Recursion in Java: Base Case & Recursive Calls

Understanding the difference between shallow copy and deep copy in Java really changed how I think about object handling and memory. A shallow copy duplicates the reference — meaning changes in one object can unexpectedly affect another. On the other hand, a deep copy creates an entirely independent object with its own memory allocation. This concept might seem small at first, but it becomes critical when working with complex data structures, real-world applications, and avoiding unintended side effects. Key takeaway: Always be clear whether you're copying data or just references. #Java #Programming #Learning #DSA #SoftwareDevelopment

Day 34-What I Learned In a Day (JAVA) Today, I focused on pattern programming in Java, especially triangle patterns. I practiced different types of triangle patterns like: 🔹 Increasing triangle 🔹 Decreasing triangle 🔹 Right-aligned triangle 🔹 Reverse triangle Key Learnings: 🔹 Understanding how nested loops control rows and columns 🔹 Learning how to manage spaces and stars 🔹Breaking patterns into simple logic (increase & decrease) 🔹 Improving problem-solving and logical thinking Practiced 👇 #Java #Coding #PatternProgramming #LearningJourney #ProblemSolving

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

🚀 100 Days Java + DSA Challenge | Day 2 Today’s focus was on strengthening my programming fundamentals by covering: 🔹 Operators in Java (Arithmetic, Relational, Logical, Assignment) 🔹 Conditional Statements (if, if-else, nested if, switch) Understanding how operators work and how decisions are made in code is essential for building strong logic. These concepts are the backbone of problem-solving in Data Structures and Algorithms. 💡 Practiced writing multiple programs using conditions and improved my logical thinking step by step. Consistency is the key — small progress every day leads to big results. #100DaysOfCode #Java #DSA #LearningJourney #Coding #SoftwareDevelopment

💻 Practicing Binary to Decimal Conversion using Java Today I worked on converting a binary number into its decimal equivalent using logic and iteration. 🔍 Key Learnings: Understanding how binary digits map to powers of 2 Strengthening loop and mathematical logic Improving problem-solving skills step by step Instead of just memorizing, I focused on understanding the logic deeply and practicing with different inputs. 📌 Example: Binary: 1010 → Decimal: 10 Consistency + Practice = Progress 🚀 #Java #DSA #CodingJourney #Programming #100DaysOfCode #LearnToCode #ProblemSolving #DeveloperJourney #CodingPractice #TechSkills

#Day_13 of My Java Learning Journey – Writing Functions in Java Today I practiced how to create functions (methods) in Java, and I built a simple program to check whether a number is Even or Odd. 🔥 What I learned today: ✔ How to create a boolean function ✔ How to use if-else conditions inside a method ✔ How to return true/false ✔ How to call a method inside the main() function ✔ How to print the result in the console 🧩 Example I worked on: I created a method IfEven(int a) that: Prints whether the number is Even or Odd Returns a boolean value (true for even, false for odd) This helped me understand functions more clearly and how they improve code structure and reusability. #Java #LearningJourney #100DaysOfCode #Coding #Developer #JavaBeginners #OOP #CodeNewbie

Day 65 of #100DaysOfLeetCode 💻✅ Solved “Majority Frequency Group” problem in Java. Approach: • Created a frequency array of size 26 for all characters • Counted occurrences of each character in the string • For each unique frequency, counted how many characters share that frequency • Selected the frequency with the highest group size • In case of tie, chose the higher frequency • Built the result string with characters having the selected frequency Performance: ✓ Runtime: 5 ms (Beats 57.84% submissions) ✓ Memory: 44.51 MB (Beats 72.88% submissions) Key Learning: ✓ Practiced frequency grouping techniques ✓ Learned how to handle tie-breaking conditions ✓ Strengthened logic building with nested loops and conditions Learning one problem every single day 🚀 #Java #LeetCode #DSA #Strings #Hashing #ProblemSolving #CodingJourney #100DaysOfCode
