At any point, we can add elements to the list. In Java, the list allows for the storage of duplicate elements. Three actual subclasses of the list interface are ArrayList, Vector, and LinkedList. Set The set interface is implemented by the classes LinkedHashSet, HashSet, and TreeSet, and...

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.
