Answer
It uses lock striping to minimize contention.
ConcurrentHashMap divides the map into segments, each independently locking only a part of the map, allowing multiple threads to operate on different segments concurrently. This minimizes contention and enhances throughput. Imagine processing orders in parallel, where different threads can update separate parts of the map without blocking each other.
