This is the superclass of all exceptions thrown by operations in the Context and DirContext interfaces. The nature of the failure is described by the name of the subclass. This exception captures the information pinpointing where the operation failed, such as where resolution last proceeded to. Resolved Name.
Variables should be named using camelCasing. Variable names should always start with a lower case letter. Packages should be named using snake_casing. Package names should always start with a lower case letter.
All identifiers should begin with a letter (A to Z or a to z), currency character ($) or an underscore (_). After the first character, identifiers can have any combination of characters. A keyword cannot be used as an identifier.
There are three types of exception—the checked exception, the error and the runtime exception.
In Java, is there a semantic difference between using "Illegal" (as in IllegalArgumentException) versus "Invalid" (as in javax.activity.InvalidActivityException)?
During the course of an assignment it became useful to write a subclass of IllegalArgumentException to represent a series of input characters that cannot be tokenized, and I'm wondering whether convention says to use InvalidTokenException or IllegalTokenException.
The only difference I can find so far is that java.lang seems to prefer "Illegal" while javax.* prefers "Invalid". However, there is also java.security.InvalidParameterException which is a subclass of IllegalArgumentException.
