所以,如果要将自定义的对象放入到LinkedHashMap或LinkedHashSet中,需要@OverridehashCode()和equals()方法。 Hash table and linked list implementation of the <tt>Map</tt> interface, with predictable iteration order. This implementation differs from <tt>HashMap</tt> in that it maintains a doubly-linked...
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. This linked list defines the iteration ordering, which is normally the order in w...
Implementation Note: The spliterators returned by the spliterator method of the collections returned by all of this class's collection view methods are created from the iterators of the corresponding collections. Since: 1.4 See Also: Object.hashCode(),Collection,Map,HashMap,TreeMap,Hashtable,Serializ...
In access ordered map, keys are sorted on the basis of access order last time they were accessed using any method of LinkedHashMap. Invoking the put, putIfAbsent, get, getOrDefault, compute, computeIfAbsent, computeIfPresent, or merge methods results in an access to the corresponding entry. ...
The spliterators returned by the spliterator method of the collections returned by all of this class's collection view methods are <em>late-binding</em>, <em>fail-fast</em>, and additionally report Spliterator#ORDERED. <em>Note</em>: The implementation of these spliterators in Android Nougat...

If you need to get the value associated with a key, create the iterator from the entrySet() method rather than the keySet method. February 19th, 2008, 02:46 PM dlorde Re: Linked hashMap Iterators Quote: Originally Posted bykeang
The effects of returning true after modifying the map from within this method are unspecified. This implementation merely returns false (so that this map acts like a normal map - the eldest element is never removed). Parameters: eldest - The least recently inserted e...
