Java 26 Features and Examples

💫@𝐏𝐫𝐢𝐦𝐚𝐫𝐲 𝐯𝐬 @𝐐𝐮𝐚𝐥𝐢𝐟𝐢𝐞𝐫 𝐢𝐧 𝐒𝐩𝐫𝐢𝐧𝐠 𝐁𝐨𝐨𝐭: When working with dependency injection in Spring Boot, handling multiple beans of the same type can get tricky. That’s where @Primary and @Qualifier come into play 👇 👉 @Primary Used to define a default bean. If multiple beans exist, Spring automatically picks the one marked as @Primary. 👉 @Qualifier Used to explicitly specify which bean you want. Gives you precise control over dependency injection. 💡 Key Insight: Use @Primary for default behavior and @Qualifier when you need specific control. Together, they make your code more flexible and maintainable. #SpringBoot #JavaDeveloper #BackendDevelopment #DependencyInjection #SpringFramework #Java #Coding #SoftwareDevelopment #TechLearning #Developers #Programming #100DaysOfCode #JavaBackend #SpringAnnotations 𝐓𝐡𝐚𝐧𝐤𝐬 𝐭𝐨 𝐦𝐲 𝐌𝐞𝐧𝐭𝐨𝐫: Anand Kumar Buddarapu Saketh Kallepu Uppugundla Sairam

Day 8: Abstraction As OOP grows, not every class needs to define every detail by itself. Sometimes we only want to describe the general idea and leave the exact behavior to the child classes. That is where abstraction comes in. In Java, an abstract class can define a common structure, while abstract methods allow child classes to provide the actual implementation. It helps us focus on what something should do without forcing every detail at the top level. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

Day 1: Classes vs Objects vs Instances Everything in OOP starts here. A class is like a blueprint. It defines what something is. An object is the real thing created from that blueprint. An instance is simply an object created from that class. Simple idea, but this is where everything begins. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee

Dependency Injection is one of those concepts that sounds more complicated than it really is. At its core, it simply means: Instead of a class creating its own dependencies, you give those dependencies to it from the outside. Why does that matter? Because it makes the code: • easier to test • easier to maintain • less tightly coupled • clearer about what it actually needs #SoftwareEngineering #Java #SpringBoot #BackendDevelopment #CleanCode #DependencyInjection #Programming

Today I practiced a simple yet important concept of Object-Oriented Programming — Method Overriding. 🔹 Created a parent class (Shape) with a draw() method 🔹 Overrode the same method in child classes Circle and Rectangle 🔹 Demonstrated runtime polymorphism using a parent class reference 💡 This example clearly shows how Java decides which method to call at runtime based on the object type. 📌 Output: Drawing a Circle Drawing a Rectangle ✨ Concepts Covered: ✔ Inheritance ✔ Method Overriding ✔ Runtime Polymorphism #Java #OOP #Programming #Coding #MethodOverriding #Polymorphism #LearningJourney #SoftwareDevelopment #JavaDeveloper

Sum of the Array in Java | Easy Logic + Coding 💡 Strong fundamentals are the key to mastering programming. This example shows how to find the sum of array elements using simple logic: • Start with an array of numbers • Initialize a sum variable to 0 • Traverse the array using a loop • Add each element to the sum • Print the final result Practicing these basic problems helps build strong logical thinking and coding confidence. 📊 Example Input : [1, 2, 3, 4] Output : 10 🎥 I’ve also created a short video explaining this concept with code: YouTube link : https://lnkd.in/g9SJ3hvJ #Java #Programming #ProblemSolving #Coding #SoftwareDevelopment #Learning #CSE #Developers #LogicBuilding #Arrays

🚀 Code 3 – #50LeetCodeChallenge Problem: 4Sum Given an array of integers and a target value, find all unique quadruplets that sum up to the target. Each element must be used only once, and the solution set should not contain duplicate combinations. 💡 Approach: Sort the array and use nested loops along with a two-pointer technique to find combinations efficiently. Skip duplicate elements to ensure only unique quadruplets are included. 📚 Key Takeaway: Combining sorting with the two-pointer approach helps reduce complexity and is highly effective for solving multi-sum problems like 4Sum. #LeetCode #Java #Coding #ProblemSolving #Arrays #TwoPointers #Programming

Building strong fundamentals, one concept at a time 💡 Understanding the true power of Java — from platform independence to portability — and how “Write Once, Run Anywhere” makes it a game-changer in the programming world. This journey is not just about coding, but about thinking, solving, and growing every day 🚀 #Java #TapAcademy #LearningJourney #Programming #FutureEngineer #TechSkills

Day 5: Inheritance As programs grow, many classes start sharing similar properties or behavior. That is where inheritance becomes useful. Inheritance allows one class to take the properties and behavior of another class. In Java, we use `extends` to create that relationship. This helps reduce repetition and makes code easier to organize when classes are related. #Java #OOP #Programming #SoftwareEngineering #ComputerScience #koofkee
