o getIntParameter 
  protected final int getIntParameter(String paramName,
                                      int defaultValue)
Returns the integer value of the applet parameter paramName, or defaultValue if the parameter isn`t specified or isn`t an integer.
Parameters:
paramName - the name of the applet parameter whose value is to be returned
defaultValue - the value to be returned if the applet parameter hasn`t been specified or isn`t an integer
o getBooleanParameter 
  protected final boolean getBooleanParameter(String paramName,
                                              boolean defaultValue)

Parameters:
paramName - the name of the applet parameter whose value is to be returned
defaultValue - the value to be returned if the applet parameter hasn`t been specified or isn`t a boolean
o getColorParameter 
  protected final Color getColorParameter(String paramName,
                                          Color defaultValue)
Returns the Color specified by the value of the applet parameter paramName, or defaultValue if the parameter isn`t specified or isn`t valid. (The parameter`s value must be a hexadecimal colour value of the form RRGGBB.)
Parameters:
paramName - the name of the applet parameter whose value is to be returned
defaultValue - the value to be returned if the applet parameter hasn`t been specified or isn`t valid
