I don't remember for sure if there is a convenience method already  
made for this.  You can look at the FeatureUtils class for some  
utility methods dealing with features.  If not then the following  
code snippet should help.  (I haven't compiled it so forgive the typos)

Class type = layer.getSchema().getDefaultGeometry().getType();
Polygon.class.isAssignableFrom( type ) ||  
MultiPolygon.class.isAssignableFrom(type)
