Seeing the headline, you might think, what does this have to do with Netty? Indeed, if you are completely using Netty, then you may not need to know selector at all. However, it must be mentioned that the implementation of the Netty underlying NIO is also based on Java selector, which is the encapsulation of selector. Therefore, I personally think that understanding the good selector for the use and understanding of Netty are a lot of helpful. Of cour

hierarchy . Collection represents a set of objects, also known as Collection elements . Some collection allow duplicate elements, while others do not. Some of the collection are orderly, while others are unordered. The JDK does not provide any direct implementation of this interface: it provides more specific sub-interfaces (such as Set and List) implementations. This interface is often used to pass collection and operate these collection where it is required to be the most universal.Collection

When Java 1.0 was just appearing, it included a class library for basic GUI programming, which Sun called the Abstract Window Toolbox (abstract Windows Toolkit, AWT).In 1996, Netscape created a GUI library called the IFC (Internet Foundation Class). Sun worked with Netscape to refine this approach by creating a user interface library called swing.Swing does not completely replace AWT, but is based on the AWT architecture. Swing simply provides a more
