Description: 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. Platform: |

Description: Lex是美国Bell实验室用C语言研制的一个词法分析程序自生成工具。它的基本原理就是使用正则表达式扫描匹配文本，并为每一个匹配模式定义一些操作，当用C语言作宿主语言时，这些操作都由C语言实现。一种匹配的正则表达式可能会包含相关的动作。这一动作可能还包括返回一个标记。当 Lex 接收到文件或文本形式的输入时，它试图将文本与正则表达式进行匹配。它一次读入一个输入字符，直到找到一个匹配的模式。如果能够找到一个匹配的模式，Lex 就执行相关的动作（可能包括返回一个标记）。-Lex Bell Laboratories of the United States with C language developed by a lexical analysis tool generated from the process. Its fundamental principle is to use a regular expression matching text scanning, and for every definition of a matching model for operation, when the C language of the host language, these operators by C language. A match of which is likely to contain expressions related to the moves. This action may also include the return of a marker. When Lex reception of the document or text input, it is trying to text and is a regular expression matching. It read an input into the characters, until they found a matching pattern. If they can find a matching model, Lex on the implementation of the action (which may include a return of markings). Platform: |

Description: 代码号为”Merlin”的J2SE1.4带来了一些激动人心的新特性,诸如对正则表达式的支持,异步输入输出流,通道(Channel),字符集等.虽然该版本还处在测试阶段,但这些新特性早已让开发人员们跃跃欲试.在Merlin发布之前,异步输入输出流的应用还只是C,C++程序员的特殊武器 在Merlin中引入异步输入输出机制之后,Java程序员也可以利用它完成很多简洁却是高质量的代码了.本文将介绍怎样使用异步输入输出流来编写Socket进程通信程序.-code, as "Merlin" J2SE1.4 brought some exciting new features, such as the right is a regular expression support, asynchronous input and output streams, channel (Channel), such as character set. Although this version is still in the testing stage, but these new features make the developers who the dismissive. before the publication of the Merlin, asynchronous input and output streams of only C, C programmer in the special weapons Merlin introduced asynchronous input-output mechanisms, Java programmers can also use a lot of it is simple but high-quality code. this article will introduce how to use asynchronous losers into the output stream to the process of preparing Socket Communication Program.

Description: 程序用JAVA语言编写, 综合利用图结构和堆栈结构进行数据组织和处理. 可以进行正则表达式到NFA的转化, 并能用图形直观的表示.
对正则表达式有一些约定, 就是可以用单个字符表示输入, 也可以用 ‘ ‘ 连接起来的一串字符进行输入. 有基本的表达式以及由基本表达式构成的并置, 选择和重复的操作.
例:
A|b*c
‘letter’*’digit’
等都是合法输入. 还带有括号功能, 优先级
-procedures using Java language. Comprehensive Utilization graph structure and stack structure and data processing. it is a regular expression for NFA to the transformation and can use the intuitive graphical said. Regular expressions are to some agreement and it is expressed with a single character input, we could also use '' linking the string of characters for importation. a basic expressions and by the basic form of expression and Home and choose and repeat the operation. cases : A | b* c 'letter'* 'digit' are all legally imported. also bracketed with functionality, prioritized Platform: |
