💡 Java tip: Avoid boxing overhead by using primitive streams. ❌ Creating Integer objects for each value: Stream&lt;Integer&gt; boxed = Stream.of(1, 2, 3, 4, 5); int sumBoxed = boxed.reduce(0, Integer::sum); #Java #JavaTips 🧵

Avoid @CrossOrigin("*") in production. It’s not a fix — it’s a vulnerability. Use proper CORS config with specific domains. #SpringBoot #WebSecurity #JavaTips #ayshriv

💡Java Tip : Prefer constructor injection over field injection. ❌ Field injection: @Component public class UserController { @Autowired private Logger logger; public void createUser(String username) { ... } } 🔴 Harder to test in insolation. #JavaTips

Java Streams confused? Stream - pipeline for processing data: → filter() → keep what you need → map() → transform values → reduce() → combine into one result Many values → process → result #Java #JavaStreams #JavaTips

Primary Key Basics: Use @Id to mark the primary key of your entity. Use @GeneratedValue(strategy = GenerationType.IDENTITY) to auto-generate it like an auto-increment column. #SpringDataJPA #JavaTips
