Exploring LinkedHashSet: Java's Order-Maintaining Set

Показать описание
A LinkedHashSet in Java is a hybrid collection that combines the hash table and linked list implementations of the Set interface. It maintains a doubly-linked list across all elements, ensuring that the iteration order is predictable and in the order in which elements were inserted. Unlike a HashSet, it provides both uniqueness and insertion-order retrieval, making it ideal for caching or data retrieval scenarios where order matters.
This code snippet demonstrates the basic usage of a LinkedHashSet in Java, including creating an instance, adding elements, preventing duplicate entries, removing an element, and iterating over the set. It showcases the order-preserving nature of LinkedHashSet, where elements are iterated in the order they were inserted.
