如何获取ConcurrentHashMap的tailMap？

Question

I am using TreeMap to get tailMap , but its causing concurrency issues. So I decided to use ConcurrentHashMap instead. How do I get tailMap for ConcurrentHashMap ?

There isn't any API like map.tailMap(key) for ConcurrentHashMap .

Thanks

Answer 1

That method is defined in the interface SortedMap , so you need to use a map that implements that interface. The likely concurrent candidate is ConcurrentSkipListMap .
