Best way to get Sound on Button Press for a Java Calculator?

Æthereal Programmer picture Æthereal Programmer · Mar 20, 2013 · Viewed 30.4k times · Source

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.

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;
