First, a demo programJava's regular expression package is Java.util.regex, mainly using the pattern and matcher.The GroupCount method is callable, and most methods must be called after the match attempt succeeds.The main methods are:Boolean find ()The Boolean value returned indicates whether a match can be found, and if there are multiple calls, try a new match each time after the last matching position.public class Regex {public static void Main (

Use Builder mode to build a car, and builder mode to build a car
Builder mode can also be used for car creation.
For the Builder model, the prime minister wants to determine the car to be built:
public class Car { public string Model { get; set; } public string Engine { get; set; } publ
There are many examples of builder in life, and personally feel that college life is the best experience of a builder model: to complete a university education, the university education process is generally divided into 4 semesters, so no study can be seen as a part of the construction of a complete university education process, Each person has a different final result after the 4-year (4-phase) build proce
Separating a complex build from its presentation allows the same build process to create different representations. [Construction and presentation separation, different representations of construction]The difference from the abstract factory: in the builder model, there is a mentor who manages the builder, the user is in contact with the mentor, and the mentor contacts the
The builder pattern is defined in design mode as a pattern for building complex objects that often require multiple-step initialization or assignment to complete. So, in the actual development process, where do we fit the builder model? It is a good practice to use builder mode instead of multi-parameter constructors.We often face the writing of such an implement
In fact, the builder pattern is to create an inner class in the class and then the outer class constructor passes the pair image of an inner class, and then the return value in the set and get methods in the inner class is an internal class pair image, which makes it possible to implement the builder pattern well. In fact he is like StringBuilder in the append:string a= "a"; A.append ("Wo"). Append ("Shi").
When writing a popup, it can include the OK button, the Cancel button, the title bar, the Close button, the Minimize button, the content, the Maximize button and so on, but the content does not have to exist under different requirements, different requirements need to be free to mix these components, obviously each combination must be repeated coding. Separating these different, easy-to-change components and constructing complex objects step-by-stage with a

It has been more than three years since the previous version of RegEx was released. The newly designed RegEx 3 was released for developers.
The new version is developed based on Silverlight and can be installed locally. It adopts a Metro style similar to windowsphone7.
The new version has two main functions:
Supports complex and Multiple matching and replacement at an unlimited level
The proc
);$regex 4= "/.*?if (Preg_match_all ($regex 4, $return, $matches)) {Print_r ($matches);}else{echo ' 0 ';}
This is OK, not much explanation, understand the PHP code, print to see the effect.
I hope this article is helpful to everyone's PHP programming.

For example, Cocacola.setsodium (35); Before executing this code, the object CocaCola has already been used by other threads, which results in the use of a CocaCola object that is not in the correct state. simply put, the object is created, and the code that sets the state of the object is not atomized. --------------------------------------------------------------------------------------------------

I. Builder (BUILDER) model
The builder model separates the internal representation of a product from the product generation process, enabling a build process to generate a product object with a different internal representation.
Construction of Object Nature
In some cases, an object will have some important properties that cannot be used as a complete product
Builder mode, which separates the construction of a complex object from its representation, this allows you to create different representations for the same construction process. If you need to separate the construction of a complex object from its representation, you can create different tables during the construction process, we need to apply the "Builder mode", also known as "generator mode", to applicab
