📘 Day 30 | Core Java Series The Collections Framework is where Core Java concepts meet real-world programming. This visual explains the basics: 👉 List 👉 Set 👉 Map Remember this: List → Order matters Set → Uniqueness matters Map → Key–Value matters This marks the end of my Core Java learning series.

📘 Day 29 | Core Java Series Exception Handling helps Java programs deal with runtime errors gracefully. This visual explains the basics: 👉 try 👉 catch 👉 finally Remember this: try → risky code catch → handle error finally → always executes Understanding this prevents program crashes and improves reliability. 📌 Save this for revision 💬 Feedback is welcome #Java #CoreJava #ExceptionHandling #LearningInPublic #Programming

🔷 Abstract Class in Java – Strengthening OOP Foundations While revisiting Core Java concepts, I explored the importance of Abstract Classes in Object-Oriented Programming. An abstract class: • Cannot be instantiated • Can contain both abstract and concrete methods • Is declared using the abstract keyword • Helps achieve abstraction and code reusability It acts as a blueprint for subclasses, ensuring a common structure while allowing specific implementations. Understanding abstract classes improves design thinking and helps in building scalable and maintainable applications. Grateful to Anand Kumar Buddarapu Sir for the continuous guidance and mentorship throughout this journey. Also thankful to Saketh Kallepu and Uppugundla Sairam for their constant support and encouragement. #Java #OOP #CoreJava #Programming #LearningJourney

⚙️ Java Interface vs Abstract Class This is one of the most important Java OOP concepts. Key differences: Interface: • Full abstraction • No constructor • Uses implements • Supports multiple inheritance Abstract Class: • Partial abstraction • Has constructor • Uses extends • Single inheritance Use Interface for contracts. Use Abstract Class for base classes. #Java #SoftwareEngineering #OOP #Programming

📘 Day 31 | Collections Deep Dive Today we begin a deeper exploration of Java Collections. Understanding the difference between ArrayList and LinkedList is critical for writing efficient code. Remember this: ArrayList → Fast Access LinkedList → Fast Modification Choosing the right implementation impacts performance more than most beginners realize. 📌 Save this for revision 💬 Feedback is welcome #Java #Collections #CoreJava #LearningInPublic #Programming

🚀 Day 18 – Core Java Programming Series Today, I learned about Method Overloading in Java. 🔹 What is Method Overloading? Method Overloading means defining multiple methods with the same name in the same class but with different parameters. The difference can be: ✅ Number of parameters ✅ Type of parameters ✅ Order of parameters 👉 It is an example of Compile-Time Polymorphism. 🔹 Why Do We Use Method Overloading? ✔️ Improves code readability ✔️ Increases flexibility ✔️ Helps in reusing method names for similar operations 💡 Today I solved 19 problems related to Method Overloading and strengthened my understanding of compile-time polymorphism. Consistency is the key to success. Learning something new every day! 🚀 #Java #CoreJava #MethodOverloading #Polymorphism #100DaysOfCode #LearningJourney

Day1 : some basics of java Java Practice – Scanner Class & Data Types This video shows my hands-on practice with Java Scanner class, taking input from users and working with multiple data types. Small programs like these help build strong fundamentals and confidence in coding. #java #coding #LearningJourney #Upskilling #Anand kumar Buddarapu (Mentor) #Saketh Kallepu (Co-Founder)
