Java Streams Intermediate Operations filter() & flatMap()

This video describes the Java Streams filter() and flatMap() intermediate operations. which are both stateless and run-to-completion operations. We also discuss a curiouslimitation with flatMap() that makes it ineffective for parallel streams, as well as a remedy for this problem.

Very simple explanation of flatMap :

flatMap takes a function as parameter, that function creates a stream from every element previous stream and then flatMap concatenate these streams in one big stream. That’s it 🤷‍♂️
