null pointer exception

I'm not sure what i'm doing wrong i create a class in point.java called point that looks like:
public final class point
{
      private int x;
      private int y;
}

Then in another class called Distance.java i have my main method that looks like:
public class Distance
{
      public static void main(String[] args)
      {
            int size = 2048;
            point[] Parray = new point[size];
            Parray[0].x=4;
               }
}
at the line Parray[0].x=4; i keep getting the following error:
Exception in thread "main" java.lang.NullPointerException
I'm not sure what i'm doing wrong
