Today I Learned: Method Overloading in Java Today I explored one of the most important concepts in Java — Method Overloading. --> Method Overloading allows multiple methods in the same class with the same name but different parameters (type, number, or order). --> Key Points: --> JVM resolves overloaded methods using priority: Exact Match > Widening > Autoboxing > Varargs --> It is an example of Compile-Time Polymorphism --> Improves code readability and flexibility --> Changing only the return type is NOT valid overloading --> We can even overload main() and static methods #Java #Programming #Coding #Developer #100DaysOfCode #LearningJourney #Java #JavaProgramming #JavaDeveloper #SoftwareDevelopment #Programming #Coding #BackendDevelopment #TechLearning #Developers #LearnToCode #ProgrammingCommunity #100DaysOfCode #CodeNewbie #TechCareer #SoftwareEngineer

90% of your app uses Strings… but do you really know them? Today I spent some time understanding *Strings in Java*… and honestly, it’s deeper than it looks At first, I thought strings are just text we use in programs. But today I learned things like: * Strings are *immutable* (they can’t be changed once created) * Difference between *Heap Memory & String Pool (SCP)* * Why using equals() is important instead of == * And how small things can affect *performance & memory* It’s interesting how such a basic concept plays a huge role in real applications Still learning step by step… but enjoying the process If you’re learning Java too, what topic are you currently on? 👇 #Java #LearningJourney #Coding #Programming #BeginnerDeveloper #SoftwareDevelopment #100DaysOfCode

While revising Java Collections, I tried to simplify LinkedList in a visual way to make it easier to understand and remember. Here’s what I learned today, LinkedList uses a doubly linked list structure Each element is stored as a node (data + next + previous reference) It does not use continuous memory like arrays There is no fixed capacity, unlike ArrayList - When to use: Use LinkedList when your frequent operations involve insertions and deletions, as they are efficient. - When to avoid: It is not suitable when frequent retrieval (random access) is required, as it takes more time due to traversal. #Java #CollectionsFramework #LinkedList #JavaDeveloper #CodingJourney #LearnInPublic #SoftwareEngineering #Developers #Programming #TechLearning #DSA #BackendDevelopment

Mastering Java Method Overloading: How the Compiler Thinks Understanding method overloading goes beyond simply writing multiple methods with the same name; it involves grasping how the compiler determines which method to execute. This visual simplifies the resolution process into four key steps: - Method name and parameter count - Exact data type matching - Implicit type promotion when necessary Additionally, it highlights essential concepts such as compile-time polymorphism, early binding, and the occurrence of ambiguity errors. The takeaway? Each overloaded method possesses its own identity, and the compiler adheres to strict rules to select the best match. This is a crucial concept for every Java developer striving to write clean and efficient code! #TapAcademy #Java #Programming #MethodOverloading #Coding #JavaDeveloper #TechLearning #SoftwareDevelopment

Day 38-What I Learned In a Day (JAVA) Today I focused on number-based problem solving in Java and practiced 10+ problems to strengthen my logic building skills. Topics I covered: 🔹Finding the last digit 🔹Reducing a number to a single digit 🔹Checking Spy Number 🔹Counting digits in a number 🔹Checking Neon Number 🔹Calculating sum & product of digits 🔹Checking Armstrong Number 🔹Identifying Abundant Number 🔹Finding largest & smallest digit 🔹Checking Duck Number 🔹Printing odd digits 🔹Counting, sum, and product of odd digits This practice helped me improve: Looping concepts Conditional logic Number manipulation techniques Consistency in solving problems is helping me build strong fundamentals in Java. #Java #Programming #CodingPractice #ProblemSolving #LearningJourney

Day 38 of Learning Java Today, I explored how a class executes inside the JVM (Java Virtual Machine). Understanding this lifecycle really helped me see what happens behind the scenes when we run a Java program. 🔹 Class Loading   • The JVM loads the class into memory   • It brings the ".class" file into the system 🔹 Linking Phase  • Verification → Checks bytecode for errors  • Preparation → Allocates memory for static variables (default values like 0)  • Resolution → Replaces symbolic references with actual memory references 🔹 Initialization  • Static variables get their actual assigned values  • Static blocks are executed 🔹 Execution  • Methods start running and the program logic is executed 🔹 Destruction  • Objects are destroyed and memory is cleaned up by the Garbage Collector Static variables first get default values during preparation, and later their actual values during initialization. Thanks to my mentor Ashim Prem Mahto for the clear explanations and for always clearing my doubts. #Java #JVM #LearningJourney #Programming #SoftwareDevelopment #BackendDevelopment #CodingLife #JavaDeveloper #TechLearning #StudentLife
