Vector is available in JDK 1.0, whereas ArrayList was added in JDK 1.2.  
So if you need to target older VMs, such as a browser VM, you will 
probably want to use Vector.

Vector is synchronized by default, whereas ArrayList is not.  Since 
this adds a significant amount of overhead, you would be better off 
with an ArrayList if you do not need automatic synchronization at the 
level of the List/Vector class.  In most cases, synchronizing at a 
higher level makes more sense.
