In Java, the `equals()` method compares object references by default. To compare object values, override it with a custom implementation that returns true only when both objects have identical properties. This ensures correct equality checks in your code. #JavaTips

Java's `String` class uses an intern pool to store string literals, which means that if you create multiple strings with the same content, they will reference the same object in memory. This can have significant performance implications when working with large datasets. #JavaTips

Java tip: Use Optional to avoid null checks, but don’t overuse it in fields. Favor immutability, leverage records for DTOs, and keep methods small and focused. #JavaTips

Java tip: Prefer composition over inheritance, use Streams wisely (not everywhere), cache expensive calls, and always profile before optimizing. Clean code > clever code. #JavaTips

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

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
