HotJava

    A modular, extensible web
   browser from Sun Microsystems that can execute programs
   written in the Java programming language.  These programs,
   known as "applets", can be included (like images) in HTML
   pages.  Because Java programs are compiled into machine
   independent bytecodes, applets can run on any platform on
   which HotJava runs - currently (December 1995)
   SPARC/Solaris 2 and Intel 80x86/Windows 95, Windows
   NT.
