KelasAudio Documentation

Author: ASUS

This class is a simple audio player using Java Swing and the sun.audio package to play and stop audio.

Class: KelasAudio

The KelasAudio class extends javax.swing.JFrame and provides a GUI for playing and stopping an audio file.

Fields

  • private AudioStream audioStream; - Holds the audio stream object.
  • private boolean isPlaying = false; - Indicates whether the audio is currently playing.

Constructor

public KelasAudio() {
    initComponents();
}

The constructor initializes the components of the form.

Methods

private void initComponents()

This method is called from within the constructor to initialize the form. It sets up the GUI components.

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt)

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    if (!isPlaying) {
        try {
            InputStream in = new FileInputStream(new File("C:\\Users\\bagas\\Music\\Taylor Swift - Style (Taylor's Version).wav"));
            audioStream = new AudioStream(in);
            AudioPlayer.player.start(audioStream);
            isPlaying = true;
        } catch (IOException e) {
            System.out.println(e);
        } 
    }
}

This method is called when the play button (jButton1) is pressed. It starts playing the audio if it is not already playing.

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt)

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
    if (isPlaying) {
        AudioPlayer.player.stop(audioStream);
        isPlaying = false;
    }
}

This method is called when the pause button (jButton2) is pressed. It stops the audio if it is currently playing.

Main Method

public static void main(String args[]) {
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new KelasAudio().setVisible(true);
        }
    });
}

The main method launches the application by creating an instance of KelasAudio and making it visible.

GUI Components

The following GUI components are declared and initialized in the initComponents method:

  • jPanel1 - A JPanel that holds the other components.
  • jButton1 - A JButton for playing audio.
  • jButton2 - A JButton for pausing audio.
  • jLabel1 - A JLabel displaying an image.
  • jLabel2 - A JLabel displaying text.
