Solved: How to play sounds on java

How to play sounds on In this article, we will dive into playing sounds in Java, a common problem faced by developers when building various applications, such as games and multimedia players. We will discuss a step-by-step solution, explore the libraries needed to accomplish this task, and provide an in-depth explanation of the code. Java, known for its versatility and ease of use, is equipped with diverse libraries that can help developers improve the functionality and capabilities of their applications. One such significant area includes sound and audio support.

Introduction to Java Sound API

The Java Sound API is a powerful toolkit designed to provide sound support across all platforms. It comes bundled with the Java Development Kit (JDK) and enables developers to play, record, and process audio files in various formats. In this article, we will focus on the basics of playing sound in Java applications using the AudioClip and AudioSystem classes, which are part of the Java Sound API.

The Java Sound API can be categorized into two primary packages: javax.sound.sampled and javax.sound.midi. The sampled package is used to handle basic audio functionalities such as playing, recording, and synthesizing audio data, whereas the midi package is designed for managing MIDI-based music compositions and soundtracks.

Playing Sounds using AudioClip

To begin with, let’s explore how to play sound files using the AudioClip interface, which is part of the java.applet package. Although the AudioClip interface was initially created for applets, it is still relevant and useful for playing small audio files in Java applications.

import java.applet.AudioClip;
public class SoundPlayer {
    public static void main(String[] args) {
        AudioClip sound;
        URL soundURL = SoundPlayer.class.getResource("sound.wav");
        sound = java.applet.Applet.newAudioClip(soundURL);;

In the code snippet above, we have imported the AudioClip interface and the URL class. These classes allow us to load an audio resource and play it using the play() method of the AudioClip instance. To use an AudioClip, make sure to put the “sound.wav” file in the same directory as your Java file or provide the correct file path.

However, if you are working with larger audio files or need more sophisticated control over the playback, the AudioClip interface may not be sufficient, and you should consider using the AudioSystem class.

Playing sounds using the AudioSystem class

The AudioSystem class is part of the javax.sound.sampled package and provides more advanced audio playback capabilities. The following example demonstrates how to play an audio file using the AudioSystem class:

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;

public class SoundPlayer {
    public static void main(String[] args) {
        try {
            File soundFile = new File("sound.wav");
            AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(soundFile);
            Clip clip = AudioSystem.getClip();

            // Keep the application running till the sound is played completely
            Thread.sleep(clip.getMicrosecondLength() / 1000);
        } catch(LineUnavailableException | UnsupportedAudioFileException | IOException | InterruptedException e) {

In this example, we first imported the required classes and interfaces from the javax.sound.sampled package. Then, we created an AudioInputStream object to read the audio data from the file, and a Clip instance to hold the audio data in memory. After opening the clip, we called the start() method to play the sound.

This approach provides more control over the audio playback, including the ability to pause, resume, loop, and stop the sound, making it suitable for a wide range of applications.

To sum up, we discussed two different approaches to playing sounds in Java using the AudioClip and AudioSystem classes. The AudioClip interface is suitable for small audio files in simple applications, while the AudioSystem class offers advanced audio playback capabilities for more complex scenarios. Leveraging Java’s powerful libraries ensures seamless sound functionality and an enhanced user experience across various applications.
