Java Accessibility Overview
Java SE provides Java Access Bridge, Java Accessibility API (JAAPI), and Java
Accessibility Utilities to enable you to create accessible applications.

Java Access Bridge
Java Access Bridge enables certain Java applications to be visible to assistive
technologies on Microsoft Windows. See Enabling and Testing Java Access Bridge.
Java Accessibility API
The Java Accessibility API (JAAPI), contained in the javax.accessibility
package, is one of the core parts of the Java Foundation Classes (JFC). The JFCs are
a comprehensive set of graphical user interface components and foundation services
designed to simplify deployment of Internet, intranet and desktop applications. JAAPI
enables you to create Java applications that are accessible to persons with disabilities.
Accessible Java applications are compatible with assistive technologies, such as
screen readers, screen magnifiers, speech recognition systems, and refreshable
braille displays. The JAAPI makes GUI component information available to assistive
technologies, giving users alternative presentation and control of Java applications.
Support for JAAPI is built into Swing components; see How to Support Assistive
Technologies in The Java Tutorials (Java SE 8 and earlier).
Java Accessibility Utilities
Java Accessibility Utilities, which is contained in the package
com.sun.java.accessibility.util, is a set of utility classes that help assistive
technologies provide access to GUI toolkits that implement the Java Accessibility API.
Java Accessibility Utilities monitor events related to UI components. They also help
assistive technologies get additional information about a GUI, such as the current
position of the mouse, or the window that currently has focus. See Java Accessibility
Utilities Overview.
Pluggable Look and Feel
The Java Foundation Classes implement a Pluggable Look and Feel architecture.
This architecture allows non-visual manifestations of a user interface to replace or
enhance the visual presentation of an application. The expression of the user interface
is separated from the underlying structure and data of each individual component. This
is accomplished by separating the user interface of the component from its model. The
model of a component is the structure which encapsulates the state and information
