What are some famous concurrent data structures?
Some famous concurrent data structures include ConcurrentHashMap, CopyOnWriteArrayList, and BlockingQueue.
Can you explain how ConcurrentHashMap works?
ConcurrentHashMap allows concurrent access by dividing the map into segments, enabling multiple threads to read and write without locking the entire structure.
What are the advantages of using CopyOnWriteArrayList?
CopyOnWriteArrayList is great for scenarios with more reads than writes, as it provides thread-safe iteration without locking.
Are there any downsides to using these structures?
Yes, while they improve concurrency, they can have higher memory overhead and may not be suitable for all use cases.
