* Exceptions may be thrown by one part of a Java program and caught

* The root class of all exceptions worth catching in a program. This
* includes the special category of <code>RuntimeException</code>, which
* does not need to be declared in a throws clause. Exceptions can be used
* to represent almost any exceptional behavior, such as programming errors,
* mouse movements, keyboard clicking, etc.
