1. Java and his APIs can use concurrency. You can specify that the program contains different execution threads, each with its own method call stack and program counter, allowing threads to concurrently execute resources, such as shared memory, that can share the program's scope with other threads, known as multithreaded Programming (multithreading), at the core of C and C This ability is not available in the + + language, although they affect the des

Java: Using Lambda expressions to simplify code example: lambda expressions Previously, the 3rd-party service was called, and every method was almost "long". It was too cool to write, and it was easy to modify and leak. public void authorizeRoleToUser(Long userId, List After learning and extracting encapsulation, I extracted try... catch... to the public and obta

intuitive as calling properties, in addition, the processing speed of XML files is less time-consuming than that of plain text files. However, if we use small relational databases such as access and sqllite to save the poor data, we will not be too busy with the public, and the loss will not be worth the candle. For example, my loonframework-game framework is a java2d game development component. Therefore, it should provide a persistent storage envir

I am developing a map program. I am more willing to use this method than using XML to write Android interfaces,Instead of using the MapView provided by Android, you can use the Google Maps JavaScript API that you have been familiar with before,Load HTML code in Android WebView, and use the powerful interaction between Java and Js provided by Android,Use web pages as interfaces to develop programs.

the book to implement the two patterns is completely different (I think this implementation is somewhat arbitrary). the state mode, in particular, uses a separate implementation hierarchy, but I don't think it's necessary unless you assume that the implementation code is not controlled by you (which is, of course, a possibility, but if the code is controlled by you, It is also more concise and practical wi

Using Java regularization makes it easy to extract eligible content from a string.1. Extract all the phone numbers in the string:private void Getphonenum (String smsbody) { Pattern pattern = Pattern.compile ("(13|14|15|18) \\d{9}"); Matcher Matcher = Pattern.matcher (smsbody); while (Matcher.find ()) { System.out.println (Matcher.group ()); } }2. In Android development, it is sometimes necessary to extract the

Take the pattern string "AABACB" as an example, matching the PAT's DFA state diagram as follows: The corresponding

This article records some code examples that use the annotations feature of the XStream API to convert Java objects to and from XML strings.Many of us have worked with XML files, and there are many very mature third-party open source software. such as:Jdom,dom4j and so on. Although they are very powerful, they are still a bit less accustomed to use. For a fixed-format XML document, its structure does not c

1. Simple Factory Model IntroductionThe Simple factory pattern (simply Factory) is also called the "static factory method pattern." It belongs to the "Create pattern" (the schema that creates the object) and is a special implementation of the "factory method" pattern.Typically, we use a simple factory pattern to create a class. For example, getting a thread pool object is done through a simple factory pattern. Its structure diagram looks like this:
