Java LinkedHashSet is a class that implements the Java Set interface and stores unique elements in the order they were inserted. It is backed by a hash table and a linked list, providing both fast lookups and predictable iteration order. Introduced in Java 1999 with Java 1.4, LinkedHashSet is part of Java's Java Collections Framework and is useful when both uniqueness and insertion order matter, such as in maintaining ordered collections without duplicates.
