java 中列表元素删除，如ArrayList

ArrayList list = (ArrayList) lbsBSDAO.getNearbyStopsByDistance(longitude,latitude,distance);
LBSBusStop busStop = null;
int size = list.size();
for (Iterator it = list.iterator(); it.hasNext();) {
busStop = (LBSBusStop)it.next();
double x = Math.abs(busStop.getLongitude() - longitude);
double y = Math.abs(busStop.getLatitude() - latitude);
if(x<0.00000001 && y<0.00000001){
it.remove();
}
}
return list; //lbsBSDAO.getNearbyStopsByDistance(longitude,latitude,distance);
