How can I ensure thread safety in Java collections?

How can I ensure thread safety in Java collections?

You can ensure thread safety in Java collections by using synchronized collections or concurrent collections from the java.util.concurrent package.

What are some examples of concurrent collections?

Some examples include CopyOnWriteArrayList, ConcurrentHashMap, and BlockingQueue.

When should I use synchronized collections instead of concurrent ones?

Use synchronized collections for simpler use cases with fewer threads, while concurrent collections are better for high concurrency.

Can you explain how ConcurrentHashMap works?

ConcurrentHashMap allows concurrent access by dividing the map into segments, locking only the segments being modified.
