Implements IJavaObject IJavaPeerable IMap IDisposable RemarksHash 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. This linked list ...
java.util.LinkedHashMap<K,V> Type Parameters: K- the type of keys maintained by this map V- the type of mapped values All Implemented Interfaces: Serializable,Cloneable,Map<K,V> public classLinkedHashMap<K,V>extendsHashMap<K,V> implementsMap<K,V> ...
For example, //LinkedHashMap with default capacity and load factor LinkedHashMap<Key, Value> numbers1 = new LinkedHashMap<>(); By default, the capacity of the linked hashmap will be 16 the load factor will be 0.75 Note: The LinkedHashMap class also allows us to define the order of ...
For example, this override will allow the map to grow up to as many as 100 entries and then it will delete the eldest entry each time a new entry is added, maintaining a steady state of 100 entries. private static final int MAX_ENTRIES = 100; ...
