What is the `ConcurrentSkipListMap` used for in Java?
`ConcurrentSkipListMap` is a non-thread-safe map that maintains a sorted order of keys, similar to a regular `TreeMap`.
Thatâ€™s incorrect. `ConcurrentSkipListMap` is thread-safe and uses a skip list algorithm to maintain order and enable efficient concurrent operations.
Can you explain how `ConcurrentSkipListMap` ensures thread safety in a multithreaded environment?
