* The write() method takes a message, formats it using the |
| 111 |

< |
* using the text area. The source is usually the |
| 113 |
< |
* calling object, referenced by `this'. The method has been |
| 114 |
< |
* made synchronized to avoid it being called by two different |
| 115 |
< |
* objects and the output ending up merged on the screen. |
