At page 427 of the SCJP Study Guide (1.4) by Kathy Sierra and Bert Bates, one can read about LinkedHashSet the following:
LinkedHashSet lets you iterate through the elements in the order in which they were inserted. Optionally, you can construct a LinkedHashSet so that it maintains the order in which elements were last accessed, rather than the order in which elements were inserted.
What are the constructors/methods that let you construct a LinkedHashSet "so that it maintains the order in which elements were last accessed"?, cause I could not find anything in the API. All the API says is:
This linked list defines the iteration ordering, which is the order in which elements were inserted into the set insertion-order).
Its constructors are:
LinkedHashSet() - Constructs a new, empty linked hash set with the default initial capacity (16) and load factor (0.75).
LinkedHashSet(Collection c) - Constructs a new linked hash set with the same elements as the specified collection.
LinkedHashSet(int initialCapacity) - Constructs a new, empty linked hash set with the specified initial capacity and the default load factor (0.75).
LinkedHashSet(int initialCapacity, float loadFactor) - Constructs a new, empty linked hash set with the specified initial capacity and load factor.
I see nothing like LinkedHashMap's contructor that lets you construct the map so that is order by access:
LinkedHashMap(int initialCapacity, float loadFactor, boolean accessOrder) - Constructs an empty LinkedHashMap instance with the specified initial capacity, load factor and ordering mode.
Somehow you got a hold of a REALLY old copy of the book, because that's an errata we fixed a long time ago. If you just got this book I'd go back to the bookstore and ask for a newer printing - this one should have dust-binned over a year ago
Spot false dilemmas now, ask me how!
(If you're not on the edge, you're taking up too much room.)
I dug up an additional errata document that didn't make it on the Osborne page - sorry! As a temporary kludge I added it to the wickedlysmart site - I'm making a new thread called "Additional errata for the old K&B" with a link to these additional errata. Thanks for bringing this up!

Your welcome And thank you too for finding the additional errata.
my books, SCJP 1.4, seems to have 2003 copyright, so I guess it's not updated to the lates errata. I found some unexpected stuff after reading the first chapter and passing the first SELF Test. please post a valid link with the complete errata. I don't want to post stupid, old things.
thank you, silviu busu
