What are the benefits of using immutable collections?

The benefits include thread safety, easier debugging, and improved performance in certain scenarios, as they can be shared without synchronization.

Can you give me an example of an immutable collection?

Sure! An example of an immutable collection is List.of() in Java, which creates an unmodifiable list.

Are there any downsides to using immutable collections?
