Java Notes

Beep

A beep sound can be use to indicate a warning or error. However, it is often better to give a warning dialog box with a description of the problem.

To Produce a Beep Sound

You need to import the Toolkit class:
```
   import java.awt.Toolkit;
```
Use this statment in your code:
```
   Toolkit.getDefaultToolkit().beep();
```

This is not always a sufficient way to alert the user as there may not be sound on the user's computer (as in many student labs) or the sound may be turned down, etc.
