Collection in Java for Automation Tester

Key Components
Interfaces:
Define the basic operations that can be performed on collections.
Collection: Root interface for collections of objects.
List: Ordered collection that allows duplicate elements (e.g., ArrayList, LinkedList).
Set: Collection that does not allow duplicate elements (e.g., HashSet, LinkedHashSet, SortedSet).
Queue: Collection designed for holding elements prior to processing (e.g., PriorityQueue).
Map: Interface for storing key-value pairs (e.g., HashMap, LinkedHashMap, TreeMap, SortedMap).
Classes:
Implementations of the collection interfaces, providing concrete data structures.
ArrayList: Resizable array implementation of the List interface.
LinkedList: Doubly-linked list implementation of the List and Deque interfaces.
HashSet: Implementation of the Set interface using a hash table.
LinkedHashSet: Implementation of the Set interface that maintains insertion order.
TreeSet: Implementation of the SortedSet interface using a tree structure.
HashMap: Implementation of the Map interface using a hash table.
LinkedHashMap: Implementation of the Map interface that maintains insertion order.
TreeMap: Implementation of the SortedMap interface using a tree structure.
PriorityQueue: Implementation of the Queue interface using a priority heap.
Stack: LIFO (Last-In, First-Out) data structure, subclass of Vector.
Vector: Dynamic array, similar to ArrayList, but synchronized.
