Emitting a Beep in Java

There are three ways to emit a beep in Java:

Use an AU audio file: In Java, AU files need to be created at a sample rate of 8000. Higher sample rates will not work.

Print the ASCII Bell character to the console, like this:


 public class testBeep {
  public static main(String args[]) {
     // ASCII bell
     System.out.print("\0007");
     System.out.flush();
     }
  }

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();
     }
  }
