How to import sun.audio?

I am attempting to play audio for a program and I need the AudioStream class and the AudioPlayer class, but when I attempt to import them Eclipse gives me an error.
Method where used:
public static void playMusic(String filepath) {
InputStream music;
try {
music = new FileInputStream(new File(filepath));
AudioStream audio = new AudioStream(music);
AudioPlayer.player.start(audio);
} catch(Exception e) {
JOptionPane.showMessageDialog(null, "Error");
}
}
Imports:
import java.io.File;
import java.io.FileInputStream;
import java.io.InputStream;
import javax.swing.JOptionPane;
import sun.audio.AudioPlayer;
import sun.audio.AudioStream;

Variable Not Changing in If Statement with Sarxos Motion Detection

I'm trying to have my program print a few "funny" images whenever it detects motion. Everything works by itself but when I put the if(detection == true) statement into the program, the variable doesn't update. How could I get it to update inside of the motionDetected function?
I've tried using boolean and int for the variable but I think it could be with the way I've structured it.

Why does this not work? It gives me a NullPointerException?

I found out why it wasn't working! I had put "/" before 'res/music.wav' which caused the file loading system to think I was loading from a DRIVE (eg C:/ F:/), but there was nothing before that / so it thought it was loading from a null drive, which cannot exist.

How to loop a sound while button is pressed and stop when released?

I've tried to search similiar question to this, but couldn't find. I don't know how i can stop my sound when button is released, and also, i don't know how to loop sound only one by one, when i hold button it plays again while previous loop is still playing, and the sound is becoming a loop from ∞ sounds.

Anyone can help me with this issue?

I don't know how i can stop my sound when button is released?
You can stop the the clip by using DataLine#stop(). Just keep the reference of last played clip and call below line to stop it.
clip.stop();
Note: You can store it somewhere in static variable.
Sample code:
private static Clip clip;
...
public void keyReleased(KeyEvent e) {
if (clip != null) {
clip.stop();
}
}
...
public void playSound(File soundName) {
...
clip = AudioSystem.getClip();
...
}

When I hold the Button it plays again while previous loop is still playing.
This is because for every keyPress you are creating a new File object. That should be avoided.
To stop sound:
I would add a boolean parameter to playsound method. And depending upon the parameter passed I would call clip.start() or clip.stop() (superclass DataLine has a stop method) .
Call playsound(filename,false); in keyReleased.
public void playSound(File soundName , boolean start)
{
try
{
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundName.getAbsoluteFile( ));
Clip clip = AudioSystem.getClip( );
clip.open(audioInputStream);
if(start == true)
clip.start();
else
clip.stop();
}
catch(Exception ex)
{
System.out.println("Error with playing sound.");
ex.printStackTrace( );
}
}

AudioInputStream is not working

I'm trying to play a .wav sound every time the user presses a button, but an exception gets thrown:
Exception in thread "Thread-0" java.lang.IllegalArgumentException: Invalid format

Here's the code:
//Play Audio File
public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
{
AudioInputStream inputStream = AudioSystem.getAudioInputStream(new File(file));
Clip clip = AudioSystem.getClip();
clip.open(inputStream);
clip.start();
}

I managed to get it working.
This is the code that I used. Keep in mind that I needed this just to play a short beep.wav sound. It seems to have some trouble with longer sound files. Let me know if it works for you guys and if you manage to play longer sounds with this code.
public void play(String file) throws LineUnavailableException, UnsupportedAudioFileException, IOException
{
try
{
AudioInputStream inputStream = AudioSystem.getAudioInputStream(this.getClass().getResource(file));
AudioFormat format = inputStream.getFormat();
DataLine.Info info = new DataLine.Info(Clip.class, format);
Clip clip = (Clip)AudioSystem.getLine(info);
clip.open(inputStream);
clip.start();
}
catch (IOException | LineUnavailableException | UnsupportedAudioFileException e1)
{
e1.printStackTrace();
}
}

It's something wrong with the file path you are passing. When I use your same code getting the file from a JFileChooser it works fine. Test this out.
