ConcurrentHashMap utilizes a mechanism known as a thread probe to minimize contention among threads. When a thread adds an element to the map, it uses not only the key's hash but also a dedicated thread-specific probe value to select a bucket. This strategy helps distribute work across different buckets, reducing the likelihood of collisions. U ...
