I just checked the Streams section in the objectives of the 1Z0-819 exam.

- Implement Functional Interfaces using Lambda Expressions, including interfaces from the java.util.function package
- Use Java Streams to filter, transform and process data
- Use Streams including Parallel streams  to perform decomposition and reduction, including grouping and partitioning

Will we need to memorise all the Stream API details - asking because there are quite a lot of operations with varying argument lists.
