• Java is a Web programming language developed by SUN Microsystems

• A Java applet is a Java program which runs in a Web browser

• A Java program runs locally within java-capable Web browsers as an applet or
  a stand-alone application

• A Java applet starts up by simply clicking on a hypertext reference to it

• Java uses a new paradigm for Web client-server computation
