NettetA default LinkedHashSet has an initial capacity of 16 and a load factor of 0.75. This means that once there are 12 elements in the LinkedHashSet, it will double its capacity to accommodate more elements. If we can assume that hashes are evenly distributed, a larger capacity means a lower probability of a collision.

I understand how HashSet can provide constant-time performance for remove(Object obj), but since LinkedHashSet needs to maintain a linked list as well, and removing a specific element involves traversing the list, then it seems to me that remove(Object obj) should take linear time. NettetLinkedHashSet: LinkedHashSet extends HashSet class and implements Set interface. Like HashSet, it also represents a group of unique objects but it maintains insertion order for them. Example

LinkedHashSet (int … NettetA linked hash map has two parameters that affect its performance: initial capacity and load factor. They are defined precisely as for HashMap. Note, however, that the penalty for choosing an excessively high value for initial capacity is less severe for this class than for HashMap, as iteration times for this class are unaffected by capacity.
