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.

Java AWT Change Label Text based on Button Events

Java AWT Change Label Text based on Button Events :

This code is continuation of this Java Frame Change Button Colors Based on Even Odd Logic.

Quite a bit has changed since last version. I have put some codes into functions to make them organize. I will not separate the code into multiple files though to keep it simple. 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. Change in this code from last version is ActionListener interface is implemented to handle button events. It has only one method ActionPerformed which is used to deal different actions. Here i change label based on which button was clicked.

Here I’ve used setActionCommand to identify which key was pressed based on my assigned command.


Sample:

button events change label 1
button events change label 1
button events change label 2
button events change label 2

Java AWT Adding Panels to Frame

Java AWT Adding Panels to Frame:

This code is continuation of this tutorial to add MenuItem to Menu. Changes that need to be made from the last code is highlighted below.

Here, GridLayout(2,1) create 2 rows and 1 column in the frame. It is very useful for creating custom designs.

This code is continuation of this tutorial Java AWT Creating Piano Buttons with Grid Layout.

First of all none of the buttons will work because i haven’t added any event listeners and handlers. Also menu items are not added yet.
