In the OCPJP 8 certification topics, they have this under Java Collections:

- Search for data by using methods, such as findFirst(), findAny(), anyMatch(), allMatch(), and noneMatch()

There are no such methods in Collections though. Don't they mean in streams?

And then they also have this under the same header:

- Develop code that uses the merge(), flatMap(), and map() methods on Java Streams

But they have another header called Java Streams. That's just confusing.

Yes, they mean on Streams. I think they put collections because you often all list.stream() to get the stream. Still confusing though!
