Emit a beep
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("\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();
}
}
