Used whenever u want to be alerted when a value is changed.

whenever you can't be bothered to roll the Observer pattern yourself, and don't care if it's suited to your problem or not, or even works properly

Take a print spooler for example... it might extend Observable... so that client applications (observers) can recieve notifications from the pinter.

Wouldn't it be nice if the porkchop who keeps printing on Letter gets notified in msWord (or more likely msProject)... "Hey porkchop this printer only has A4 paper!"
