feature provides annotations that allow developers to define and use their own annotation types. This feature consists of a syntax that defines the annotation type and a syntax for describing an annotation declaration, an API for reading annotations, a class file with annotation modifications, and a annotation processing tool.
annotation does not directly affect the semantics of the code, but he can be viewed as a tool or class library of the program. It will in turn affect the program semanti

configuration file, and can be one of five states: off, error (Error), Warning (Warning), info (info), and verbose (Verbose). These states are part of the environment, and their values can be from 0 to 4. This way you can create a control for all subsystem information. Define an output switch class and then initialize it to create a switch:

UNIX and MS-DOS stack segments
In Unix, the stack will grow automatically when the process needs more space.
DOS, when an executable is created, the stack size must be determined at the same time

In earlier versions of Apache, the application itself must be able to handle the details of the various operating system platforms and invoke different processing functions for different platforms. With the further development of Apache, the Apache organization decided to separate these common functions and develop them into a new project. In this way, the development

If exception is processed at its own level, the return value is best for the program to continue, but does not further process the numeric value of the data. For example: Return an empty list, then the caller receives the return value, does not break the program, and because the number of returned list is 0, does no
