Create a polygon from point cloud

I have a point(x,y) array and i want to use it to see if a point (x2,y2) is in the polygon created my the point cloud. How can I check it?

I found http://www.pointclouds.org/documentation/tutorials/hull_2d.php but I really don't know how to do he same with Java.

The only real goal is to create a method to check if a point is in or out of the polygon, I don't really need to create the polygon I think.

Just use java.awt.Polygon. The constructor to create Polygon

public Polygon(int xpoints[], int ypoints[], int npoints)

Than use either of

public boolean contains(Point2D p)
public boolean contains(double x, double y)

passing the point x and y
