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...
Integer key = iterator.next(); System.out.println("Key: " + key + ", Value: " + pairs.get(key)); } //Remove example pairs.remove(3); System.out.println(pairs); System.out.println(pairs.containsKey(1)); //containsKey method System.out.println(pairs.containsValue("B")); //contain...

我们知道,当accessOrder标志位为true时,表示双向链表中的元素按照访问的先后顺序排列,可以看到,虽然Entry插入链表的顺序依然是按照其put到LinkedHashMap中的顺序,但put和get方法均有调用recordAccess方法(put方法在key相同时会调用)。 recordAccess方法判断accessOrder是否为true,如果是,则将当前访问的Entry(put进来的Entry或g...
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.

LinkedHashMap():initializes a default LinkedHashMap implementation with the default initial capacity (16) and load factor (0.75). LinkedHashMap(int capacity):initializes a LinkedHashMap with a specified capacity and load factor (0.75).
Modified methods: apply, getOrElse, getOrElseUpdate, put Sorry, something went wrong. Copy link szeigercommentedJan 17, 2019 "changes" is an understatement - it's a completely new implementation. I think the idea here is to start with a copy of the new HashMap implementation and make the...

Note that this implementation is not synchronized. 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. This is typically accomplished by synchronizing on some object that naturally encapsulates the...
