The doc page is here
http://docs.geotools.org/latest/userguide/library/coverage/grid.html
And provides an example of "evaluate" on a coverage:
GridCoverage2D coverage = reader.read(null);
// direct access
DirectPosition position = new DirectPosition2D( crs, x, y);
double[] sample = (double[]) coverage.evaluate( position ); // assume double
// resample with the same array
sample = coverage.evaluate( position, sample );
