Foil 18 <param> Tags and Applets

From Introduction to Java to be used in (Scientific) Computing CEWES Java Tutorial -- Spring Semester 98. by Geoffrey C. Fox, Nancy McCracken


The applet tag can be followed by parameters:
  • <applet . . . >
  • <param name=attributename1 value="attributevalue1" >
  • .......
  • <param name=attributenameN value="attributevalueN" >
  • </applet>
The Java program accesses this information by
  • String attribute;
  • attribute = getParameter("attributename1");
  • if( attribute == null )
  • attribute = yourdefaultvalue;
  • // null is Java way of saying unset
Typically this processing would be in init() method of Applet
