What is a collection in Java?
Java Collection framework provides many interfaces (Set, List, Queue, Deque) and classes ( ArrayList, Vector, LinkedList, PriorityQueue, HashSet, LinkedHashSet, TreeSet). A Collection represents a single unit of objects, i.e., a group. It provides readymade architecture. It represents a set of classes and interfaces. It is optional.
What are the methods of Collection interface?
Some of the methods of Collection interface are Boolean add ( Object obj), Boolean addAll ( Collection c), void clear (), etc. which are implemented by all the subclasses of Collection interface. List interface is the child interface of Collection interface.
