> 1.  What is the difference between a pointer and a reference?

Nothing.

> 2.  If Java does not have pointers, what is a NullPointerException?

Java has pointers, it just doesn't have pointer arithmetic (i.e. you can't
change the pointer's value). Perhaps we should think of Java's references as
immutable pointers.
