Problem using GeotiffWriter

I'm a serious Java newbie, so be gentle if I've done something stupid 
here...

I wrote the attached short program, which is based off of a post to this 
list last year, to read a single element from a netCDF file, and write a 
GeoTIFF file, however, I get the following error message when I try to 
compile it with javac...

GeoTifWriter.java:16: cannot resolve symbol
symbol  : method writeGrid 
(java.lang.String,java.lang.String,int,int,boolean)
location: class ucar.nc2.geotiff.GeotiffWriter
     writer.writeGrid("/home/mwfoster/MaxT_test.cdf", "MaxT_SFC", 0, 0, 
false);
           ^

The "caret" symbol is actually under the dot between writer and 
writeGrid, in case a variable-width font messed that up.

Can someone help me out here?

Matt
