Jan 15, 2023 · ArrayList in Java is a concrete class of the List interface that was introduced in the JDK 1.2 version and is available in the java.util package. An ArrayList is used to store a dynamically sized collection of elements. An ArrayList grows in size automatically. Elements can be added, modified, and removed from an ArrayList whenever there is a need. 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. ArrayList is not a legacy class. Vector is a legacy class. ArrayList uses iterator to traverse the elements. Oct 15, 2023 · One of the most notable differences between Vector and ArrayList lies in synchronization. Vector is synchronized, meaning it is thread-safe. Consequently, it incurs a performance hit as it needs to lock the object for each individual operation. // Vector is synchronized Vector<Integer> vector = new Vector<>(); 📌.
