"NettetIt is slow as compared to HashMap because it uses Doubly Linked list internally which result into Time and space complexity overhead. TreeMap is also not Thread-Safe because it is not synchronized. It is slow as compared to HashMap and LinkedHashMap because of sorting operations as Comparator will be called for sorting purpose.

HashMap vs LinkedHashMap vs TreeMap vs HashTable in Java

NettetLinkedHashSet performance is slow as compared to TreeSet except insertion and removal operations. LinkedHashSet performance is almost similar to HashSet but … NettetConstructs an insertion-ordered LinkedHashMap instance with the same mappings as the specified map. The LinkedHashMap instance is created with a default load factor (0.75) and an initial capacity sufficient to hold the mappings in the specified map. Parameters: m - the map whose mappings are to be placed in this map.
