🚀 Day 3 – Learning Java Basics Step by Step Today was all about strengthening my basics in Java, and I really enjoyed revising the core concepts. I started again with variables and understood how they are used to store data in a program. It became clearer how values are assigned and used in different expressions. I also learned the difference between variables and literals, which helped me understand how calculations actually work in code. One interesting part was understanding how memory works in Java. I got a basic idea of how variables store values inside memory, which made me feel more connected to how programs run internally. After that, I focused on data types. I learned about primitive data types like int, float, double, char, and boolean, and also about non-primitive types like String, Array, Class, and Object. Knowing their sizes and uses made it easier to understand which data type to use in different situations. I also practiced a simple program to find the sum of two numbers. It was a small task, but it helped me understand how to write and execute a Java program step by step. Along with that, I learned about comments in Java, which are helpful for explaining code and making it more readable. The most useful part of today’s learning was taking input from the user using the Scanner class. It made my programs more interactive and interesting. Overall, I feel more confident than before. Step by step, I am improving my coding skills and understanding Java better. 💪 I will stay consistent and keep practicing every day. #Java #DSA #CodingJourney #Learning #Consistency

📘 Day 5 of Java Learning Series 🔍 Operators in Java Operators are symbols used to perform operations on variables and values. 🔹 1. Arithmetic Operators ✔ + (Addition) ✔ - (Subtraction) ✔ * (Multiplication) ✔ / (Division) ✔ % (Modulus) 🔹 2. Relational (Comparison) Operators ✔ == (Equal to) ✔ != (Not equal) ✔ > (Greater than) ✔ < (Less than) ✔ >= , <= 🔹 3. Logical Operators ✔ && (AND) ✔ || (OR) ✔ ! (NOT) 🔹 4. Assignment Operators ✔ = , += , -= , *= , /= 💡 Example: int a = 10, b = 5; System.out.println(a + b); // 15 System.out.println(a > b); // true System.out.println(a == b); // false 📌 Key Point: Operators help perform calculations and make decisions in programs. 👉 Follow me for more Java content 🚀 #Java #CoreJava #Programming #Developers #100DaysOfCode #Coding

🚀 Day 8 – Understanding Functions and Parameters in Java Today, I learned about functions (methods) in Java, which are very important for writing clean and reusable code. A function is simply a block of code that performs a specific task and can be used multiple times in a program. This helps to reduce repetition and makes the code easier to understand. I started by learning the basic syntax of a function, where we define a return type, function name, and body. Then I moved to functions with parameters, where values are passed into the function to perform operations. This made the concept more practical. Next, I learned about types of parameters: Formal Parameters: These are variables defined in the function. Actual Parameters: These are the values passed when calling the function. 👉 Understanding this difference made it clear how data flows inside a program. Overall, today’s learning helped me understand how to write better and more structured code using functions. 💪 I will keep practicing daily and improve step by step in my coding journey. #Java #Coding #DSA #Learning #Consistency

🚀 Starting My Java Learning Journey – Day 16 🔹 Topic: Encapsulation in Java. Encapsulation is one of the core OOP concepts. It is the process of wrapping data (variables) and code (methods) into a single unit (class). It also helps in data hiding. 📌 How to Achieve Encapsulation? ✔ Declare variables as private. ✔ Provide public getter and setter methods to access and update values. 📌 Example Program class Student { private String name; // Getter method public String getName() { return name; } // Setter method public void setName(String name) { this.name = name; } } public class Main { public static void main(String[] args) { Student s1 = new Student(); s1.setName("John"); System.out.println(s1.getName()); } } Output: John 💡 Key Points: ✔ Protects data from unauthorized access. ✔ Improves security and flexibility. ✔ Achieved using private variables + getters/setters. #Java#JavaLearning #Programming #BackendDevelopment #CodingJourney #Encapsulation #OOP#

Day – Java Learning Update Today I learned about Multiple Inheritance and Hybrid Inheritance in Java. Multiple Inheritance means one class inherits from more than one class Hybrid Inheritance is a combination of two or more types of inheritance But Java does not support multiple and hybrid inheritance using classes Reason → Diamond Problem When two parent classes have the same method Child class gets confused which method to inherit This creates ambiguity Example flow: A → B A → C B + C → D Now D gets same method from B and C → confusion Solution in Java: Java avoids this problem by not allowing multiple inheritance with classes Instead, Java uses interfaces Interfaces provide multiple inheritance without ambiguity Key takeaway: Java focuses on simplicity and avoids confusion in method resolution #Java #JavaFullstack #OOPS #Inheritance #BackendDeveloper #LearningJourney #Programming 10000 Coders Meghana M
