Stop writing loops for every collection. Use Java Streams. 🧵 ​Your future self (and your code reviewers) will thank you. ​#JavaTips #javaA

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 🥳 Mind blown �� #JavaTips #CodingLife #DevHack
