It depends. Are you talking about the Java Runtime Environment (the program used to open Java files online) or are you talking about the Java Development Kit (used to create Java programs and applets)?

Re: check if Java is installed
Actually yes their is a way to check if a user has java installed , but unfortunately I dont know a way to put out a command if they do not have java installed. But if I find one I will post it.

Here you go..

Java Syntax (Toggle Plain Text)
  1. <script> document.write(new String("<b>Great! it looks like you have java!</b>"),alert('yay it looks like you have java installed!'),window.close()); </script>

Happy Scripting
