I'm a learning Java student working on an independent project for my Resume. I decided to do a Java calculator because I know most of the components that make it up. One thing I don't know how to do is add sound on the button press. I have a vague idea what with the Audiostream input stuff. But I need unique sounds for each button on my calculator. Right now my calculator isn't completely finished (listeners don't work yet.) I was just wondering what would be the best way to incorporate my .wav files into the button presses. Thanks in advance.

Following steps are to be followed to play a clip object. getAudioInputStream(File file). AudioInputStream converts an audio file into stream. Get a clip reference object from AudioSystem. Stream an audio input stream from which audio data will be read into the clip by using open() method of Clip interface.
String soundName = "yourSound.wav";
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(new File(soundName).getAbsoluteFile());
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.start();
This should help you in achieving what you want.
And yeah, you will require these imports:-
import java.io.File;
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
public static synchronized void playSound(final String url) {
new Thread(new Runnable() { // the wrapper thread is unnecessary, unless it blocks on the Clip finishing, see comments
public void run() {
try {
Clip clip = AudioSystem.getClip();
AudioInputStream inputStream = AudioSystem.getAudioInputStream(Main.class.getResourceAsStream("/path/to/sounds/" + url));
clip.open(inputStream);
clip.start();
} catch (Exception e) {
System.err.println(e.getMessage());
}
}
}).start();
}
