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<>(); 📌. Vector. 1) ArrayList is not synchronized. Vector is synchronized. 2) ArrayList increments 50% of current array size if the number of elements exceeds from its capacity. Vector increments 100% means doubles the array size if the total number of elements exceeds than its capacity. 3) ArrayList is not a legacy class. It is introduced in JDK 1.2.Two such popular Java collections are the Arraylist and the Vector. Overview of Java.
