Reverse Linked List Solution in Java

Solved the Remove Duplicates from Sorted Linked List problem using iterative traversal. The idea is to traverse the list and compare current node with next node. If values are same, skip the duplicate node by adjusting pointers; otherwise move forward. Since the list is sorted, duplicates are always adjacent, making it efficient. Time Complexity: O(n) Space Complexity: O(1) #Java #DSA #LinkedList #LeetCode #Coding

💫 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐓𝐲𝐩𝐞𝐬 𝐨𝐟 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐢𝐞𝐬 𝐢𝐧 𝐒𝐩𝐫𝐢𝐧𝐠 𝐅𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤 Today I explored one of the core concepts of the Spring Framework — Dependency Injection and its types. 🔹 𝐏𝐫𝐢𝐦𝐢𝐭𝐢𝐯𝐞 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐲 Injecting simple values like int, String, boolean directly into objects. 🔹 𝐂𝐨𝐥𝐥𝐞𝐜𝐭𝐢𝐨𝐧 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐲 Injecting a group of values using collections like List, Set, Map, etc. 🔹 𝐑𝐞𝐟𝐞𝐫𝐞𝐧𝐜𝐞 𝐃𝐞𝐩𝐞𝐧𝐝𝐞𝐧𝐜𝐲 Injecting one object into another — the heart of Spring DI, enabling loose coupling and scalable design. 💡 Key Insight: While primitive and collection dependencies handle data, reference dependency is what truly powers real-world applications. Understanding these concepts helps in building clean, maintainable, and loosely coupled applications — which is exactly what modern development demands. #SpringFramework #JavaDeveloper #DependencyInjection #BackendDevelopment #Java #SpringBoot #Programming #SoftwareEngineering #Coding #TechLearning #Developers #LinkedInLearning 𝐓𝐡𝐚𝐧𝐤𝐬 𝐭𝐨 𝐦𝐲 𝐌𝐞𝐧𝐭𝐨𝐫 : Anand Kumar Buddarapu Saketh Kallepu Uppugundla Sairam

Topic: Importance of Naming in Code Good naming is one of the simplest ways to improve code quality. Poor naming leads to: • Confusion • Misunderstanding of logic • Slower development • Harder maintenance Good naming should be: • Clear and descriptive • Consistent across the codebase • Reflective of intent Examples: Bad: data, temp, x Good: userAccountBalance, paymentStatus, orderList Naming is not just a small detail. It directly impacts how easily others understand your code. Because code is read more often than it is written. What naming conventions do you follow in your projects? #CleanCode #SoftwareEngineering #Java #BackendDevelopment #Coding

🚀 Abstract Classes (Java) An abstract class is a class that cannot be instantiated directly. It serves as a blueprint for other classes and may contain abstract methods (methods without an implementation). Subclasses of an abstract class must provide implementations for all abstract methods, unless they are also declared as abstract. Abstract classes are used to define common interfaces and behaviors for a group of related classes, enforcing a certain structure and promoting code reuse. They are a core part of abstraction in OOP. #Java #JavaDev #OOP #Backend #professional #career #development

Hello Everyone👋👋 What is method overriding? If a subclass provides a specific implementation of a method that is already provided by its parent class, it is known as Method Overriding. It is used for runtime polymorphism and to implement the interface methods. #Java #backend #frontend #FullStack #software #developer #programming #code #class #object #inheritance #lambda #super #constructor #SpringBoot #SpringAI #AI #GenAI #Java26 #Array #ArrayList #collections #Nodejs #Angular #React #AWS #interview

Hello Everyone👋👋 Difference between Runnable and Thread class You've got two ways to create threads in Java: Extending Thread class: 1)Inherit Thread's methods directly 2)Can't extend any other class (single inheritance limitation) 3)Less flexible approach Implementing Runnable interface: 1)Separates task from thread management 2)Can still extend other classes if needed 3)Generally recommended approach #Java #backend #frontend #FullStack #software #developer #programming #code #inheritance #class #object #AI #GenAI #OpenAI #Claude #Anthropic #LLM #RAG #SpringBoot #Java26 #Arrays #ArrayList #collections #AIDevelopment #multithreading #Nodejs #React #interview
