Java: Concurrent Collections
Answer
It synchronizes access to a map to prevent thread interference.
Collections.synchronizedMap wraps a map to ensure that all access is synchronized, preventing thread interference. However, it can become a bottleneck, as the entire map is locked during each operation. For instance, in an e-commerce checkout, synchronizedMap ensures thread-safe access to a shared cart but may slow down under heavy load.
