This is what I do...
FeatureItertor iter = allFeatures.features();
try {
while (iter.hasNext()) {
SimpleFeature feature = (SimpleFeature)iter.next();
Geometry geom = (Geometry) feature.getAttribute("shape"); //
where shape is geom attribute name in this example
for (Coordinate coord : geom.getCoordinates()) {
doSomethingWonderful(coord);
}
}
} finally {
iter.close();
}
You might also like to look at the JTS CoordinateFilter interface
which can make things simpler sometimes. There's a basic example in
the users guide:
http://docs.codehaus.org/display/GEOTDOC/04+Using+CoordinateFilter+to+implement+operations
Also if you know what your geometry sub-class is (e.g. Polygnon) you
might do something like this...
Polygon poly = (Polygon) feature.getAttribute("attrName");
LineString outerShell = poly.getExteriorRing();
for (Coordinate coord : outerShell.getCordinates()) {
...
}
Have a look at JTS docs for more info:
