Wrong usage of class name in "The Stream API" section #184
Description
In the section Adding Intermediate Operations on a Stream, there is one wrong reference to a record class name.
Under the heading Flatmapping a Stream to Handle 1:p Relations, we assume two records: City and Country, whereas in the next sentence a different record State is mentioned which is supposed to be Country.
The State in the above screenshot has to be changed to Country. This section is not available in this repository and so I can't make a pull request fixing the issue.
