This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
A special constructor is provided to create a linked hash map whose order of iteration is the order in which its entries were last accessed, from least-recently accessed to most-recently (access-order). This kind of map is well-suited to building LRU caches.
Does LinkedHashSet also has the same facility ? According to Kathy and Bert's book they say that you can access elements by two ways in LinkedHashSet : one by insertion order and other by last accessorder . How can you use that ?
