![]() LinkedHashMap lhm = new LinkedHashMap() Ģ. LinkedHashMap(): This is used to construct a default LinkedHashMap constructor. The following are the constructors available in this class:ġ. The LinkedHashMap class consists of various constructors that allow the possible creation of the ArrayList. In order to create a LinkedHashMap, we need to create an object of the LinkedHashMap class. This is best done at creation time, to prevent accidental unsynchronized access to the map: Map m = Collections.synchronizedMap(new LinkedHashMap(.)) Constructors of LinkedHashMap Class If no such object exists, the map should be “wrapped” using the Collections.synchronizedMap method. This is typically accomplished by synchronizing on some object that naturally encapsulates the map. If multiple threads access a linked hash map concurrently, and at least one of the threads modifies the map structurally, it must be synchronized externally. The implementation of LinkedHashMap is not synchronized. Previous: This parameter contains the address to the previous node of the LinkedHashMap.Next: Since the LinkedHashMap stores the insertion order, this contains the address to the next node of the LinkedHashMap. ![]() Due to generics, this value can be of any form. This parameter stores the value of the keys. Value: For every key, there is a value associated with it.Therefore, this parameter is the key to the data. Key: Since this class extends HashMap, the data is stored in the form of a key-value pair. ![]()
