Vector
- Synchronized
- slower as compare to arraylist
- mostly use with single threading
- not allow null
- no duplicate
Array List
- Non-Synchronized
- faster
- multi threading
- allow null value
- allow duplicate -Suthar Jalaram

Now a days vectorlists are not being used only the array lists are being used. vector list are single thread so the execution time will be more than the array list bcoz it will have locking of thread while that thread is being executed.. --Mahesh.p

One more difference between Array List vs Vector is that later is a legacy class and initially not part of Collection API
