Day 28 -What I Learned in a Day(JAVA) Today I started learning Looping Statements in Java. Loops are used to execute a block of code repeatedly until a certain condition becomes false. They help reduce code repetition and make programs more efficient. In Java, there are mainly three types of loops: • while loop • do-while loop • for loop Today I focused on the while loop. 🔹 What is a While Loop? A while loop executes a block of code repeatedly as long as the condition is true. The condition is checked before the loop executes, so if the condition is false initially, the loop will not run. Syntax of While Loop: initialization; while(condition) { // statements increment / decrement; } What I Practiced Today: ✔ Practiced 3 basic while loop programs ✔ Built a calculator program using while loop and switch statement ✔ Learned how loops control program flow and reduce repetitive code Every day I’m taking small steps to improve my Java programming skills and strengthen my understanding of core concepts.

📅 100 Days of Java – Day 1 🚀 Language: Java 🎯 Focus Topic: Scanner Input, If/Else, and Loops Today I started my 120 Days of Java challenge by focusing on the basics that every programmer must understand first — taking user input and controlling program flow. I explored how Java programs interact with users using the Scanner class. Instead of hardcoding values, the program can accept input at runtime, making it more dynamic and practical. I also practiced conditional statements (if / else) to allow the program to make decisions based on the input. This is one of the core building blocks of programming logic. Next, I worked with loops (for and while), which help automate repetitive tasks. Learning loops is important because they allow us to process multiple values or repeat operations efficiently. Through small programs, I applied these concepts to understand how logic flows step by step inside a program. This is just the beginning of my journey, but mastering the fundamentals is the key to writing better and more efficient programs in the future. 💬 Discussion: What is the difference between while loop and for loop? A for loop is usually used when the number of iterations is known beforehand, while a while loop is useful when the loop should run until a certain condition becomes false and the number of iterations is not fixed. #JavaProgramming #JavaDeveloper #JavaLearning #JavaJourney #120DaysOfJava #100DaysOfCode #CodingChallenge #DailyCoding #CodeEveryday #LearnInPublic #Programming #SoftwareDevelopment #DeveloperJourney #TechLearning #CodingLife #CodeNewbie #FutureDeveloper #ComputerScience #ProblemSolving #BuildInPublic #DeveloperCommunity #TechCommunity #StudentDeveloper #CodingPractice #ProgrammingLife #Developers #TechSkills #GrowthMindset #LearningJourney

🚀 Understanding Methods in Java In Java, a method is a block of code designed to perform a specific task. Methods help improve code reusability, readability, and maintainability. Instead of writing the same logic multiple times, we can simply call the method whenever needed. 🔹 Basic Syntax: returnType methodName(parameters) { // method body } 🔹 Types of Methods in Java ✔️ Methods with parameters ✔️ Methods without parameters ✔️ Methods with return value ✔️ Methods without return value Using methods effectively helps developers write cleaner and more modular code. 💡 Good programming is not about writing more code, it's about writing smarter code. #Java #Programming #Coding #SoftwareDevelopment #Learning #Developers

Today I Learned Operators in Java Understanding operators is essential for writing efficient and logical Java programs. Operators allow us to perform operations on variables and values, making them a core building block of programming. --> Types of Operators in Java 1. Arithmetic Operators Used for mathematical calculations Example: + - * / % 2. Relational Operators Used to compare two values and return a boolean result (true or false) Example: == != > < >= <= 3. Logical Operators Used to combine multiple conditions Example: && || ! 4. Assignment Operators Used to assign values to variables Example: = += -= *= /= %= 5. Unary Operators Operate on a single operand Example: ++ -- ! 6. Ternary Operator A shorthand form of the if-else statement Example: int max = (a > b) ? a : b; Key Takeaways --> Operators help perform computations and decision-making in programs --> Relational operators always return a boolean value --> The ternary operator simplifies conditional logic --> Understanding operators improves code readability and efficiency -->Currently strengthening my Java fundamentals as part of my learning journey in software development. #Java #JavaProgramming #LearnJava #JavaDeveloper #ProgrammingBasics #Coding #SoftwareDevelopment #Developers #TechLearning #CodeNewbie #JavaConcepts #ProgrammingJourney

🚀 Mastering Java Switch Statements – From Basic to Advanced I recently practiced different ways of using switch statements in Java, and here’s what I learned step-by-step 👇 🔹 1. Traditional Switch (Basic) ➡️ Used multiple case blocks with break statements ➡️ Works but repetitive and lengthy 🔹 2. Grouping Cases ➡️ Combined multiple cases using commas ➡️ Cleaner and reduces duplication 🔹 3. Switch with Arrow (->) ➡️ Introduced modern syntax ➡️ No need for break ➡️ More readable and concise 🔹 4. Using Variable for Output ➡️ Stored result in a variable ➡️ Better for structured and reusable code 🔹 5. Switch as Expression ➡️ Directly returns value ➡️ Makes code shorter and powerful 🔹 6. Using yield Keyword ➡️ Used in block-style switch expressions ➡️ Helps return values explicitly ➡️ Converted output to uppercase for better formatting ✨ Key Takeaways: ✔ Code readability improved step by step ✔ Reduced redundancy ✔ Learned modern Java features ✔ Understood difference between statement vs expression 🙏 Grateful for the Guidance: A special thanks to my mentor Anand Kumar Buddarapu sir for guiding me and encouraging me to explore Java pattern programming and logical coding techniques.

🚀 Day 25 of My Java Learning Journey Today I learned about the Object Class in Java and its important methods. 🔹 The Object class is the parent of all classes in Java. 🔹 toString() is used to convert an object into a readable string format. 🔹 clone() is used to create a copy of an object. 🔹 Java is not a purely object-oriented language because it uses primitive data types like int, char, and float. 🔹 Wrapper classes such as Integer, Double, and Character help convert primitive types into objects. Example: Employee e = new Employee(); System.out.println(e); Internally, Java calls: e.toString(); Every day I am improving my Java skills step by step 💪 Consistency + Practice = Growth 📈 #Java #ObjectOrientedProgramming #Programming #LearningJourney #100DaysOfCode #SoftwareDevelopment

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.

💡 Java Strings Decoded: Memory, Mutability & Logic Ever wondered what really happens when we create a String in Java? 🤔 Here’s a quick breakdown of the concept I explored today: 🔹 Strings are immutable – once created, their value cannot be changed. Any modification creates a new object. 🔹 String Constant Pool (SCP) helps optimize memory by storing only one copy of identical string literals. 🔹 Using new String("Java") creates a new object in the heap, even if the same value already exists in the pool. 🔹 == compares memory addresses, while .equals() compares the actual content of strings. Understanding how Java manages strings helps us write more efficient and optimized code.
