Java Streams: Next-Level Tricks for Clean and Powerful Code! 🚀

1️⃣ Merge Multiple Lists with flatMap() 🌊

Instead of nesting loops, flatten multiple lists into a single stream with flatMap().

List<String> list1 = List.of("Apple", "Banana");
List<String> list2 = List.of("Cherry", "Date");

List<String> mergedList = Stream.of(list1, list2)
    .flatMap(List::stream)
    .collect(Collectors.toList());
System.out.println(mergedList); // [Apple, Banana, Cherry, Date]

No need for manual iteration — just merge and go!
