Answer
It wraps a map and synchronizes all its method calls.
Collections.synchronizedMap wraps a standard map and synchronizes each method call, ensuring thread safety. However, this can become a bottleneck because it locks the entire map for each operation, limiting concurrency. In a scenario where multiple users are accessing a product catalog online, this can slow down the application as each access to the map must wait for others to complete.
