However, the vast majority of uses for the Java 2D API utilize a small subset of its capabilities encapsulated in the java.awt.Graphics class. This lesson covers the most common needs of applications developers. Less common needs are described later in the Advanced topics in the Java 2D API....

The Java 2D API includes the java.awt.Graphics2D class, which extends the Graphics class to provide access to the enhanced graphics and rendering features of the Java 2D API. These features include: Rendering the outline of any geometric primitive, using the stroke and paint attributes (draw met...
在Java 1.0 刚刚出现的时候,包含了一个用于基本 GUI 程序设计的类库,Sun将它称为 抽象窗口工具箱( Abstract Window Toolkit, AWT)。基本 AWT 库采用将处理用户界面元素 的任务委派给每个目标平台( Windows、Solaris、 Macintosh 等)的本地 GUI 工具箱的方式, 由本地 GUI 工具箱负责用户界面元素的创建和动作。例如...
