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;

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.

You're missing a space.

I'm creating an application which I have to send multiple images one after another and I use Object(Output/Input)Stream inside of a while loop. But It only send one file I guess its the first image. Can I send multiple files with Object(Output/Input)Stream? If so, What's the issue with my code?

That endless loop is not so endless -- in fact, it will not even loop once.
You have a "return null" at the end of your "while(true)" block. After the first iteration, your method will return.

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.
I am attempting to add an audio player to my application. Here's the code from the class that handles audio playing:

public class AudioPlayer {
private AudioPlayer() { }
private static AudioPlayer instance = new AudioPlayer();
public static AudioPlayer getInstance() {
return instance;
}
private static ArrayList<BigClip> clips = new ArrayList<BigClip>();
private BigClip get(String name) {
for (BigClip clip : clips) {
if (clip.getName().equalsIgnoreCase(name)) return clip;
}
return null;
}
public void play(File file) {
try {
AudioInputStream audioIn = AudioSystem.getAudioInputStream(file);
BigClip clip = get(file.getName());
if (clip == null) {
BigClip newClip = new BigClip(file.getName());
clips.add(newClip);
clip = newClip;
}
clip.open(audioIn);
clip.start();
}
catch (Exception e) { e.printStackTrace(); }
}
}
However, when I try to run it using:
AudioPlayer.getInstance().play(new File("audio/people/blacksmith/blacksmith01a_new.wav"));
I get the following stack trace:
javax.sound.sampled.UnsupportedAudioFileException: could not get audio input stream from input file

Here's the format I used when exporting the file with Audition.
Nevermind, I fixed it by using this library: http://www.javazoom.net/javalayer/javalayer.html
