Today a general understanding of Java source file structure, a rough introduction.The source code for the Java language consists of one or more compilation units (compilation unit), each containing a package statement: The package in which the Declaration class resides, and the import statement: Introducing a class from a specific package before all class definitions are placed on it.

Modules Packages (* * * * * *) module (modue) Concept:In the development of computer programs, as the program code more and more, in a file code will be more and more long, more and more difficult to maintain.In order to write maintainable code, we grouped many functions into separate files so that each file contained relatively few code, and many programming languages used this way of organizing code. In Python, a. py file is called a module.What ar

Import special jar settings In general development may look at the source code of the API, you can sometimes imitate the code in the API to do some research, but some special jar packages in the class report can not import errors: The import Sun.misc.ProxyGenerator is never used-Access restriction:the type ' proxygenerator ' isn't API (restriction on required library ' C:\program Files\java\jdk1.7.0_75\jre\lib\rt.jar '. For example, the Proxygenerator

We are generally accustomed to using MAVEN to manage and compile projects and rarely build a MAVEN environment on the server when deployed. When you deploy a project, you need to add a lot of dependencies and hundreds of jar packages to the project's library. In general, we will think of adding the jar package to the Classpath directory, as follows: 1, go to the directory of the configuration file: cd etc [Root@db etc]# VI Profile 2. If you have al

To prevent code decompilation, android introduces the concept of obfuscation code. 1. Set ObfuscationFind the project. properties file under the project. Add proguard. config =$ {sdk. dir}/tools/proguard/proguard-android.txt in the file: proguard-project.txt this is the system You can also use your own obfuscation file (so that you can configure some of your own items) to copy the proguard-android.txt file to the local project under sdk. dir}/tools/proguard /.

The Python language is very powerful. In addition to classes, there are also the concepts of modules and packages. This is a bit like perl. Here we will briefly talk about packages and modules. I. Python modules The module is actually the concept of library (lib), but it not only contains a series of functions, but also can contain classes. python does not include C languages, include a file directly.

The alternative to this problem is to rewrite the json_decode and json_encode methods of PHP json. The solution to the lack of JSON packages for these two PHP files is mainly to convert arrays, strings, or objects into json data (a special structure format ). The json_encode method is required first. This method converts arrays, strings, and objects into json format. Solution: A. Simple edition: Directly address your own problems (you only need to ope
