What is difference between ArrayList and vector?

[Mohamed Sanaulla]

You mean java.util.ArrayList and java.util.Vector ? if yes, please search in Beginners Forums or Java In General forums >> SearchFirst

Update: I asked for the clarification as this was earlier posted in JavaFX forum.

[Nico Van Brandt]

Literally from the Java API:

ArrayList

(This class is roughly equivalent to Vector, except that it is unsynchronized.)

Vector

Unlike the new collection implementations, Vector is synchronized.

[swapnil kataria]

as said above vector is synchrnoized and 2nd thing vector are accessible by iterator and enumeration both,

[Randall Fairman]

ArrayList is much faster than Vector, and only takes something like 10% more time to access than a simple array. I forget exactly where I saw this, but it wouldn't be a very hard thing to verify for yourself.

[Rob Spoor]

Much faster? Perhaps a few Java versions ago when the (mostly unnecessary) synchronization had a bigger performance hit, but these days the difference in performance is probably minimal.

There are a few differences between arraylist and vector. Visit this link for the differences:

You do realize that you've replied to a post that's nearly two years old? I suspect Mary has left the building.
