Java Inheritance and Access Specifiers Explained

Java started as version 1.02—slow, limited, but loved for its simple syntax, object-oriented design, memory management, and “write once, run anywhere” promise. Early programmers struggled with bugs and slow performance, but their dedication paid off. Today, Java is faster, more powerful, and much easier to use. If you’re learning Java now, you’re lucky to start with this modern, sleek version! #Java #Programming #Coding #SoftwareDevelopment #LearnJava #TechJourney

Hello Connections 👋 Today I practiced a Java concept called Anonymous Class. An Anonymous Class is a class without a name that is created and instantiated at the same time. It is mainly used when we want to override a method for one-time use without creating a separate class. In the example above: • I created a Parent class with a method "message()" • Then I used an Anonymous Class to override that method • When the object calls "obj.message()", the overridden method from the anonymous class is executed 💡 This helps developers write quick implementations and reduce unnecessary class creation.

🚀 Day 17 of #100DaysOfDSA & Java Development Today I explored one of the most interesting problem-solving techniques in programming — Recursion. Key concepts covered: 🔹 Understanding recursion and the importance of the base case 🔹 Recursive function calls and stack behavior 🔹 Solving problems like factorial, Fibonacci, and printing numbers using recursion 🔹 Practicing recursion-based questions to strengthen logical thinking Recursion really changes the way you think about solving problems. Instead of solving the whole problem at once, you break it into smaller versions of the same problem. Big takeaway: Every recursive solution depends on two key parts — base case (stopping condition) and recursive call (reducing the problem).

#Day17 – Understanding Constructors in Java ⚙️ Today’s session helped me understand how constructors work in Java and how they are used while creating objects. Key Learnings: ✔ A Constructor is a special type of method whose name is the same as the class name ✔ Constructors do not have any return type, not even void ✔ Constructors are automatically called when an object is created using the new keyword ✔ If a programmer does not create any constructor, Java Compiler provides a Default Constructor ✔ Learned about Parameterized Constructors and Zero-Parameterized Constructors ✔ Understood Constructor Overloading (multiple constructors with same name but different parameters) ✔ Explored Constructor Chaining using this(), where one constructor calls another constructor within the same class TAP Academy Harshit T #Java #OOPS #CoreJava #Constructors #Programming #SoftwareDevelopment #LearningJourney #Consistency

“Finally, final is actually final” — Java 26 update 👀 Came across this recently, and honestly, I didn’t even realize before that final had some edge cases where it didn’t behave as strictly as we’d expect. Looks like Java 26 is making things more consistent now. I actually like these kinds of improvements: -clearer behavior -fewer surprises in code -easier to reason about things Goes to show there’s always something new to learn, even in concepts we think we already know 🙂 #Java #Java26 #Programming #Developers #Learning

🚀 Day 8/45 – Taking User Input in Java using Scanner On Day 8 of my Java learning journey, I learned how to make programs interactive by taking input from the user. Until now, I was using fixed values in my programs, but today I explored how to accept dynamic input using the Scanner class. 📚 What I Learned Today Today I learned: ✔ How to use the Scanner class from java.util package ✔ Taking input using methods like nextInt(), next(), and nextLine() ✔ Writing programs that respond based on user input 💻 Practice Work To apply my learning, I implemented: • Addition of two numbers using user input • Even or odd number checker using input • Simple interest calculator using user-provided values 🎯 Key Takeaway Taking input from users makes programs dynamic and interactive. This is an important step toward building real-world applications. Practicing daily is helping me improve both my coding and problem-solving skills. #Java #Programming #LearningInPublic #software #CodingJourney #SoftwareDevelopment #Consistency

Inheritance in Java – The Foundation of Code Reusability Inheritance is a core concept of Object-Oriented Programming (OOP) that allows one class to acquire the properties and behaviors of another class. It helps in building reusable, scalable, and well-structured applications. Inheritance Components Parent Class (Superclass) – The class whose properties and methods are inherited Child Class (Subclass) – The class that inherits from another class using the extends keyword Method Overriding – Redefining a parent class method in the child class super Keyword – Used to access parent class methods and constructors Understanding inheritance is essential for writing clean, reusable, and maintainable Java code. It promotes code reusability, improves readability, and supports hierarchical classification. Strong knowledge of inheritance leads to better application design and efficient object-oriented development. #inheritance #fullstack #javafullstack #TAPACADEMY

💡 Mastering Java Input: next() vs nextLine() – A Must-Know for Every Developer! While working with Java’s Scanner class, one common confusion developers face is the difference between next() and nextLine()—and trust me, this small detail can lead to big bugs if not handled correctly! ⚠️ 🔹 next() Reads only a single word and stops at whitespace. Perfect for capturing simple inputs without spaces. 🔹 nextLine() Reads the entire line, including spaces, until the user hits Enter. Ideal for full sentences or strings with spaces. 🚨 The Hidden Trap – Buffer Issue When using methods like nextInt(), a newline character (\n) is left behind in the buffer. This causes nextLine() to skip input unexpectedly—something many beginners struggle with. ✅ Quick Fix Use an extra nextLine() after numeric inputs to clear the buffer: scanner.nextInt(); scanner.nextLine(); // clears leftover newline 🎯 Key Takeaway Understanding how input buffering works in Java can save you hours of debugging and make your programs more reliable. 📌 Small concept, big impact! Mastering these fundamentals is what separates good developers from great ones. #Java #Programming #JavaDeveloper #CodingTips #100DaysOfCode #SoftwareDevelopment #LearnToCode

Day: 24 Problem Solved: Finding the Majority Element in Java Today I worked on solving the Majority Element problem using Java. 📌 Problem Statement: Given an integer array, find the element that appears more than ⌊n/2⌋ times in the array. 💡 Approach Used: I implemented an efficient approach that solves the problem in: O(n) Time Complexity O(1) Space Complexity The idea is to maintain a candidate for the majority element and adjust a counter while traversing the array. If the count becomes zero, the current element becomes the new candidate. 📊 Example Outputs: [3,2,3] → 3 [2,2,1,1,1,2,2] → 2 💻 Implemented using Java and tested with multiple inputs. Practicing these problems helps strengthen problem-solving skills and algorithmic thinking, which are essential for software development. #Java #DataStructures #Algorithms #ProblemSolving #CodingPractice #Programming Raviteja T Mohammed Abdul Rahman 10000 Coders
