Emit a beepTag(s): IO


There are three ways to emit a beep in Java.
  • Use an AU audio file
    For Java, AU files need to be created at a sample rate of 8000. Any sample rate beyound that will not work. See also this How-to.

  • Print the ASCII Bell character to the console 
    public class TestBeep {
  public static main(String args[]) {
     // ASCII bell
     System.out.print("\007");
     System.out.flush();
  }
}
    The buzzer on the motherboard is used.
  • Starting with JDK 1.1, use the beep method in the Toolkit 
    import java.awt.*;
public class Beep {
  public static void main(String args[]) {
     Toolkit.getDefaultToolkit().beep();     
  }
}
    (Windows) The sound used is determined from the setting found in Control Panel/Sounds and Devices/Sounds/Sound Scheme/"Default Beep". If no sound file is selected then the beep() will be a silence.
