General

There are three kinds of exception:

• Checked exceptions, which should be caught

• Runtime exceptions, application exceptions which can't be predicted and need not to be caught

• Errors, for problems from outside the application scope

Throwing Exceptions

Any class which extends from Throwable can be thrown:

throw new Exception();

This can be done at any point. But checked exceptions will need to be caught or declared.

Exceptions and Flow Control

Exceptions should be used to handle exceptional cases. Not for flow control.
