내 메인 화면에서 음악 재생

Question

배경 음악으로 응용 프로그램을 제작하고 있습니다. 음악을 재생하기 위해 수업을 작성했으며 실행하면 재생이 시작됩니다. 또한 JFrame보기 클래스를 작성했습니다.

이제 JFrame을 열면 다른 클래스의 음악이 재생되기를 바랍니다.

어떻게하면됩니까? 내보기 클래스

코드 : 내 사운드 클래스

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(); 
    } 

}

소리가 난다. 다음과 같은 내용 :

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(); 
     } 
    }); 
}
