🚀 Day 25 of my Java Learning — Set Hierarchy in Java 🌿 Hello everyone 👋 Yesterday I learned about Set in Java. Today I learned the Set hierarchy — how different Set interfaces and classes are connected in Java. The image shows the order like this: Set → SortedSet → NavigableSet → TreeSet Let’s understand this in simple words 👇 🧠 What it means? Set Used to store unique values (no duplicates)SortedSet A Set that stores values in sorted order NavigableSet A SortedSet that allows us to move to next, previous, higher, lower values TreeSet A real Java class that implements NavigableSet It stores unique + sorted values 🌍 Real Life Example Think about roll numbers of students: No duplicate roll numbers ✅ (Set) Roll numbers in sorted order ✅ (SortedSet / TreeSet) You can find next or previous roll number ✅ (NavigableSet) 💡 Easy Meaning TreeSet = Sorted + Unique values Learning collections step by step ✔️ Understanding Java feels easier when we see the hierarchy 😊 See you tomorrow with the next topic! 💪 #Java #Collections #SetHierarchy #TreeSet #NavigableSet #SortedSet #JavaLearning #30DaysChallenge #BeginnerFriendly

🎆🔥 Day 48 of My Java Learning Journey 🙌 Strings in Java -> More Than Just Text ☕ Ever wondered why Java Strings are so powerful yet so tricky? A String in Java isn’t just letters it’s a sequence of characters wrapped in a class that gives us superpowers like concatenation, comparison, and manipulation. 💭 Think of a String as a bracelet of characters each bead represents a letter, and once you make the bracelet (String), it’s hard to modify it directly because it’s immutable.  If you want to change it, you create a new bracelet (new String) instead! 🧠 Code Example: String name = "Yash"; String greeting = "Hello " + name; System.out.println(greeting); // Output: Hello Yash To modify repeatedly, use: StringBuilder sb = new StringBuilder("Java"); sb.append(" Rocks!"); System.out.println(sb); // Output: Java Rocks! 📘 Lesson: Strings are immutable that’s what makes Java efficient and secure. Every time you learn something small like this, your backend journey becomes stronger 💪. 🚀 Keep building, keep growing consistency turns learners into professionals! #Java #BackendDevelopment #StringInJava #CodingJourney #LearnInPublic #100DaysOfCode #JavaDeveloper #ProgrammersLife #CodeNewbie #SoftwareDevelopment #TechCareer #LearningNeverStops #Motivation #KeepLearning #CodeSmart #JavaBasics #CareerGrowth #DeveloperJourney #CodingCommunity #Consistency

👉 Day 26 of My Java Learning Journey 🥳 🚀 Exploring Multi-Dimensional Arrays in Java ☕ When I first learned arrays, I thought “Cool, I can store a list of items.” Then came multi-dimensional arrays, and it felt like unlocking another level in Java 🎮. A multi-dimensional array is basically an array of arrays. For example int[][] numbers = { {1, 2, 3}, {4, 5, 6} }; Here, it’s like a table rows and columns 📊. You can access any element using numbers[row][column]. So, numbers[1][2] gives 6. Yesterday, I was visualizing data in rows and columns for a project. That’s when I realized “Hey, this is just like using 2D arrays in Java!” It’s amazing how every small concept connects to real-world logic 🔄. Learning one concept at a time builds the foundation of a strong backend developer. Keep going, stay consistent, and your logic will evolve every day 🌱.. #Java #BackendDevelopment #Programming #CodingJourney #LearnInPublic #100DaysOfCode #JavaDeveloper #CodeNewbie #TechCareer #SoftwareDevelopment #DeveloperCommunity #CodeWithJava #ConsistencyIsKey #ProgrammersLife #BuildInPublic

 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

🚀 Learning by Doing — Java Conditional Statements in Action! 💻 Today, I practiced writing a simple Java program that checks grades based on marks using if-else conditions. This small project helped me understand how logical operators and condition checking work in real scenarios. ✨ Key takeaways: Improved understanding of if-else if structure Learned how to use logical operators (&&, <, >=) Enhanced code readability and logical thinking Every line of code written is a step toward becoming a better programmer! 💪 #Java #Coding #LearningInPublic #ProgrammingJourney #CodeNewbie #SoftwareDevelopment

Hey everyone! 👋 The second video in my new Tutorial playlist is live! So far, I’ve put together three playlists to help you learn Java step-by-step: 🎓 A Java beginners course with slides and ready-made code to get you started 💡 A Java tutorial series where I explain concepts in more detail and compare them 🛠️ A mini project playlist where I build fun projects like calculators that you can follow along with In this latest tutorial video, I’m covering inheritance and polymorphism, two super important concepts in Java. https://lnkd.in/dNbtWDCp Would love for you to check it out and let me know what you think! #Java #Learning #Coding #Tutorials #OOP

#DAY54 of Learning Java Fullstack... Today Let's learn about the inner classes.... What are the inner classes? 💡 Inner Classes in Java ★ An Inner Class in Java is a class defined inside another class. ★ It helps in grouping classes logically and improving encapsulation. ★Inner classes can access the private members of the outer class. 🔹 Types of Inner Classes in Java There are 4 main types of inner classes: ➤ Non-static Inner Class (Member Inner Class)  Defined inside another class but outside any method and without the static keyword. ➤ Static Nested Class Declared inside another class using the static keyword. It does not require an object of the outer class to be created. ➤ Local Inner Class Declared inside a method, constructor, or block. It is local to that block and cannot be accessed outside it. ➤ Anonymous Inner Class  A class without a name that is used to instantiate objects with certain modifications. #Java #InnerClasses #CoreJava #JavaProgramming #Coding #JavaDeveloper #ProgrammingConcept #LearnJava #CodeWithJava #TechLearning 10000 Coders Gurugubelli Vijaya Kumar

🚀 #Day53 of My Java Journey — Inheritance in Java Today, I learned about Inheritance, a core pillar of Object-Oriented Programming. 𝐈𝐧𝐡𝐞𝐫𝐢𝐭𝐚𝐧𝐜𝐞 allows a class (child) to acquire properties and behaviors from another class (parent). This helps in code reusability and reduces duplication. 👉In Java, inheritance is implemented using the extends keyword: 𝑬𝒙: class Child extends Parent { } This means Child class automatically gets access to all non-private members of the Parent class. 𝗧𝘆𝗽𝗲𝘀 𝗼𝗳 𝗜𝗻𝗵𝗲𝗿𝗶𝘁𝗮𝗻𝗰𝗲 𝗶𝗻 𝗝𝗮𝘃𝗮: 1) Single-Level Inheritance → One parent and one child class. 2) Multilevel Inheritance → Grandparent → Parent → Child (a chain of inheritance). 3) Hierarchical Inheritance → One parent class with multiple child classes. 4) Multiple Inheritance→ Not allowed with classes due to ambiguity (Diamond Problem). ✅ But it is possible with Interfaces. 5) Hybrid Inheritance → Combination of two or more types of inheritance. 𝙈𝙚𝙩𝙝𝙤𝙙 𝙊𝙫𝙚𝙧𝙧𝙞𝙙𝙞𝙣𝙜: A child class can change the implementation of a parent class method using @𝑶𝒗𝒆𝒓𝒓𝒊𝒅𝒆 annotation. 🔗𝘾𝙤𝙣𝙨𝙩𝙧𝙪𝙘𝙩𝙤𝙧 𝘾𝙝𝙖𝙞𝙣𝙞𝙣𝙜: When inheritance happens, constructors are called in order: If parent has default constructor, Java automatically calls super(). If parent has parameterized constructor, we must call super(args) manually. *️⃣𝒔𝒖𝒑𝒆𝒓() or 𝒕𝒉𝒊𝒔() must be the first statement in a constructor. 10000 Coders #Java #OOP #Inheritance #CodingJourney #LearningByDoing #JavaProgramming
