Text processing often involves matching text against a pattern. Although Java s character and assorted string classes offerlow- levelpattern- matching support, that support commonly leads to complex code. To help you write simplerpattern- matching code, Java provides regular expressions. After introducing you to terminology and thejava.util. regex package, Jeff Friesen explores many regular expression constructs supported by that package s Pattern class. Then he examines Pattern s methods and the additionaljava.util. regex classes. In conclusion, he presents a practical application of regular expressions.
Java Regex Primer Since version 1.4, Java has had support for Regular Expressions in the core API. Java Regex follows the same basic principles used in other languages, just withdi erent access methods, and some subtledi erences with the patterns. This primer is aimed towards developers already familiar with regex in other languages wanting a brief outline of its support in Java. It may also be beneficial to developers learning regex if used in conjunction with detailed documentation explaining the construction of regex patterns. Reading the javadoc forjava.util.regex. Pattern is a must to see how the Java regex patterns aredi erent from other languages such as Perl. Most of the functions discussed herin are from thejava.util.regex. Matcher class with a few fromjava.util.regex. Pattern. Reading this text in conjunction with the javadoc of those classes is advised.
FullThreadDump demonstrates the use of the java.lang.management API
to print the full thread dump. JDK 6 defines a new API to dump
the information about monitors and java.util.concurrent ownable
synchronizers.

radius協議源碼÷The Radius Stack will connect to a Radius Server. This stack
implementation is built upon the UdpStack which is available
in the radius{version}/util directory. A minimal set of VSAs (Vendor
Specific Attributes are supported by this stack). The Radius
Stack should be used as a base class. In order to implement
a larger set of VSAs, one will need to subclass from the
Radius Stack and implement the functionality within the
virtual function processVsa(). The Radius Stack supports
mostly accounting messages. The authentcation messages
will be supported in a future release.
A test program has been provided in the radius directory.
This program shows how to subclass from the RadiusStack
and how to use the api.
