Answer 1

You may want to look into the LinkedHashMap or LinkedHashSet implementations in the Collections API, which provide support for a highly-configurable LRU framework.

Answer 2

LinkedHashMap would be perfect fit for this type of problems.removeEldestEntry() method of LinkedHashMap class returns true to remove oldest entry
