When we need to merge more than 2 Streams, things become a bit more complex. One possibility is to concatenate the first two streams, then concatenate the result with the next one and so on. The next code snippet shows this in action: @Test public void given3Streams_whenMerged_thenResult...
Tip: There are more ways to merge lists using libraries like guava or Apache commons lang, but they all useaddAll()method only. So it’s better to use this method directly. 1.2. UsingStream.flatMap() Java 8 streams provide us with one-line solutions to most of the problems and at th...
