Educational Java Applet Service (JAS) provides a collection of educational applet programs and associated educational materials (such as exercise and quiz questions, tutorials, etc.) in the area of solid state materials and devices.  

We would like to receive comments, specific or general in nature, from the users of this resource. Comments pertaining to the specific aspects of applet programs and related materials such as quiz questions and tutorials will be particularly welcome. Your input will help make this resource more useful for the educational community.  Thank you for taking time to send your comments.

About your web browser to view the Applets in this site

• Applets marked with Java2 require a Java2 plugin to run.  The browsers, Netscape and InternetExplorer, handles the installation of Java2 plugin automatically.  Simply respond with "yes" when prompted for the installation.
• Applets marked with Java1.1 require a web browser -- InternetExplorer 5 or a newer version; or Netscape 4.7 or a newer version.
• If not marked with Java1.1 or Java2,  they are viewable in almost any browser.

Three layers of re-usable software components (or objects) may be considered. The three layers are (1) solid-state API for Java programmers; (2) solid-state JavaBeans for application developers; and (3) solid-state applets for educators and trainers. In this project we are focusing on the solid-state API and the solid-state applets. The JavaBeans layer is not part of our current effort.

The solid state applets are reused by trainers and educators in composing their html pages, presentation materials, homework materials, or quizes. The solid state library classes are reused in writing the solid state applets (or applications). This is done by programmers who are familiar with the Java syntax and the object-oriented programming concepts. The solid state API is for our own use in writing the solid-state applet programs. Developed solid state applets may be disseminated via WWW and/or via CD-ROM .  A beta version of a software development Framework (a Framework captures reusable architechural designs and the reusable Java components into an organized applet development context) is also ready.  A Framework adds reusable designs to the reusable components of object-oriented software.  The design reusability seems to be a good and effective way when writing many programs in a given application domain.  Feb.2001- CRW
