Java LinkedHashMap is a class that implements the Java Map interface and maintains the order of insertion or access of its elements. Unlike Java HashMap, which does not guarantee any order of its entries, LinkedHashMap preserves the order in which keys were inserted or accessed. Introduced in Java 1999 with Java 1.4, LinkedHashMap is part of Java's Java Collections Framework and is often used when the order of the elements needs to be maintained along with efficient key-based lookups.
