Clean Code for Maintainable Tests with RestAssured in Java

📢 Stop writing messy Lambdas ❗ When I first started with Java 8, I thought Lambda expressions were the ultimate "clean code" hack. Then I discovered Method References, and it changed the game. If your code looks like this: list.forEach(s -> System.out.println(s)); It could look like this: list.forEach(System.out::println); It’s cleaner, more readable, and honestly? It just looks more professional. I’ve put together a quick 7-slide guide to the 4 types of Method References you need to know for your next MNC interview (and for your daily PRs!): 1️⃣ Static Methods (Integer::parseInt) 2️⃣ Instance Methods of a Particular Object (System.out::println) 3️⃣ Instance Methods of an Arbitrary Object (String::toLowerCase) 4️⃣ Constructor References (ArrayList::new) Mastering these is a small change that makes a huge difference in how your "Java Full-Stack" skills are perceived. Which one do you find yourself using the most? Let’s discuss in the comments! #Java8 #CleanCode #BackendDeveloper #FullStack #ProgrammingTips #JavaDeveloper #CodingLife #SoftwareEngineering

Day 20-What I Learned In a Day(JAVA) What is Method? A method is a block of code that performs a specific task. It is used to improve code reusability, readability, and modularity. Syntax: accessModifierreturnTypemethodName(parameters) { // method body } Important Terminologies: 1️⃣ Method Signature Method name + parameter list only. Example: add(int, int) (It does NOT include return type.) 2️⃣ Method Declaration Return type + method name + parameters (without body). Example: public int add(int a, int b); 3️⃣ Method Definition Complete method including body (implementation). Example: public int add(int a, int b) { return a + b; }  Practice Done Today ✔ Created methods for addition, subtraction, multiplication,Division ✔ Understood static and non-static methods ✔ Practiced method calling ✔ Practiced dynamic input using Scanner Practiced 👇 #Java #CoreJava #JavaMethods #MethodSignature #MethodDeclaration #MethodDefinition #StaticVsNonStatic #OOPSConcepts #JavaBasics #CodingPractice #LearningJourney

Day 39: The Decision Makers – Mastering Java Conditional Statements 🛣️🧠 Today was all about "Branching." I moved from linear code to dynamic logic. I learned that Conditional Statements are the heart of every "Smart" feature in a professional application—from checking login credentials to calculating dynamic discounts. Here is the "Logic Ladder" I climbed today: 1. Simple if (The One-Way Gate) 🚪 The most basic decision. If the condition is true, the code runs. If not, it skips it entirely. ▫️ Use Case: Sending a notification only if a user has unread messages. ▫️ Syntax: if (balance < 0) { System.out.println("Low Balance!"); } 2. if-else (The Two-Way Fork) 🍴 The "Plan B" statement. It ensures that something always happens, whether the condition is met or not. ▫️ Use Case: If passwordMatch is true, log in; else, show an error. ▫️ Logic: It’s an "Either/Or" scenario. 3. if-else-if Ladder (The Multi-Choice) 📶 This is for complex, multi-layered decisions. Java checks each condition one by one until it finds a "True" match. ▫️ Use Case: Grading systems (A, B, C, D) or calculating tax brackets based on income. ▫️ Efficiency: As soon as one condition is met, Java skips the rest of the ladder! I realized that every condition inside the parentheses () must result in a boolean (true or false). This is where the Relational and Logical operators I learned earlier (like &&, ||, ==) finally come to life! Code isn't just about calculation; it's about Navigation. Today, I learned how to give my program a "Brain" to choose the right path.

I wrote 50 lines of code to do something that takes 4. Not because I was lazy. Because I didn't know there was a better way. Java Streams changed that. Before: → Loop → Check → Update → Return After: → .filter() → .map() → .collect() → Done. Same result. Half the code. Easier to read at 11pm. Spend 30% reading the API. Spend 70% writing the code. That's the ratio that builds real skill. Save this. Open your IDE. Find one loop. Convert it. That's your first rep. #JavaDeveloper #SoftwareEngineering #CleanCode

Why Doesn’t Rollback Happen in Self-Invocation with @Transactional? You annotate a method with @Transactional. An exception occurs. You expect a rollback. But the data is still committed. If this happens in Spring Framework, one common reason is self-invocation. What Is Self-Invocation? Self-invocation happens when a method inside a class calls another method of the same class. At first glance, this seems perfectly fine. But here’s the hidden problem. Why Rollback Doesn’t Happen: Spring applies @Transactional using a proxy mechanism. -When a method is called from outside the class, the call goes through Spring’s proxy. -The proxy starts the transaction and manages rollback. However, when a method calls another method inside the same class: -The call happens directly within the object. -It bypasses Spring’s proxy. -Spring never intercepts the call. -The transaction is never started. And if no transaction was started, rollback cannot happen. The Real Reason: Rollback doesn’t fail because of the exception. Rollback fails because Spring never got the chance to manage that internal method call. No proxy interception → No transaction → No rollback. Key Takeaway: @Transactional is not just an annotation. It works only when the method call goes through Spring’s proxy. #Java #SpringBoot #SpringFramework #BackendDevelopment #SoftwareEngineering #Microservices #AOP #Transactional

🚀Understanding @#Autowired in #SpringFramework Today I learned about @Autowired in the Spring Framework. 🔎 @Autowired is used for automatic dependency injection. It tells the Spring Container to automatically inject the required bean. Instead of creating objects manually using new, Spring automatically connects the required dependencies. 📌 Example: @Component public class StudentService { @Autowired private StudentRepository repository; } This helps reduce boilerplate code and makes applications loosely coupled. #SpringFramework #Java #BackendDevelopment #SpringBoot #LearningJourney 10000 Coders Understanding @Autowired Annotation Content: Automatic Dependency Injection Spring injects required beans automatically Reduces manual object creation

Debugging in Java builds problem solvers, not just programmers. Writing code is just the beginning. The real learning starts when something breaks. ✅ When you debug, you learn: ~ How the JVM actually behaves ~ How memory, threads, and exceptions work ~ How different layers of an application connect ➡️ Every bug you solve improves your thinking, patience, and system understanding. Great developers aren’t the ones who write the code. They’re the ones who know how to fix broken systems. #Java #Debugging #SoftwareDevelopment #BackendDeveloper #SpringBoot #CodingJourney
