In short, CopyOnWriteArrayList is a better choice if an array is mainly accessed for reading data but if the number of the write operation is high then sticking with a synchronized list is a better option because the cost of copying list would outweigh the gain made by sacrificing locking. If...

There are fewsimilarities betweenthese classes which are as follows: Both Vector and ArrayList use growable array data structure. The iterator and listIterator returned by these classes (Vector and ArrayList) are fail-fast. They both are ordered collection classes as they maintain the elements insert...
ArrayList in Java is a resizable array with direct indexing, ideal for accessing elements. LinkedList, a doubly-linked list, excels in adding/removing elements, trading off slower random access. Difference Between ArrayList in Java and LinkedList in Java ...
Vector , ArrayList classes are implemented using dynamically resizable array providing fast random access and fast list traversal very much like using an ordinary array . ArrayList support dynamic arrays that can grow as needed that is ArrayList can be dynamically increased or decreased in size . ...
