In conclusion, the use of Vector in Java is primarily justified when thread safety is a critical requirement or when working with legacy code that relies on Vector. Additionally, if your application specifically requires support for Enumeration or frequent resizing of the collection, Vector can be a suitable choice.Vector is slow compared to ArrayList. Vector operations gives poor performance as they are thread-safe, the thread which works on Vector gets a lock on it which makes other thread wait till the lock is released.
