 Day 6 of Java Programming Journey 🚀 Today, I explored one of the most important topics in Java — Strings. Here’s what I learned: 🔹 A String is a collection (sequence) of characters. 🔹 It is a predefined class in Java, introduced in version 1.0. 🔹 The String class is final, which means it cannot be extended. 🔹 Strings in Java are immutable, meaning once created, their values cannot be changed. 🔹 There are two ways to create a String: 1️⃣ Using String Literals String name = "Java"; 2️⃣ Using the new keyword String name = new String("Java"); 10000 Coders #100DaysOfCode #LeetCode #Java #CodingJourney #ProblemSolving #Developer #Programming #LearnInPublic #Coding #10000Coders

🚀 Exploring Java Fundamentals with a Practical Twist! Just shared a simple yet powerful Java program that identifies numbers divisible by both 3 and 5 within a user-defined range. It’s a great example of how object-oriented design and basic control structures come together to solve real-world problems. 🔍 What it does: Prompts the user for a range Iterates through numbers from 0 to that range Prints numbers divisible by both 3 and 5 💡 Whether you're just starting out or brushing up on your Java skills, this snippet is a great reminder of how clarity and logic go hand in hand in programming. #Java #Programming #ObjectOrientedDesign #CodingJourney #TechLearning #LinkedInLearning #SoftwareDevelopment

💻 Exploring Patterns in Java! Today, I implemented a simple yet classic program — a Hollow Square Pattern using nested loops in Java. This program helps in understanding: ✅ The logic behind nested for-loops ✅ The use of conditional statements for pattern control ✅ How small programs improve logical thinking & coding structure Here’s the output for input 3: *** * * *** Every line of code brings a new learning opportunity. 🔥 #Java #Programming #PatternPrinting #DeveloperJourney #CodingPractice #LogicBuilding #LearnWithCode

🔹 The 4 Pillars of Object-Oriented Programming in Java Understanding the core principles of Object-Oriented Programming — Encapsulation, Inheritance, Polymorphism, and Abstraction — is essential for writing clean, reusable, and scalable code in Java. In this post, Otávio Borges breaks down each of these pillars with clear examples to help developers strengthen their object-oriented mindset. 💡 #Java #OOP #ObjectOrientedProgramming #JavaDevelopers #Programming #SoftwareDevelopment #Coding #LearnJava #BrasilJUG #DevsJava

🚀 Exploring the power behind Java! Every line of Java code begins with strong foundations — its keywords. From public, static, and void to interface and implements, each plays a vital role in defining Java’s robust object-oriented structure. #Java #Programming #Developers #Coding #Learning

I'm excited to share my comprehensive notes on Object-Oriented Programming (OOPs) in Java! ☕️ Abstraction, Encapsulation, Inheritance, Polymorphism... mastering these core principles is crucial for building robust and scalable applications. I've compiled the key concepts and practical examples in one place. Check it out and let me know your thoughts or favorite OOPs principle! 👇 #Java #OOPs #Programming #SoftwareDevelopment #CS #TechNotes #LearningJourney

🧡Today, I learned two important OOP (Object-Oriented Programming) concepts in Java — Method Overloading and Method Overriding. Method Overloading: When multiple methods have the same name but different parameters in the same class. void show(int a, int b); void show(String name); Method Overriding: When a child class redefines a method of its parent class with the same name and parameters. class Parent{ void display(){sout ("I'm Parent class");} } class Child extends Parent{ void display(){sout ("I'm Parent class");} } Overloading → Compile-time polymorphism Overriding → Runtime polymorphism #Java #OOPs #Programming #LearningJourney #CodeNewbie #100DaysOfCode #JavaDeveloper #LinkedInLearning

🚀 Exploring Abstraction in Java! Today, I practiced one of the key OOP concepts — Abstraction using an example program in Java. In this program, I created an abstract class Shape and implemented different subclasses like Square, Rectangle, and Circle, each providing its own logic for calculating the area. ✨ Key Concepts Covered: Abstract classes and methods Method overriding Dynamic method dispatch Code reusability and clarity through abstraction 🧠 Output: The program accepts input for each shape and displays the calculated area dynamically. Learning abstraction helped me understand how we can hide implementation details and focus only on essential functionalities. 💻 #Java #OOPs #Abstraction #LearningByCoding #ProgrammingJourney #CodePractice

🚀 Multithreading in Java using a Single run() Method In Java, Multithreading allows multiple parts of a program to run concurrently, helping us utilize CPU time efficiently and improve performance. A thread is a lightweight subprocess — the smallest unit of processing. We can create multithreading in Java using: Extending the Thread class Implementing the Runnable interface However, we can also handle multiple tasks using a single run() method by managing the logic of different threads inside it. 🔹 Example Concept: A single run() method can execute multiple parts of logic by checking the current thread’s name or priority — helping us control different thread operations in one place efficiently. 🔹 Key Points: Helps manage multiple operations within a single block of execution. Reduces code duplication and simplifies debugging. Efficiently demonstrates how one run() method can serve multiple threads. 👉 Main Use: To perform multiple tasks concurrently and make full use of CPU cores for better performance. 💡 Summary Multithreading = Better performance + Efficient CPU utilization + Parallel execution #Java #Multithreading #Thread #JavaDeveloper #Coding #Programming #TapAcademy #JavaLearning #Concurrency
