How do thread-safe collections impact performance in Java?

How do thread-safe collections impact performance in Java?

Thread-safe collections ensure safe access in concurrent environments, but they can introduce overhead that affects performance.

What are some examples of thread-safe collections in Java?

Common examples include ConcurrentHashMap, CopyOnWriteArrayList, and BlockingQueue.

When should I use a thread-safe collection?

Use them when multiple threads need to read and write to a collection simultaneously without causing data corruption.

Are there any performance trade-offs I should be aware of?

Yes, while they provide safety, they can be slower than non-thread-safe collections due to synchronization overhead.
