This results in: [5, 4, 3, 2, 1] Conclusion In this short guide, we've taken a look at how you can collect and reverse a stream/list in Java 8, using collect() and Collections.reverse() - individually, and together through the collectingAndThen() method. # java# streams Last ...

In the above example, we first created aStreamof string and then collect the elements into aLinkedList. Since theLinkedListis a double-linked data structure in Java, we can iterate it in any direction: forward and backward. We preferred to loop over theLinkedListobject in the reverse direction...
