I want to play, pause and stop songs using an android app in my java server

server Could you guys please help me how do i stop or even pause songs in

My server code goes like this

this.filename = filename;
}
public static void main(String[] args) throws Exception
{
try
{
serverSocket = new ServerSocket(PORT, 0,
InetAddress.getLocalHost());
System.out.println("IP: " + serverSocket.getInetAddress() + "
Port: " + serverSocket.getLocalPort());
} catch (IOException e)
{
System.out.println("Could not listen on port: 7777");
}
System.out.println("Server started. Listening to the port 7777");
while (true)
{
try
{
clientSocket = serverSocket.accept(); // Code para sa
client connection
inputStreamReader = new
InputStreamReader(clientSocket.getInputStream());
bufferedReader = new BufferedReader(inputStreamReader); //
irread ng inputstream yung message na sinend
message = bufferedReader.readLine();
System.out.println(message);{
if(message.equals("play1")){
AudioInputStream inputStream =
AudioSystem.getAudioInputStream(new
File("D:/Kym/From BB/kayMani.wav"));
Clip clip1 = AudioSystem.getClip();
// getAudioInputStream() accepts a File or
InputStream
clip1.open(inputStream);
clip1.start();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null,
"Classical song is playing!");
}
});
}
if(message.equals("play2")) {
AudioInputStream inputStream =
AudioSystem.getAudioInputStream(new
File("D:/Kym/From BB/kayMani.wav"));
Clip clip2 = AudioSystem.getClip();
// getAudioInputStream() accepts a File or
InputStream
clip2.open(inputStream);
clip2.start();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null,
"Novelty song is playing!");
}
});
}
if(message.equals("play3")) {
AudioInputStream inputStream =
AudioSystem.getAudioInputStream(new File("D:/Kym/From
BB/kayMani.wav"));
Clip clip2 = AudioSystem.getClip();
// getAudioInputStream() accepts a File or
InputStream
clip2.open(inputStream);
clip2.start();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null, "OPM
song is playing!");
}
});
}
if(message.equals("play4")) {
AudioInputStream inputStream =
AudioSystem.getAudioInputStream(new File("D:/Kym/From
BB/kayMani.wav"));
Clip clip2 = AudioSystem.getClip();
// getAudioInputStream() accepts a File or
InputStream
clip2.open(inputStream);
clip2.start();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null, "Pop
song is playing!");
}
});
}
if(message.equals("play5")) {
AudioInputStream inputStream =
AudioSystem.getAudioInputStream(new File("D:/Kym/From
BB/kayMani.wav"));
Clip clip2 = AudioSystem.getClip();
// getAudioInputStream() accepts a File or
InputStream
clip2.open(inputStream);
clip2.start();
SwingUtilities.invokeLater(new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null, "Rock
song is playing!");
}
});
}
}
inputStreamReader.close();
clientSocket.close();
} catch (IOException ex)
{
System.out.println("Problem in message reading");
}
}
}
}
