Of the enhancements introduced with Java's version 2, the improvements to the user interface are the most extensive. The introduction of Swing, Java 2D, and related class libraries enable more sophisticated interaction between a user and a Java program.
One of the most dramatic changes involves how Java programs work for people who need assistive technology in order to interact with their computers.
The Accessibility classes included as a standard part of Java 2 make it possible for Java programs to work in conjunction with products such as Braille terminals, screen readers, and speech recognition systems.
These classes also offer features that benefit everyone who uses a Swing- developed interface in a Java program.
