Java basics-Use of static keywords, java-static keywords I. Functions of static keywords Make the class members completely independent from any objects of the class. Generally, a class member must be accessed through its class object, but the static modified member can be accessed by itself without referencing a specific instance.

In Java, this usually refers to the current object, or to a member of the current object, and you can use this for this purpose. Another use of this is to invoke another constructor of the current object.The most common scenario is that a parameter name in your method has the same name as a member of the current object, so you need to explicitly

Channels are used in concert with the buffer in NIO. A channel is a bidirectional channel that is readable and writable. It is a bit similar to stream, but stream is unidirectional, the application does not directly perform read/write operations on the channel, but must use the buffer. For example, when reading a channel, you must first read the data into the corresponding buffer and then read it in the buffer. An example of using filechannel Package

AppFuse is an open source project and application that uses open source tools built on the Java platform to help us develop WEB applications quickly and efficiently. I originally developed it to reduce the unnecessary time it takes to build a new WEB application for a customer. At the core, AppFuse is a skeleton of the project, similar to what the IDE creates when you create a new Web project through a wizard. When we create a project using AppFuse, i
