Java AWT Piano Button Click Sound

Java AWT Piano Button Click Sound :

This code is continuation of this JAVA AWT CHANGE LABEL TEXT BASED ON BUTTON EVENTS.

Copy the codes below and save them in a file called “SimpleAwtGui.java”. Be aware of  the case of the file name as the class name should match file name.

Here I’ve used a relative path (relative against project file path) for my sound file. But it will create problem once the class is packaged. I will fix that in the next post. Here my sound file is located inside src folder where SimpleAwtGui.java is also located.

Java can not play mp3 without external plugins or javafx. It can play wav files but they need to be 8 or 16 bit. There are many free sound websites download wav files from there and paste it in the same folder as your java file. If that doesn’t work then use an absolute path for example, “C:\\sound.wav”. Another way is directly pasting inside intellij idea src folder.

Also all of the buttons play the same sound since I’ve added same music file for all the buttons. They can be modified to play different sound with different button clicks.

Only changes from last version is highlighted below.


Sample:

button events click sound
button events click sound

 

Code:

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.File;
