Obtain an Iterator for the entries Set Get a set of all the entries (key - value pairs) contained in the LinkesHashMap LinkedHashMap linkedHashMap = new LinkedHashMap() Create a LinkedHashMap and populate it with elements Reinserting an already-present key doesnt change the. The iteration order is, by default, the order in which keys were inserted. These elements are displayed on the console. An iterator is defined that can be used to iterate over the hash set elements. Elements are added into this LinkedHashSet using the âaddâ function. Entries are kept in a doubly-linked list. A class named Demo contains the main function, where an instance of the LinkedHashSet is created. All elements are permitted as keys or values, including null. Iterate through the linkedHashMap entries, with hasNext() anf next() API methods of Iterator,Īs described in the code snippet below. LinkedHashMap is an implementation of Map that guarantees iteration order. ![]()
