What are the basic interfaces of Java Collections Framework?
The Java Collections Framework is a comprehensive architecture for representing and manipulating collections, which are groups of objects. Essentially, it provides a set of standard interfaces and implementations that allow collections to be handled in a consistent manner across various types of data structures. Here are the basic interfaces of the Java Collections Framework:
Collection Interface: This is the root interface of the framework and does not extend any other interfaces. It provides basic methods for operations like adding and removing elements, checking the size of the collection, and checking whether an element is present. All other collection interfaces extend this interface[1][2][3][4][5].
List Interface: This interface extends the Collection interface and allows elements to be inserted or accessed by their position in the list. The List interface is ordered and can contain duplicate elements. Examples of classes implementing this interface include ArrayList, LinkedList, and Vector[1][2][3][4][5].
Set Interface: Also extending the Collection interface, the Set interface models the mathematical set abstraction and does not allow duplicate elements. It is primarily used to represent collections that must have unique elements. HashSet, LinkedHashSet, and TreeSet are some of the classes implementing this interface[1][2][3][4][5].
SortedSet Interface: This extends the Set interface and maintains its elements in a sorted order. TreeSet is an example of a class implementing this interface[1].
Queue Interface: Extending the Collection interface, the Queue int...
