Java LinkedHashMap class is Hashtable and Linked list implementation of the Map interface, with predictable iteration order. It inherits HashMap class and implements the Map interface.
implements Map <K,V> Hash table and linked list implementation of the Map interface, with predictable iteration order. This implementation differs from HashMap in that it maintains a doubly-linked list running through all of its entries.
In this tutorial, we will learn about the Java LinkedHashMap class and its operations with the help of examples. The LinkedHashMap class of the Java collections framework provides the hash table and linked list implementation of the Map interface.
Jan 9, 2024 · In this article, we have explored Java LinkedHashMap class as one of the foremost implementations of Map interface in terms of usage. We have also explored its internal workings in terms of the difference from HashMap which is its superclass.
Constructs an insertion-ordered LinkedHashMap instance with the same mappings as the specified map. The LinkedHashMap instance is created with a default load factor (0.75) and an initial capacity sufficient to hold the mappings in the specified map.
Java LinkedHashMap is a hash table and doubly linked List based implementation of Java's Map interface. It extends the HashMap class which is another very commonly used implementation of the Map interface.
