Воспроизведение музыки на главном экране

Question

Я создаю приложение с фоновой музыкой. Я написал класс для воспроизведения музыки, и когда я запустил его, он начнет играть. Я также написал класс представления JFrame.

Теперь я хочу, чтобы при открытии моего JFrame будет воспроизводиться музыка из другого класса.

Как я могу это сделать?

Код с моей точки зрения класса:

package View; 

import java.awt.BorderLayout; 
import java.awt.Color; 
import java.awt.Container; 
import java.awt.Dimension; 
import java.awt.Toolkit; 
import java.io.File; 


import javax.swing.Icon; 
import javax.swing.ImageIcon; 
import javax.swing.JButton; 
import javax.swing.JFrame; 
import javax.swing.JLabel; 

import javax.swing.JPanel; 

import music.PlaySound; 

public class Home extends JFrame { 

    private JLabel label, label1, label2; 
    private JPanel panel; 
    private JButton logo; 
    private Container window = getContentPane(); 

    public Home(){ 
     initGUI(); 
    } 

    public void initGUI(){ 
     setLayout(null); 
     setTitle("Ismail"); 
     setPreferredSize(new Dimension(800,600)); 
     setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 

     label = new JLabel("AFCA");  
     label.setBounds(0, 0, 266, 800); 
     label.setBackground(Color.WHITE); 
     label.setOpaque(true); 
     window.add(label); 

     label1 = new JLabel("AFCA1"); 
     label1.setBounds(267, 0, 266, 800); 
     label1.setBackground(Color.RED); 
     label1.setOpaque(true); 
     window.add(label1); 

     label2 = new JLabel("AFCA2"); 
     label2.setBounds(533, 0, 266, 800); 
     label2.setBackground(Color.WHITE); 
     label2.setOpaque(true); 
     window.add(label2); 

     logo = new JButton(new ImageIcon("../Ajax/src/img/logotje.gif")); 
     logo.setBorderPainted(false); 
     logo.setBounds(40, 100, 188, 188); 
     label1.add(logo); 

     pack(); 
    } 

} 

код из моего звука класса:

package music; 

import java.io.*; 
import javax.sound.sampled.*; 

public class PlaySound 
{ 
    public static void main(String[] args) 
    { 
     sound = new File("../Ajax/src/sound/Sound.wav"); // Write you own file location here and be aware that it needs to be an .wav file 

     new Thread(play).start(); 
    } 

    static File sound; 
    static boolean muted = false; // This should explain itself 
    static float volume = 100.0f; // This is the volume that goes from 0 to 100 
    static float pan = 0.0f; // The balance between the speakers 0 is both sides and it goes from -1 to 1 

    static double seconds = 0.0d; // The amount of seconds to wait before the sound starts playing 

    static boolean looped_forever = false; // It will keep looping forever if this is true 

    static int loop_times = 0; // Set the amount of extra times you want the sound to loop (you don't need to have looped_forever set to true) 
    static int loops_done = 0; // When the program is running this is counting the times the sound has looped so it knows when to stop 

    final static Runnable play = new Runnable() // This Thread/Runnabe is for playing the sound 
    { 
     public void run() 
     { 
      try 
      { 
       // Check if the audio file is a .wav file 
       if (sound.getName().toLowerCase().contains(".wav")) 
       { 
        AudioInputStream stream = AudioSystem.getAudioInputStream(sound); 

        AudioFormat format = stream.getFormat(); 

        if (format.getEncoding() != AudioFormat.Encoding.PCM_SIGNED) 
        { 
         format = new AudioFormat(AudioFormat.Encoding.PCM_SIGNED, 
           format.getSampleRate(), 
           format.getSampleSizeInBits() * 2, 
           format.getChannels(), 
           format.getFrameSize() * 2, 
           format.getFrameRate(), 
           true); 

         stream = AudioSystem.getAudioInputStream(format, stream); 
        } 

        SourceDataLine.Info info = new DataLine.Info(
          SourceDataLine.class, 
          stream.getFormat(), 
          (int) (stream.getFrameLength() * format.getFrameSize())); 

        SourceDataLine line = (SourceDataLine) AudioSystem.getLine(info); 
        line.open(stream.getFormat()); 
        line.start(); 

        // Set Volume 
        FloatControl volume_control = (FloatControl) line.getControl(FloatControl.Type.MASTER_GAIN); 
        volume_control.setValue((float) (Math.log(volume/100.0f)/Math.log(10.0f) * 20.0f)); 

        // Mute 
        BooleanControl mute_control = (BooleanControl) line.getControl(BooleanControl.Type.MUTE); 
        mute_control.setValue(muted); 

        FloatControl pan_control = (FloatControl) line.getControl(FloatControl.Type.PAN); 
        pan_control.setValue(pan); 

        long last_update = System.currentTimeMillis(); 
        double since_last_update = (System.currentTimeMillis() - last_update)/1000.0d; 

        // Wait the amount of seconds set before continuing 
        while (since_last_update < seconds) 
        { 
         since_last_update = (System.currentTimeMillis() - last_update)/1000.0d; 
        } 

        System.out.println("Playing!"); 

        int num_read = 0; 
        byte[] buf = new byte[line.getBufferSize()]; 

        while ((num_read = stream.read(buf, 0, buf.length)) >= 0) 
        { 
         int offset = 0; 

         while (offset < num_read) 
         { 
          offset += line.write(buf, offset, num_read - offset); 
         } 
        } 

        line.drain(); 
        line.stop(); 

        if (looped_forever)

Похоже, вам необходимо добавить к вашему WindowListener JFrame. Что-то вроде этого:

public Home() { 
    initGUI(); 
    this.addWindowListener(new WindowAdapter() { 
     @Override 
     public void windowOpened(WindowEvent e) { 
      PlaySound.sound = new File("../Ajax/src/sound/Sound.wav"); 
      soundThread = new Thread(PlaySound.play).start(); 
     } 
     //If you want the sound to stop you can just add another override, but you need to keep track of the sound thread 
     @Override 
     public void windowClosing(WindowEvent e) { 
      soundThread.interrupt(); 
     } 
    }); 
}
