Overcame Spring Boot setup challenges with Faisal Memon's tutorial

The Power of Dependency Injection in Spring Boot One of the core pillars that makes Spring Boot so powerful is Dependency Injection (DI). Instead of manually creating objects with new, we let Spring handle that for us. It automatically creates, manages, and injects the required components — keeping the code organized, scalable, and easy to test. 💡 This reduces coupling between classes, improves maintainability, and makes the code much cleaner and more flexible. No new. No tight coupling. Just clean, automatic dependency injection ✨ 🔁 Once we understand how Spring manages our objects (beans), we realize how Inversion of Control truly changes the game in modern backend development. #Java #SpringBoot #Backend #SoftwareDevelopment #Programming #learning #creating

Me a few weeks ago: “I’ll never understand OOP. It’s just too confusing.” Me today: “Wait… inheritance isn’t always the answer. Sometimes, composition actually makes more sense.” Honestly, this did not happen overnight. I spent days trying to understand how all these concepts fit together encapsulation, inheritance, composition, interfaces, polymorphism and when to use what. I started coding small examples for each one. Most of them broke at first 😅 but with every error, things started to make a little more sense. I have now organized all those practice files topic wise and uploaded them to github. It’s not perfect, but it feels good to look back and see progress. 🔗 https://lnkd.in/dkqaDdbC #Java #OOP #GitHub #LearningJourney #KeepLearning #Programming

🚀 Day 57 of My LeetCode Journey 🚀 🔹 Today I solved Longest Common Prefix. Key Idea: To find the longest common prefix in a list of strings, we assume the first string as the prefix and gradually shrink it while checking with every other string. The moment a string doesn't start with the prefix, we trim the prefix until it matches — or becomes empty. 💡 What I learned: String operations like startsWith() can simplify logic. Sometimes, a simple greedy shrinking approach performs better than overthinking the solution. Clean code > complex code. 🧠 Takeaway: Break the problem into smaller checks. Don’t force complexity when simplicity solves it efficiently. Here’s the mindset: ➡️ Small progress every day still counts as progress. ➡️ Consistency beats intensity. #100DaysOfCode #leetcode #codingjourney #java #programming #learning

🧩 I still remember when my Spring Boot API refused to return JSON… I spent hours debugging, only to realize I used the wrong annotation. 😅 That day, I finally understood the difference between 👉 @Controller and @RestController And trust me — this tiny detail can make a big difference. So I turned that learning into a simple visual guide 👇 💡 In this carousel, you’ll learn: ✅ What each annotation actually does ✅ When to use one over the other ✅ And… the BIG question — 👉 What happens if you use both together? Hint: one silently wins the battle 👀 💬 Drop your guess in the comments! And share this if it helped you or your team avoid that “why is my JSON not returning?” moment 😅 #SpringBoot #Java #BackendDevelopment #Microservices #CodeTips #SoftwareEngineering #Developers #LearningInPublic #TechCommunity #Programming #CareerInTech #RestAPI

🚀 Week 4 of My Java Learning Journey! This week, I explored Methods and Arrays — the building blocks that make Java programs modular and data-driven! 🧠 It was exciting to understand how methods simplify code and how arrays efficiently store and manipulate data. 💻 🧩 Key Learnings: Methods: Definition, Parameters, Scope Static methods and why they’re important Calling and Returning Methods Arrays: One-Dimensional & Two-Dimensional Array operations: Sorting and Searching 💻 Practice Programs: Array operations: Find Max, Min, Reverse, Sum Menu-based Array Application Method-based problem solving and modular programs 📝 Extra Skill: Improved code organization and reusability using methods 🔗 Check out my Week 4 GitHub repo: https://lnkd.in/gPAqMUPf Excited for Week 5, where I’ll dive into String Concepts — taking Java to the next level! 🚀 #Java #Programming #CodingJourney #Git #GitHub #100DaysOfCode #Learning #Backend

Java for Newbies #4 — Constructor: Building the Object Every object in Java is born through a constructor — yet most developers never really stop to ask what happens when we call new. In this session, I break down how a constructor actually builds the object — from memory allocation to initialization — and why it’s much more than just a “method without a return type.” If you’re learning Java seriously, this one is essential. -Watch the full lecture on YouTube https://lnkd.in/gSNRmess -The detailed blog is already published — no need to make notes, it’s all there. ♻ Repost to help others for learning. 👤 Follow me for more.

🚀 Week 3 of My Java Learning Journey! This week, I explored one of the most exciting and essential parts of Java — Control Flow and Loops! 🧠 It’s been amazing to see how logic and structure come together to make programs dynamic and powerful. 💻 🧩 Key Learnings: Conditional statements: if, if-else, else-if, switch Loops: for, while, do-while Control statements: break, continue Nested loops 💻 Practice Programs: for loop: Factorial, Multiplication Table switch case: Calculator, Day of Week while loop: Reverse Number, Sum of Digits if-else: Eligible for Vote, Grade Calculator …and many more! 🚀 📝 Extra Skill: Started solving Java logic problems on HackerRank to strengthen my problem-solving skills 💪 🔗 Check out my Week 3 GitHub repo: https://lnkd.in/gzvSXY8h Excited for Week 4, where I’ll dive into Methods and Arrays — bringing structure and data manipulation to the next level! 🎯 #Java #Programming #CodingJourney #Git #GitHub #100DaysOfCode #Learning #Backend #HackerRank Would you like me to make a Week 4 template now (similar tone and layout) so you can just fill it in next week?

🎯 Java Bootcamp – Day 3 Highlights 💡 Object-Oriented Programming (OOP) Unlocked! Today’s session was a deep dive into the world of OOP — the secret sauce behind clean, scalable, and real-world Java applications. Here's what I tackled: 🧱 OOP Foundations 🔹 Class = Blueprint | Object = Real-world instance 🔹 Why OOP? Because modular, reusable code is the future! 🛠️ Constructors & Methods 🔹 Used constructors to auto-initialize object data 🔹 Built methods that do things and return results (like calculating interest!) 🧯 Error Handling 101 🔹 Explored try-catch to gracefully handle runtime errors 🔹 No more crashes — just clean, safe execution! 💰 Hands-On Project: BankAccount App 🔹 Built a class with deposit(), withdraw(), and displayBalance() 🔹 Added error checks for smoother user experience 🔹 Practiced real-world logic with clean OOP structure Each concept added a new layer to my Java mindset. Can’t wait to keep building smarter and cleaner code as the bootcamp continues! 💻🔥 #JavaBootcamp #Day3 #OOPinJava #LetsUpgrade #TechJourney #StudentDeveloper #ParulUniversity #100DaysOfCode #CodeWithPraneel #BuildInPublic
