All general-purpose Collection implementation classes (which typically implement Collection indirectly through one of its subinterfaces) should provide two "standard" constructors: a void (no arguments) constructor, which creates an empty collection, and a constructor with a single argument of type Collection, which creates a new collection with the same elements as its argument. Declaration. In the previous article we saw default methods in interfaces and their inheritance rules. In LinkedList, the manipulation is fast because no shifting is required.Vector uses a dynamic array to store the data elements. next → ← prev.

The ArrayList class maintains the insertion order The Iterable interface is the root interface for all the collection classes. It maintains the insertion order and permits null elements.SortedSet is the alternate of Set interface that provides a total ordering on its elements. Java Collections can achieve all the operations that you perform on a data such as searching, sorting, insertion, manipulation, and deletion. List Interface: This is a child interface of the collection interface. It is similar to ArrayList.
