Just likeHashMap,LinkedHashMapperforms the basicMapoperations of add, remove and contains in constant-time, as long as the hash function is well-dimensioned. It also accepts a null key as well as null values. However, thisconstant-time performance ofLinkedHashMapis likely to be a little wors...
class offers constant time performance for the basic operations (add, remove, contains and size). it does not guarantee that the order of elements will remain constant over time iteration performance depends on theinitial capacityand theload factorof the HashSet. It's quite safe to accept defaul...
