🚀 Java Revision Journey – Day 03 Continuing my Java revision, today I focused on Strings in Java, which play a major role in text processing and application development. 📌 Topics Covered: Strings ✔ Introduction to Java Strings ✔ Why Strings are Immutable ✔ String Concatenation ✔ Commonly Used String Methods String Handling Classes ✔ String Class ✔ StringBuffer Class ✔ StringBuilder Class ✔ Strings vs StringBuffer vs StringBuilder Understanding how Java handles strings helps in writing more efficient and optimized programs. Consistency in revisiting fundamentals helps build a stronger programming foundation. #Java #CoreJava #Programming #LearningJourney #BackendDevelopment #String #JavaDeveloper #Learning

#Day17 – Understanding Constructors in Java ⚙️ Today’s session helped me understand how constructors work in Java and how they are used while creating objects. Key Learnings: ✔ A Constructor is a special type of method whose name is the same as the class name ✔ Constructors do not have any return type, not even void ✔ Constructors are automatically called when an object is created using the new keyword ✔ If a programmer does not create any constructor, Java Compiler provides a Default Constructor ✔ Learned about Parameterized Constructors and Zero-Parameterized Constructors ✔ Understood Constructor Overloading (multiple constructors with same name but different parameters) ✔ Explored Constructor Chaining using this(), where one constructor calls another constructor within the same class TAP Academy Harshit T #Java #OOPS #CoreJava #Constructors #Programming #SoftwareDevelopment #LearningJourney #Consistency

🚀 Deep Diving into Java – Understanding Static Blocks & Execution Flow Practicing Java concepts today, focusing on static variables, static blocks, and method execution order. Seeing the output step-by-step in the command prompt really helps in understanding how Java loads classes and executes static members before main(). 💻 Practice makes concepts crystal clear. 📚 Consistency builds confidence. 🎯 Goal: Master core Java fundamentals. #Java #CoreJava #Programming #Learning #BackendDevelopment #CodingJourney #FSJD

Day 22-What I Learned In a Day(JAVA) Today I learned about method calling in Java. I practiced how a method can be called multiple times from the main() method. I also understood that when calling a method, we can pass arguments in two ways: 1️⃣ Directly passing values m1(10); 2️⃣ Passing values through a variable int a = 10; m1(a); Both approaches will pass the value to the method parameter and execute the method. Through this practice, I improved my understanding of method creation, parameter passing, and method execution flow in Java.

🚀 Day-11 Java – Understanding Pass By Value & Pass By Reference Today’s session helped me clearly understand one of the most important memory concepts in Java. 🔹 Primitive data types follow Pass By Value → Only the value is copied → Changes don’t affect the original variable 🔹 Objects work with References → Multiple references can point to the same object → Changes through one reference reflect everywhere Understanding how memory works internally makes a huge difference in writing bug-free and optimized code. This concept is foundational for: ✔ Object-Oriented Programming ✔ Collections Framework ✔ Advanced Java concepts Consistent practice is the key to mastering these fundamentals 💻🔥 #Java #CoreJava #OOPS #Programming #SoftwareDevelopment #LearningJourney #Day11 #JavaDeveloper #TechGrowth TAP Academy Harshit T Sharath R

🚀 Java Learning Journey — Day 6 Today I continued strengthening my Java fundamentals and explored an important concept: Static vs Instance behavior in Java. 🔹 Learned the difference between instance methods and static methods 🔹 Understood why static methods belong to the class, not the object 🔹 Explored static variables and how a single copy is shared across all objects 🔹 Studied how Java manages memory using Stack, Heap, and Method Area One key realization today: Static members are created when the class is loaded into the JVM, not when objects are created. This explains why all objects share the same static variable. Small concepts like these build the foundation for understanding how Java actually works internally. Looking forward to continuing tomorrow with Static Blocks and class loading behavior. #Java #LearningJourney #BackendDevelopment #Programming #SoftwareDevelopment #100DaysOfCode

Hello LinkedIn! Today I learned about Exception Handling in Java, which helps in handling runtime errors and keeping the program running smoothly. 📌 What I understood: ✅ What is an Exception ✅ Using try-catch blocks ✅ The finally block ✅ Types of Exceptions (Checked & Unchecked) ✅ Importance of handling errors in a program Exception handling helps developers write robust and reliable applications by preventing unexpected program crashes. Step by step, improving my Java fundamentals and programming skills 💻🔥 Consistency + Practice = Progress 🚀 #Java #Programming #ExceptionHandling #Coding #LearningJourney #Developer

Strengthening my understanding of Interfaces in Java as part of revising core Object-Oriented Programming concepts. Interfaces play a crucial role in achieving abstraction, standardization, and multiple inheritance in Java. Revisiting these fundamentals helps in writing cleaner, scalable, and maintainable code. Continuous learning and consistent revision are key to becoming a better developer. 💻📘 #Java #code #software

📌 **Core Java – Strings Concept** Explored the fundamentals of Strings in Java including immutability, String Constant Pool (SCP), and the difference between Heap and SCP memory. Also practiced string comparison using `==`, `equals()`, and `equalsIgnoreCase()` along with important methods like `substring()`, `indexOf()`, and `split()`. Understanding how Java handles strings internally helps in writing efficient and optimized programs.

⚙️ Java Interface vs Abstract Class This is one of the most important Java OOP concepts. Key differences: Interface: • Full abstraction • No constructor • Uses implements • Supports multiple inheritance Abstract Class: • Partial abstraction • Has constructor • Uses extends • Single inheritance Use Interface for contracts. Use Abstract Class for base classes. #Java #SoftwareEngineering #OOP #Programming
