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

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

Want clean REST APIs in Java? Use: - @RestController - @RequestBody - @PathVariable - @ResponseStatus Spring REST keeps your code lean and expressive. #JavaTips #SpringREST #ayshriv

Version your REST APIs like this: /api/v1/users instead of /api/users It helps in future changes without breaking old code. #APIDesign #SpringBoot #JavaTips #ayshriv

💡 Java tip: Starting from Java 11, if you need to repeat n times a specific string, you can use the String method repeat(n). ✅ Example: String result = "$".repeat(10); System.out.println(result); // $$$$$$$$$$ #Java #JavaTips

Use CascadeType.REMOVE with care! It deletes child entities when the parent is deleted. Deleting a post deletes all comments too #JavaTips #SpringBoot #ayshriv

🚀 Java Developers, let's talk about Garbage Collection! 🗑️💡 Ever wondered how Java automatically manages memory & prevents leaks? 🧵👇 #Java #Coding #GarbageCollection

2️⃣ How does it work? Objects in Java become eligible for GC when they have no active references. The GC sweeps them away, freeing up memory! 🔥 💡 Ways to make an object eligible for GC: ✅ Assign null → obj = null; ✅ Reassign reference → obj1 = obj2; #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

Custom login page in Spring Security? Just override the formLogin() in your security http.formLogin().loginPage("/custom-login"); And don’t forget to permit it: http.authorizeRequests().antMatchers("/custom-login").permitAll(); #JavaTips #springboot #ayshriv

💡Java: If you have to read small files, you can use Files.readAllLines(), it's more direct and simple. #JavaTips

💡 Java tip: Use Duration and Instant for precise time calculations. ✅Instant represents a point in time in UTC, with nanosecond precision. Can be obtained by #Java #JavaTips 🧵

💡Java tip: Since Java 15 you can write multiline strings more easily with 'Text Blocks'. ✅ Writing JSON content with a text block: String json = """ { "name": "John", "age": 30 } """; ✅ No escape characters ✅ No '+' signs ✅ Easy indentation #JavaTips

Classic switch in Java allows fall-through when break is missing. Enhanced switch (Java 14+) fixes this with concise, safer syntax using arrows and direct value returns. Modern switch makes Java code cleaner and easier to maintain. #Java #Programming #JavaTips #CleanCode

Java tip of the day: Always use error handling to catch and resolve errors in your code. #JavaTips #programming

From Java 11 , Arrays.sort() uses TimSort internally. You don't need to write the TimSort algorithm yourself. This is a significant convenience. #JavaTips

Dependency Injection is your best friend! Never use new in your classes. Let Spring manage your beans. Use @Autowired or constructor injection #SpringBoot #JavaTips #CleanCode #ayshriv
