As mentioned in our introduction to the Pattern and Matcher classes, the Java regular expression API has been designed to allow a single compiled pattern to be shared across multiple match operations. Our examples focussed on creating multiple Matche…

http://docs.oracle.com/javase/tutorial/essential/regex/index.html This lesson explains how to use the java.util.regex API for pattern matching with regular expressions. Although the syntax accepted by this package is similar to the Perl programming l…

Principle The presence of the synchronized modifier in a method declaration is an implementation detail, not a part of its exported API. To enable safe concurrent use, a class must clearly document what level of thread safety it supports. Immutable •…

Writing thread-safe code is managing access to state and in particular to shared, mutable state. Object's state is its data, stored in state variables such as instance or static fields. Whether an object needs to be thread-safe depends on whether it…

Thread Safety in Java is a very important topic. Java provide multi-threaded environment support using Java Threads, we know that multiple threads created from same Object share object variables and this can lead to data inconsistency when the thread…

Regular expressions are a powerful language for matching text patterns. This page gives a basic introduction to regular expressions themselves sufficient for our Python exercises and shows how regular expressions work in Python. The Python "re"…

小结: 1.基于java并发模型 Scala concurrency is built on top of the Java concurrency model. 2. 将每个请求放入一个新的线程 The main drawback with this code is that only one request at a time can be answered! You could put each request in a Thread. Simply change (new Handler…

Many text editors have advanced find (and replace) features. When I’m programming, I like to use an editor with regular expression search and replace. This feature is allows one to find text based on complex patterns rather than based just on literal…
