Day 2 of my Java learning journey 💻☕ Today I explored how Java programs actually make decisions and perform operations. I learned about operators and control statements, which are essential for building program logic. Here’s what I learned today: 🔹 Arithmetic Operators – Performing calculations like addition, subtraction, multiplication, division, and modulus. 🔹 Relational Operators – Comparing values to check conditions. 🔹 Logical Operators – Combining multiple conditions in a program. 🔹 Assignment Operators – Updating and storing values in variables. I also practiced control statements that control how a program runs: 🔸 if–else statements for decision making 🔸 for loops for repeating tasks 🔸 while loops for running code based on conditions Through practice programs, I worked on building logic such as: Checking even or odd numbers Finding the greater number Generating multiplication tables Calculating factorials Using loops to repeat tasks Slowly understanding how programs think and make decisions. Every day I'm getting more comfortable with Java fundamentals. Looking forward to learning functions, arrays, and strings next. #Java #Day2 #LearningInPublic #ProgrammingJourney #Consistency

Day 26 of Learning Java ☕ Today, I practiced Access Modifiers in Java and learned how they help control the visibility of variables, methods, and classes. What I learned: • public – Accessible from anywhere • private – Accessible only within the same class • protected – Accessible within the same package or subclasses • default (no keyword) – Accessible only within the same package Why access modifiers are important: • They improve security • They help with data hiding • They make code more structured and maintainable #Java #JavaLearning #AccessModifiers #Programming #CodingJourney #LearnJava #DeveloperJourney #StudentLife

🚀 Day 24 of Learning Industry-Ready Java Full Stack Under the guidance of Hyder Abbas Sir, today I explored more concepts from the Java Collection Framework and learned how Java provides powerful utility methods to work with collections. 🔹 Topics I learned today: • Collections.shuffle() – Used to randomly shuffle the elements of a List. It helps in scenarios where random ordering of data is needed. • Collections.frequency() – Counts how many times a particular element appears in a collection. • Collections.sort() – Sorts elements in ascending order based on their natural ordering. • Comparable Interface – Used when a class itself defines its default sorting logic. Example: sorting objects by id, name, or marks inside the same class. • Comparator Interface – Used when we want custom or multiple sorting logic without modifying the original class. Example: sorting students by age, name, or marks depending on requirement. 📌 Key Learning: Understanding when to use Comparable vs Comparator is very important when working with objects in collections, especially in real-world Java applications. 💻 Practiced these concepts using ArrayList and different Collections utility methods to manipulate and sort data. Every day of learning is bringing me closer to becoming a better Java Full Stack Developer. #Java #JavaDeveloper #CollectionsFramework #LearningInPublic #FullStackDevelopment #Programming #SoftwareDevelopment

Day 3 of my Java learning journey 💻🚀 Today I explored one of the most important concepts in programming — Methods (Functions) in Java. Methods help in organizing code and making programs reusable and more structured. Here’s what I learned today: 🔹 What a method is and why it is used 🔹 How to create a method in Java 🔹 How to call a method from the main program 🔹 Understanding return values from methods I practiced writing programs such as: Finding the sum using a method Calculating factorial using a method Understanding how values are passed and returned in Java Learning how methods work really made me understand how real programs are structured. Slowly building strong fundamentals in Java step by step. Excited to move on to arrays tomorrow. #Java #Day3 #Programming #CodingJourney #LearningInPublic

📘 Day 30 of Learning Java – Scanner Class Today, I learned about the Scanner class in Java, which is used to take input from the user. 🔹 What is Scanner? Scanner is a predefined class in Java used to read input from different sources like keyboard input. 🔹 Package Information Scanner class is present in java.util package. String and System classes are present in java.lang package. java.lang is imported by default. But for Scanner, we must import: import java.util.Scanner; 🔹 System.in System.in is a standard input stream used to take input from the user. Example: Scanner sc = new Scanner(System.in); 🔹 Important Methods in Scanner Class ✔ To read integer → nextInt() ✔ To read short → nextShort() ✔ To read byte → nextByte() ✔ To read long → nextLong() ✔ To read float → nextFloat() ✔ To read double → nextDouble() ✔ To read boolean → nextBoolean() ✔ To read string (single word) → next() ✔ To read full line → nextLine() 💡 Today I clearly understood how Java handles user input and how different data types are read using different methods. Consistency is the key. Meghana M 10000 Coders Day 30 ✅ – Moving forward step by step. #Java #JavaLearning #Day30 #CodingJourney #Programming #DeveloperLife 🚀

📘 Day 6 Learning Java | Control Statements (Decision Making) Continuing my daily Java learning journey 🚀 Today, I focused on Decision Making Control Statements in Java, which help a program make choices based on conditions. ⚡ if statement – executes code when a condition is true ⚡ if–else statement – chooses between two blocks of code ⚡ else–if ladder – checks multiple conditions step by step ⚡ nested if – decision inside another decision ⚡ switch statement – selects execution paths based on values These concepts are essential for building logical flow in Java programs. Step by step, strengthening my Core Java fundamentals 💪 #Java #CoreJava #ControlStatements #DecisionMaking #IfElse #SwitchCase #JavaLearning #Day6

Day 1 – Learning Encapsulation (OOP-Revised) Today I revised about Encapsulation in Java. Encapsulation is a process of: • Packaging variables and methods into a single unit (class) • Protecting data by declaring them as private. In normal words encapsulation means we hide the data and only allow access through special methods like getters and setters. This helps: 1. keep data safe 2. avoid direct unwanted changes 3. make code more organized 4.reusability 5.code can modified without breaking the code It feels simple, but I realized this is one of the core foundations of Object-Oriented Programming.
