What are some examples of concurrent data structures in Java?
In Java, some examples of 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 map.
What is the difference between CopyOnWriteArrayList and ArrayList?
CopyOnWriteArrayList creates a new copy of the array on each write operation, making it thread-safe but less efficient for frequent writes compared to ArrayList.
When should I use BlockingQueue?
BlockingQueue is ideal for producer-consumer scenarios where you need to manage the flow of data between threads safely.
