// Name: Using Parameters
// Description:Description: This is a simple java applet that shows how to get parameters from the html file and use them inside java. Remember Java is case sensitive, so the names in the html file must match your getParameter() names. Ex. html-PARAM NAME=Text Java-getParameter("Text"). It also shows how to convert hex color inputs to RGB color to use in Java.
