java - 如何根据"is"或“否”按钮/选项 Pane 组合或调用另一个类

Question

我有两个单独的类(class)。一个是神奇的8号球，另一个是播放星际歌曲的Wav播放器。

import java.security.SecureRandom;
import javax.swing.JOptionPane;
import javax.swing.ImageIcon;



public class Magic8Ball {

private final static ImageIcon image = new ImageIcon("images/BuckminsterFuller.jpg");
private final static SecureRandom rand = new SecureRandom();
private final static String wisdom[] = {
        "Not Synergistically feasible",
        "It is geometrically analytical",
        "Your question does not follow General Semantics, hazy, try again",
        "Yes - Sustainable",
        "No, energetically inefficient",
        "Maybe a Dymaxion process.  Technology not up to date.",
        "Your question is negatively Entropic.",
        "Everyone is born a genius, but the process of living de-geniuses them.",
        "Humanity is acquiring all the right technology for all the wrong reasons.",
        "We are called to be architects of the future, not its victims",};


public static void main(String[] args) {

    boolean askQ = true;

    while (askQ) {
        String question = getUserQ();
        String randomWisdom = getRandomWisdom();

        showWisdom(question, randomWisdom);

        askQ = userWantsToAskAnotherQ();
    }


}

private static String getUserQ() {
    return JOptionPane.showInputDialog(null,
            "Ask a question that has to do with the structural integrity of earth:",
            "Only Engineers, Scientists and Architects allowed",
            JOptionPane.INFORMATION_MESSAGE);
}

private static String getRandomWisdom() {
    return wisdom[rand.nextInt(wisdom.length)];
}

private static void showWisdom(String question, String randomWisdom) {
    JOptionPane.showMessageDialog(null, question + "\n" + randomWisdom, 
            "Buckminster's Magic-8 Ball has responded.", 
            JOptionPane.PLAIN_MESSAGE, image);
}

private static boolean userWantsToAskAnotherQ() {
    return 0 == JOptionPane.showConfirmDialog(null, "Abort Mission or Dock "
            + "while Hearing" + "\n" + "No Time for Caution? by Hans Zimmer", 
            "Would you like to stay on spaceship earth or abandon ship?", 
            JOptionPane.YES_NO_OPTION, 0, image);
}

}

因此，正如您在类(class)结束时所看到的，当听到 Hans Zimmer 没有时间谨慎时，选项是中止任务或停靠。因此，如果用户点击"is"，我怎样才能激活它或调用我为星际歌曲提供的这个类:

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;
import javax.swing.*;
import java.io.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.logging.Level;
import java.util.logging.Logger;

public class WavPlayer extends JFrame { 
JButton btn = new JButton("Play No Time For Caution");
File wavFile;
URL defaultSound;
public static Clip clip;
public static AudioInputStream audioInputStream;

public WavPlayer(String url) {
    try {
        setSize(300, 100);
        setLocation(400, 300);
        setDefaultCloseOperation(EXIT_ON_CLOSE);
        JPanel jp = new JPanel();
        defaultSound = new URL (url);

        jp.add(btn);

        getContentPane().add(jp);
        pack();

        btn.addActionListener(new ActionListener() {             
            @Override
            public void actionPerformed(ActionEvent e) {
                play();
            }
        });
    } catch (MalformedURLException ex) {
        Logger.getLogger(WavPlayer.class.getName()).log(Level.SEVERE, null, ex);
    }
}

public void play() {
    try {
        audioInputStream = AudioSystem.getAudioInputStream(defaultSound);

        try {
            clip = AudioSystem.getClip();
            clip.open(audioInputStream);
            clip.loop(20000);
            clip.start();

        } catch (LineUnavailableException e) {
        }

    } catch (UnsupportedAudioFileException | IOException e) {
    }
}

public void stop() {
    clip.stop();
}

public static void main(String args[]) {
    WavPlayer t = new WavPlayer("file:C:/Users/borjax01/Desktop/Netbeans/JavaApplication/music/Interstellar.wav");
    t.setVisible(true);

}
}

编辑:我已经通过重构并将一个类移动到另一个类中来组合这两个类。我想要做的是，我希望 8ball 类在 8ball 类结束时调用 WavPlayer 类，当提示用户再次玩时，他们点击"is"来激活 wavplayer 类.... .

Answer 1

你遇到了什么错误？也许“内部类不能有静态声明”？

您可以尝试另一种方法。不要嵌套 wav 播放器类，而是在 Magic8Ball 类后面插入 if。这两个类可以存在于同一个文件中，但如您所知，只有其中一个类可能是公共(public)的。
