The "static import" mechanism is introduced in j2se 1.5. With this mechanism, you can use static members by skipping the class or interface name. This article describes how to use this mechanism and the precautions during use.
In Java programs, independent functions and constants are not allowed to be defined (of course, to be precise, only variables modified by final and assigned only once. Even from the perspective of their own functions, you do not
The more code you find, the more messy the import. You can only manage the module import.
Module search path
The search path of the module is placed in SYS. in the path list, if the default sys. the path does not contain its own module or package path. You can add it dynamically (sys. path. apend. The following is how SYS. Path is added on Windows.
1. The first path of SYS. Path is usually the directory of
In the fifth chapter of high-performance web design, I briefly mentioned that @import had some negative impact on the performance of the site, and then I explored the issue in the Web 2.0 Expo speech and created some test pages and HTTP waterfall charts, which will be used below. The bottom line for this question is: if you want the stylesheet to load in parallel to make the page faster, use link instead of @import.LINK vs. @importAs you all know, the

Preface
There are two ways to organize python modules. One is a simple python file, the file name is the module name, the other is a package, and the package is a directory containing several python files, the directory must contain a file.__init__.pyIn this way, the directory name is the module name, And the python file in the package can also be imported using the package name. File Name method.
This article briefly introduces File Import in HTML, including loading jQuery, execution sequence after import, and other knowledge points, you can refer to Template, Shadow DOM, and Custom Elements to make it easier to create a UI component. However, resources such as HTML, CSS, and JavaScript still need to be loaded one by one, which is inefficient.
It is not easy to delete duplicate dependencies. For ex
The use of export and import in MEF is essentially the process of instantiating an object. Through the features of MEF, the direct dependency of the object is reduced, this allows the system design to achieve a highly flexible and scalable effect.

Recently in the "Python Source code Analysis", Python internal operating mechanism than previously understood deeper into the, feel that they have the opportunity to do a small dynamic scripting language, hehe, of course, is bragging. The goal, of course, is not to create a dynamic language with only one purpose: better use of python. See module import that piece of time, finally to the module import mechan
HBase quick data import-BulkLoad
Apache HBase is a distributed, column-oriented open source database that allows us to access big data at random and in real time. But how can we effectively import data to HBase? HBase has multiple data import methods. The most direct method is to use TableOutputFormat as the output in MapReduce jobs or use standard client APIs. H
