Removing the “first” object from a Set

Question

Under certain situations, I need to evict the oldest element in a Java Set. The set is implemented using a LinkedHashSet, which makes this simple: just get rid of t

Answer 1

if (!mySet.isEmpty())
  mySet.remove(mySet.iterator.next());

seems to be less than 3 lines.

You have to synchronize around it of course if your set is shared by multiple threads.
