Build error using Audioplayer class

Question

When trying to compile the code below:

import javax.swing.*;
import sun.audio.*;
import com.sun.java.util.*; 
import java.awt.*;
import java.awt.Event.*;
import java.io.*;

public class filechus {
    public static void main(String[]args) {

        JFrame tela = new JFrame("Telex"); 
        JFileChooser filex = new JFileChooser();

        int opcao = filex.showOpenDialog(tela);

        if (opcao==JFileChooser.APPROVE_OPTION) { 
            File nomearquivo = filex.getSelectedFile();
            try {
                InputStream arq = new FileInputStream(nomearquivo); 
                AudioStream som = new AudioStream(arq); 
                AudioPlayer.player.start(som); 
                System.out.println("Tocando");
            }
            catch(Exception e) {
                System.out.println("Deu erro");
            }
        }
        tela.setBounds(10,10,800,600);
        tela.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        tela.setVisible(true);
    }
}

I get the following error message:

Audioplayer is Internal Proprietary api and may be Removed in a Future release

How can I fix this?

Your problem is with Rts:

import sun.audio.*;
import com.sun.java.util.*;

The packages sun.*, sunw.* and com.sun.* are proprietary and internal JDK packages that should not be used by applications, which is why your compiler complains about them. In my case at least, the package com.sun.java.util doesn’t even exist.

To fix this, I managed by making use of the package classes javax.sound.sampled:

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

public class filechus {
    public static void main(String[]args) {
        JFrame tela = new JFrame("Telex");
        JFileChooser filex = new JFileChooser();
        int opcao = filex.showOpenDialog(tela);
        if (opcao == JFileChooser.APPROVE_OPTION) { 
            File nomearquivo = filex.getSelectedFile();

            try {
                InputStream arq = new BufferedInputStream(new FileInputStream(nomearquivo));
                AudioInputStream som = AudioSystem.getAudioInputStream(arq);
                Clip clip = AudioSystem.getClip();
                clip.open(som);
                clip.start();
                System.out.println("Tocando");
            }
            catch(Exception e) {
                e.printStackTrace();
            }
        }
        tela.setBounds(10,10,800,600);
        tela.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
        tela.setVisible(true);
    }
}

Also note that when handling the error, it is important that the program at least tells you what error it gave to help you fix it.
