From Java 11 , Arrays.sort() uses TimSort internally. You don't need to write the TimSort algorithm yourself. This is a significant convenience. #JavaTips
Java's `Integer` cache: Between -128 and 127, Java caches Integer objects to improve performance. This means if you use a value within this range, it will return the same object instance each time. #JavaTips#PerformanceOptimization
Just realized you can do this in Java:
Map<String, List<String>> map = new HashMap<>();
map.put("fruits", new ArrayList<>());
map.get("fruits").add("apple");
map.get("fruits").add("banana");
map.values() = all your lists in one go 🥳
