Learned Do-While Loop in Java with User Input

🧠 Learning Update: Garbage Collection in Java I recently learned about Garbage Collection (GC) in Java and how it helps manage memory automatically. Garbage Collection reclaims memory used by objects that are no longer needed, ensuring efficient performance and preventing memory leaks. 💡 Key Phases of Garbage Collection: Mark Phase: The JVM identifies all active (reachable) objects in memory. Sweep Phase: It removes objects that are no longer referenced. Compact (Composition) Phase: The remaining objects are rearranged to eliminate memory fragmentation, creating a continuous memory space. Understanding these phases gave me a clear picture of how Java efficiently manages memory behind the scenes. #Java #GarbageCollection #JVM #Programming #SoftwareDevelopment #Learning

💡 Learning Update: Wildcard Types in Java I recently learned about Wildcard Types in Java Generics — a powerful feature that adds flexibility when working with generic classes and methods. Wildcards are represented by the ? symbol and allow code to handle different types more generically while maintaining type safety. 💡 Types of Wildcards: ? extends T → Upper-bounded wildcard (accepts T or any subclass of T) ? super T → Lower-bounded wildcard (accepts T or any superclass of T) ? (Unbounded) → Used when the type is unknown or doesn’t matter Example: List<? extends Number> numbers = new ArrayList<Integer>(); This allows a list of any subclass of Number, like Integer or Double. Understanding wildcard types helped me see how Java handles flexibility in generics while keeping type safety intact. #Java #Generics #Learning #Programming #SoftwareDevelopment #JVM

🔹 Topic: Exploring Collections in Java 💡 Learning Never Stops! Today, I started exploring one of the most powerful concepts in Java - Collections Framework. It provides a structured way to store, manage, and manipulate groups of objects efficiently. Overview from List, Set, and Map to advanced interfaces like Queue and Deque, each plays a key role in solving real-world problems with optimized performance and flexibility. Understanding Collections has not only improved my coding efficiency but also strengthened my problem-solving approach in Java. #Java #CollectionsFramework #ContinuousLearning #Coding #ProblemSolving #Programming #GrowthMindset #LearnEveryday

🚀 Today’s Java Learning Update! I explored how to generate random numbers in Java using the Random class from java.util. It was an interesting exercise — I wrote a program that keeps generating random numbers between 0 and 9 until it hits the number 5. Here’s what I learned: ✅ How to use Random rand = new Random(); ✅ How to generate random integers with rand.nextInt(10) ✅ How loops can control program flow based on conditions This small program helped me understand the power of randomness and loops in Java 💻 #Java #CodingJourney #LearningEveryday #Programming #RandomNumber #JavaDeveloper

💻 Learning Update: Generics in Java I recently learned about Generics in Java and how they make programs more flexible, reusable, and type-safe. Generics allow classes, interfaces, and methods to work with different data types while ensuring compile-time type checking — helping prevent errors and making code cleaner. 💡 Key points: Improves code reusability and type safety Eliminates the need for type casting Commonly used with collections like List, Set, and Map Example: List<String> names = new ArrayList<>(); names.add("Java"); names.add("Spring Boot"); This ensures the list only accepts String values — simple yet powerful! Understanding generics helped me appreciate how Java balances flexibility and safety in programming. #Java #Programming #SoftwareDevelopment #Learning #Generics #SpringBoot

💡 Did you know that in Java, the main() method doesn’t always execute first? Here’s a quick visual breakdown of what actually runs first 👇 🎯 Concept: Static Block vs Main Method 🧠 Designed by me — to make learning Java simpler! 👉 Check out my github account for entry level project ideas : https://lnkd.in/g46fXU98 #Java #Programming #Learning #CodeNewbie #AnkithaHV

🚀 Learning Java OOP: Class & Objects in Action Today, I explored Java Object-Oriented Programming (OOP) concepts implemented a simple program using: 1.classes 2.constructors 3.methods In this example, I created a Student class with attributes: 1.name 2.rollNo 3.marks. Using a constructor, I initialized each student's data, and a method mymethod() prints the student details. 💡 Key Takeaways: Class = blueprint for objects Object = instance of a class Constructor = initializes object data this keyword = refers to the current object Here’s a snippet of my code: [Student obj = new Student("Satish", 22, 654); obj.mymethod();] This program helped me solidify my understanding of OOP fundamentals in Java. #Java #OOP #Programming #Coding #Learning #DeveloperJourney

Day 8 of #50DaysOfCode – Java Today I practiced loops and conditional statements by writing a program to print all even numbers from 1 to 50. 💻 What I did: Used a for loop to iterate from 1 to 50 Checked each number using the modulus (%) operator Printed all even numbers 🧠 Concepts learned: Loops (for) Conditional statements (if) Modulus operator (%) Learning Java step by step! 💪 #Java #LearnInPublic #CodingJourney #Programming #50DaysOfCode
