[Geotools-gt2-users] looking for 2 functions

[<glo...@gm...>]

Hi!
I want to implement two functions using Geotools2.0-Eclipse:
One function to add up the number of points of a .shp file.
One function to calculate the area included between a list of points of a
.shp file.

But I'm new using geotools and I don't know if already exist functions which
work like the two above or which are similar.
Could you help me?Thanks.

I'm sorry about my english!

Gloria
