HotJava is a Web browser that supports dynamically downloadable interactive content. Alpha version of HotJava expected to be replaced by major rewrite
Arbitrarily sophisticated dynamic multimedia applications inserts called Applets can be embedded in the regular HTML pages and activated on each exposure of a given page.
Applet constructs are implemented in terms of a
  • special HTML tag: <APPLET codebase="URL directory path" code="Java class file name" width=".." height=".." >
  • where the URL and class file name points to a chunk of server side software that is to be downloaded and executed at the client side on each presentation of a page containing this applet which executes in window specified in size by width and height in picxels.
Applets are written in Java -- a new general purpose object-oriented programming language from Sun Microsystems.
