The program compiles but without using "removeEldestEntry", I am not sure if it should be inheriting a size() from HashMap, or whether I need to implement one, and if so what it should contain.
Perhaps I also need a different constructor for the LinkedHashMap. I have searched the ranch and web I have not found a clear example.
I think it should get called automatically from the put method on line 21.
