sending and receiving addresses are fixed and can be written to death directly, but the sessionId is changed, you need to extract it from the feedback data first, I am using a simple regular expression: String strResult = EntityUtils. toString (httpResponse. getEntity ()); Pattern p = Pattern. compile ("sessionId =. (\ d +)"); // get sessionId Matcher m = p. matcher (strResult ); If (m. find () mSessionId

LookThe final result of the surround look match is a location with four types of surround look:The (? =expression) order is sure to look around, indicating that the right side of the position matches Expression(?! expression) , which indicates that the right side of the position does not match the expression(? in reverse order, which indicates that the left side of the position matches the Expression(? reverse the negative look, indicating that the left side of the position does not match expr

Regular expressions are used in the general way:Pattern: The compiled representation of the regular expression. That is, each pattern object represents a rule! There is no construction method, and the following method is used to return the Pettern object public static pattern compile (String regex) to compile the given regular expression into the pattern. Creates a corresponding pattern object by the given string form public Matcher

Example 1For news content or blog articles, if the abstract is displayed, you need to remove the html format tag of the content, find a regular expression, and implement: The code is as follows:Copy code /*** Delete the html format in the input string * * @ Param input* @ Param length* @ Return*/Public static String splitAndFilterString (String input ){If (input = null | input. trim (). equals ("")){Return ""; } // Remove all html elements,String str = input. replaceAll (

Procedure:1. encapsulate a regular expression into an object.2. Associate the regular object with the string to be operated.3. Obtain the regular expression matching engine after Association.4. Use the engine to perform operations on the sub-strings that comply with the rules, such as extracting them. Import Java. util. regEx. *; Class regexd

Regular Expression Re-pattern function: The function (re-pattern) accepts a string parameter and returns a regular expression style (java. util. regex. Pattern class instance ). This style can be used for regular expression matching. You can also use a macro to directly input a regular expression in text format: Use the # symbol before the string. The expression is the same as that generated using the re-pattern function. For example, the following representation is the same as that in the p

The Java Regular expression string pattern.Regular expressions can be used to search, edit, and manipulate text.Regular expressions are not limited to one language, but are subtle in each language.There are 3 main classes in the Java.util.regex package: Pattern class:The pattern object is a compiled representation of a regular expression. The pattern class has no public constructor method. To create a pattern object, you must first call its public static compilation method, which return

Just having a requirement to extract all the specific characters in a string is tedious if you are dealing with a regular string. So I thought of using regular expressions to do it.

Brief introduction: Java.util.regex is a class library package that uses patterns that are customized by regular expressions to match strings. It consists of two classes: pattern and Matcher Pattern A pattern is a compiled representation of a regular expression. Matcher A Matcher object is a state machine that expands the match
