What are the best practices for using SynchronizedMap?

When using SynchronizedMap, it's important to ensure thread safety. Always synchronize access to the map.

Can you explain how to properly synchronize access?

You can use synchronized blocks or methods to wrap your access to the SynchronizedMap, ensuring that only one thread can modify it at a time.

Are there performance considerations I should be aware of?

Yes, while SynchronizedMap provides thread safety, it can lead to contention and performance bottlenecks. Consider using ConcurrentHashMap for better performance in high-concurrency scenarios.

What are the differences between SynchronizedMap and ConcurrentHashMap?

SynchronizedMap is a simple wrapper that synchronizes all access, while ConcurrentHashMap allows concurrent reads and updates without locking the entire map.
