其大小和布局：

import javax.swing.*;
import java.awt.*;

public class AddressBook extends JFrame {
    public AddressBook() {
        setTitle("Address Book");
        setSize(500, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());
    }
}

2. 在 JFrame 窗口中添加一个 JPanel，用于放置通讯录条目。使用 JScrollPane 包装 JPanel，以便在需要时可以滚动：

import javax.swing.*;
import java.awt.*;

public class AddressBook extends JFrame {
    public AddressBook() {
        setTitle("Address Book");
        setSize(500, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        JPanel contentPane = new JPanel();
        contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.PAGE_AXIS));

        JScrollPane scrollPane = new JScrollPane(contentPane);
        add(scrollPane, BorderLayout.CENTER);
    }
}

3. 创建一个通讯录条目的类 AddressEntry，包括姓名、电话和电子邮件等信息：

public class AddressEntry {
    private String name;
    private String phoneNumber;
    private String email;

    public AddressEntry(String name, String phoneNumber, String email) {
        this.name = name;
        this.phoneNumber = phoneNumber;
        this.email = email;
    }

    public String getName() {
        return name;
    }

    public String getPhoneNumber() {
        return phoneNumber;
    }

    public String getEmail() {
        return email;
    }
}

4. 在 JPanel 中添加一个按钮，用于添加新的通讯录条目。创建一个对话框，让用户输入新条目的信息：

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class AddressBook extends JFrame {
    private JPanel contentPane;

    public AddressBook() {
        setTitle("Address Book");
        setSize(500, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new BorderLayout());

        contentPane = new JPanel();
        contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.PAGE_AXIS));

        JScrollPane scrollPane = new JScrollPane(contentPane);
        add(scrollPane, BorderLayout.CENTER);

        JButton addButton = new JButton("Add");
        addButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // Create a dialog to get the new entry information
                JPanel panel = new JPanel();
                panel.setLayout(new GridLayout(3, 2));
                JTextField nameField = new JTextField();
                JTextField phoneField = new JTextField();
                JTextField emailField = new JTextField();
                panel.add(new JLabel("Name:"));
                panel.add(nameField);
                panel.add(new JLabel("Phone:"));
                panel.add(phoneField);
                panel.add(new JLabel("Email:"));
                panel.add(emailField);
                int result = JOptionPane.showConfirmDialog(null, panel, "Add New Entry", JOptionPane.OK_CANCEL_OPTION);
                if (result == JOptionPane.OK_OPTION) {
                    // Add the new entry to the content pane
                    AddressEntry entry = new AddressEntry(nameField.getText(), phoneField.getText(), emailField.getText());
                    addEntry(entry);
                }
            }
        });
        add(addButton, BorderLayout.SOUTH);
    }

    private void addEntry(AddressEntry entry) {
        JLabel label = new JLabel(entry.getName() + " " + entry.getPhoneNumber() + " " + entry.getEmail());
        contentPane.add(label);
        contentPane.revalidate();
        contentPane.repaint();
    }
}

5. 启动应用程序，显示通讯录管理系统窗口：

public class Main {
    public static void main(String[] args) {
        AddressBook addressBook = new AddressBook();
        addressBook.setVisible(true);
    }
}

这是一个基本的通讯录管理系统，可以通过添加新的通讯录条目来扩展功能。当然，这只是一个简单的示例，真正的通讯录管理系统可能需要更复杂的功能和更多的界面元素。

只用awt不用Swing写以下代码package chap03; import javax.swing.; import java.awt.; import java.awt.event.*; public class GuessNumber extends JFrame implements ActionListener { private JLabel promptLabel, resultLabel; private JTextField inputField; private JButton guessButton, exitButton; private int targetNumber, guessCount, maxTryTime; public GuessNumber () { targetNumber = (int)(Math.random()*10)+1; guessCount = 0; maxTryTime = 5; promptLabel = new JLabel("请输入一个0~10之间的数字："); inputField = new JTextField(10); guessButton = new JButton("猜！"); guessButton.addActionListener(this); exitButton = new JButton("退出"); exitButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.exit(0); } }); resultLabel = new JLabel(""); JPanel panel = new JPanel(); panel.add(promptLabel); panel.add(inputField); panel.add(guessButton); panel.add(exitButton); panel.add(resultLabel); this.add(panel); this.setTitle("猜数字游戏界面"); this.setSize(300, 150); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } public void actionPerformed(ActionEvent e) { String inputText = inputField.getText(); try { int guessNumber = Integer.parseInt(inputText); guessCount++; if (guessCount < maxTryTime) { int c = maxTryTime - guessCount; if (guessNumber > targetNumber) { resultLabel.setText("输入的过大，您还有" + c + "次机会"); } else if (guessNumber < targetNumber) { resultLabel.setText("输入的过小，您还有" + c + "次机会"); } else { resultLabel.setText("恭喜你，猜对了！你一共猜了" + guessCount + "次"); guessButton.setEnabled(false); } } else { resultLabel.setText("抱歉游戏失败"); guessButton.setEnabled(false); } } catch (NumberFormatException ex) { resultLabel.setText("输入异常，请重新输入!!!"); } } public static void main(String[] args) { new GuessNumber(); } }运行时能给文字足够的显示空间

以下是只用 AWT 不用 Swing 写 GuessNumber 类的代码，增加了一些布局和字体设置，以保证文字有足够的显示空间：

package chap03;

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

public class GuessNumber extends Frame implements ActionListener {
    private Label promptLabel, resultLabel;
    private TextField inputField;
    private Button guessButton, exitButton;
    private int targetNumber, guessCount, maxTryTime;

    public GuessNumber () {
        targetNumber = (int)(Math.random()*10)+1;
        guessCount = 0;
        maxTryTime = 5;

        promptLabel = new Label("请输入一个0~10之间的数字：");
        promptLabel.setFont(new Font("Dialog", Font.PLAIN, 14));

        inputField = new TextField(10);
        inputField.setFont(new Font("Dialog", Font.PLAIN, 14));

        guessButton = new Button("猜！");
        guessButton.addActionListener(this);
        guessButton.setFont(new Font("Dialog", Font.PLAIN, 14));

        exitButton = new Button("退出");
        exitButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        exitButton.setFont(new Font("Dialog", Font.PLAIN, 14));

        resultLabel = new Label("");
        resultLabel.setFont(new Font("Dialog", Font.PLAIN, 14));

        Panel panel = new Panel(new FlowLayout(FlowLayout.CENTER, 10, 10));
        panel.add(promptLabel);
        panel.add(inputField);
        panel.add(guessButton);
        panel.add(exitButton);

        setLayout(new BorderLayout(10, 10));
        add(panel, BorderLayout.CENTER);
        add(resultLabel, BorderLayout.SOUTH);

        setTitle("猜数字游戏界面");
        setSize(300, 150);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        String inputText = inputField.getText();
        try {
            int guessNumber = Integer.parseInt(inputText);
            guessCount++;
            if (guessCount < maxTryTime) {
                int c = maxTryTime - guessCount;
                if (guessNumber > targetNumber) {
                    resultLabel.setText("输入的过大，您还有" + c + "次机会");
                } else if (guessNumber < targetNumber) {
                    resultLabel.setText("输入的过小，您还有" + c + "次机会");
                } else {
                    resultLabel.setText("恭喜你，猜对了！你一共猜了" + guessCount + "次");
                    guessButton.setEnabled(false);
                }
            } else {
                resultLabel.setText("抱歉游戏失败");
                guessButton.setEnabled(false);
            }
        } catch (NumberFormatException ex) {
            resultLabel.setText("输入异常，请重新输入!!!");
        }
    }

    public static void main(String[] args) {
        new GuessNumber();
    }
}
