ConcurrentHashMap is designed for high concurrency, allowing multiple threads to read and write without locking the entire map.
How does it compare to HashMap in terms of speed?
While HashMap is faster for single-threaded operations, ConcurrentHashMap performs better in multi-threaded scenarios due to its segmented locking.
What are the trade-offs when using ConcurrentHashMap?
The trade-offs include slightly higher memory usage and complexity in implementation, but it provides better thread safety.
Can you give an example of when to use ConcurrentHashMap?
Use ConcurrentHashMap when you have a high volume of read and write operations from multiple threads, like in a web server.
