What are some tips for ensuring thread safety in Java?

To ensure thread safety in Java, you can use synchronized blocks, locks, and concurrent collections. Would you like more details on any of these?

Can you explain how synchronized blocks work?

Synchronized blocks in Java allow only one thread to access a block of code at a time, preventing race conditions. You can synchronize on an object to control access.

What are concurrent collections?

Concurrent collections are thread-safe collections provided by Java, like ConcurrentHashMap and CopyOnWriteArrayList, which allow safe access by multiple threads.

How do I choose between using synchronized blocks and concurrent collections?

It depends on your use case. Use synchronized blocks for fine-grained control, while concurrent collections are easier to use for common scenarios.
