Recently there has been no time to write a blog, things more, quiet heart, things go with its natural good, and some things I do not understand why it will become so, you think you pay the most precious, but perhaps others do not like. Forget it, do not think much, let it be natural.Java does not keep up with C + + in graphic drawing, but I think Java has some advantages in graphics, but for large desktop g

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

Below is an introduction to the graphics of the API documentation! GraphicsClass is the abstract base class for all graphics contexts, allowing applications to draw on components that have been implemented on a variety of devices and on closed-screen images.GraphicsObject encapsulates the state information required for basic rendering operations supported by Java
