Anything reflective is a dead giveaway, and I'm pretty sure that the two 
classes have slightly different sizes, so you could observe differences 
in memory characteristics.

More seriously, the Collections API tweaked some method names 
differently, so there are a few methods in Vector which are kept around 
for legacy use (addElement, e.g.).

In general, an ArrayList is a list that happens to be backed by an 
array. A Vector is a synchronized, automatically-growing array that 
leaks details about its array all over the place; it was shoehorned into 
the Collections API upon introduction to allow for a more gradual, 
correct migration.
