Java LinkedHashMap<K,V> is a class that extends Java HashMap and maintains the order of insertion or access of its key-value pairs. It is part of Java's Java Collections Framework and provides predictable iteration order, unlike Java HashMap. Introduced in Java 1999 with Java 1.4, LinkedHashMap is widely used for implementing caching algorithms or for maintaining ordered mappings between keys and values in Java applications.
