Creating and Enriching Graphical User
The applications presented in previous chapters featured Standard I/O-based user inter-
strating Java features or for interacting with small utility applications (e.g., Chapter 3 ' s
StubFinder application), they are inadequate for more sophisticated needs, such as
create and enrich more sophisticated graphical user interfaces (GUIs).
Abstract Window Toolkit (AWT) is Java's original GUI-oriented API. After introdu-
cing AWT to Java, Sun Microsystems introduced Java Foundation Classes (JFC) as an
sophisticated GUIs), Accessibility (for supporting assistive technologies), Java 2D (for
creating high-quality graphics), and Drag and Drop (for dragging and dropping AWT/
Swing GUI components, such as buttons or textfields).
Chapter7 continuestoexplorethestandardclasslibrarybyintroducingyoutoAWT,
Swing, and Java 2D. Appendix C introduces you to Accessibility and Drag and Drop.
Abstract Window Toolkit
Abstract Window Toolkit (AWT) is Java's original windowing system-independent API
AWT also supports graphics, colors, fonts, images, data transfer, and more.
ThestandardclasslibraryorganizesAWT'smanytypesintothe java.awt package
and subpackages. However, not all java.awt types and subpackages belong to AWT.
For example, java.awt.Graphics2D and java.awt.geom belong to Java 2D.
