#Day_03 #Libraries: A library is a set of re-usable functionalities, and every programming language has built-in libraries to it like Header Files in C & CPP Languages and Packages in Java Language same as that .NET Languages are also provided with built-in libraries and we call them “FCL (Framework Class Libraries)” in .NET Framework and “CORE FX” in .NET Core and .NET.

n JavaScript, what will happen if you send an object directly as body in a fetch() POST request without using JSON.stringify() and without setting "Content-Type": "application/json"?

Python is the only language you won’t find programmers hating. The reason is simple: it’s very powerful without unnecessary noise like in Java or the headaches of Node.js. It runs fast and smoothly even when I’m using just a Linux Live system. Java with Spring Boot feels like a turtle, and Node.js needs four libraries for the simplest project in Express.js and node modules 260 megabit for project 4 kelobit. #Python #Programming #Developers #CodingLife #SoftwareEngineering #Java #NodeJS #SpringBoot #ExpressJS #Linux #TechThoughts

🚀 Day 24 – Core Java Learning Journey Today’s session was a reality check and a deep dive into advanced String concepts. 🔹 Understood the difference between Immutable and Mutable Strings 🔹 Explored StringBuffer vs StringBuilder and their internal working 🔹 Learned about default capacity (16), dynamic resizing formula, and memory optimization using trimToSize() 🔹 Practiced methods like append(), delete(), length(), capacity() 🔹 Explored StringTokenizer and understood why split() is preferred in modern Java 🔹 Gained clarity on thread safety difference between StringBuffer and StringBuilder More importantly, today emphasized consistency, IDE practice (Eclipse usage), and interview readiness. Preparing step-by-step towards mastering Object-Oriented Programming next 🚀 #CoreJava #JavaLearning #SoftwareDevelopment #PlacementPreparation #Consistency

I used to think equals() and == in Java were basically the same. They’re not. == checks if two references point to the same memory location. equals() checks if two objects are logically equal. That difference looks small. Until your HashMap stops working properly. In Java, if you override equals(), you must also override hashCode(). Because collections like HashMap use hashCode() first to find the bucket, and then equals() to confirm the match. Forget one of them… and your object becomes “invisible” inside the map. One small contract. One big lesson. #Java #BackendDevelopment #SoftwareEngineering #Programming
