relative to the root of the drive? For example,
d:\folder\otherfolder\file.dat should result in \folder\otherfolder\file.dat
.

I am getting compiler warnings when using Vectors now, so I want to get rid
of them by adding generics to my Vectors.  Online it says to use the
following syntax:
 Vector <Integer> v = new Vector();

Should I use a bounding box or is there and easier way?

I am working on a single-threaded simulation project, but I don't know

I've just run

and I get the following.

I have looked at the interfaces and javadocs for java.util.ArrayList
and java.util.Vector and I can't tell the difference between them.  Is
