Exceptional Code

The common attribute of all exceptional code is, not surprisingly, the proper use of exceptions. Exceptions can give your code immense debugging power and provide a base for indicating user errors. At one time, using exceptions for business logic errors was considered to be bad form. Instead of throwing an exception, the programmer was encouraged to use deeply nested if statements to catch user errors. Java has changed this perspective somewhat through the use of two types of exceptions, both of which are covered extensively in this chapter.
