It's a dynamically-sized list of objects of the same type stored contiguously in memory.

So an ArrayList?

[–] [email protected] 10 points 10 months ago* (last edited 10 months ago) (1 children)

No. ArrayList is thread safe and implements the collections API. Vector doesn't. Though if you're using Java, there's almost no instance where you would want to use a Vector instead of ArrayList.

ArrayList isn't thread-safe, though...

[–] [email protected] 1 points 10 months ago (1 children)

Thread safe as in it raises an exception instead of breaking your list.

[–] [email protected] 1 points 10 months ago (1 children)

Only if one thread modifies it while another one is iterating over it, if two threads try to modify the list at once there isn't any kind of synchronization and it really could break your list.

For everything else, there's Collections.synchronizedList(new ArrayList<>())
