Welcome to the Java Interview Question Series for Students & Professionals Today's question is "What is the usage of the super keyword in Java?" In Java, the `super` keyword serves as a reference to the immediate parent class of a subclass. This powerful feature enables a subclass to access the members—both fields and methods—of its superclass, particularly in cases where these members have been overridden or concealed within the subclass. By utilizing the `super` keyword, developers can effectively manage inheritance and ensure that the functionality of the superclass is preserved and leveraged in the subclass.

Welcome to the Java Interview Question Series for Students & Professionals Today's question is "What do you mean by the final keyword in Java?" In Java, the `final` keyword denotes that a particular entity—be it a variable, method, or class—cannot be modified or altered once it has been assigned. This keyword effectively establishes the entity as immutable, signifying that its value or behavior is definitive and cannot be changed or extended throughout the program's execution.

Java Interview Question I was asked recently: If we create a class without using the extends keyword, does it still inherit anything? 🤔 (No variables or methods inside the class) Answer: Yes — even if you don’t use extends, every class in Java implicitly inherits from the Object class (unless it’s the Object class itself). #Java #InterviewQuestion #Programming #OOPs

🎯 Most Asked Java Interview Question — Explained Simply! 💡 Why TreeMap doesn’t allow null keys in Java? Because TreeMap maintains its keys in sorted order — either by natural ordering or using a custom Comparator. When you try to insert a null key, it attempts to compare it with other keys using compareTo() or compare(), which immediately throws a NullPointerException. 👉 In short: TreeMap needs to compare keys to sort them, and since null can’t be compared, it’s not allowed! ❌ #Java #TreeMap #CoreJava #Collections #JavaInterview #Coding #JavaDeveloper #TechInterview #JavaTips #Java #TreeMap #CoreJava #Collections #JavaInterview #JavaTips #Programming #Coding #JavaDeveloper #TechInterview #InterviewPreparation #BackendDeveloper #SpringBoot #Microservices #100DaysOfJava

Checked vs Unchecked ✅ Keywords: try, catch, finally, throw, throws ✅ Common exceptions: NullPointerException, ArrayIndexOutOfBoundsException, IOException, etc. ✅ Multiple catch blocks & nested try ✅ Custom exceptions in Java ✅ Best practices (avoiding exception swallowing, meaningful messages) Follow Harshitha Shapuram for more! #Java #Coding #Programming #InterviewPrep #Developers

🚀 Mastering Java Collection Framework Java interviews often test not just your coding, but how well you understand the internals. Here’s a quick refresher to keep you sharp 👇 🔹 Collection Hierarchy: List, Set, Queue, Map — organized for every data need. 🔹 Why Map ≠ Collection: Maps store key–value pairs, not individual elements. 🔹 Fail-Fast vs Fail-Safe: Fail-Fast throws on modification; Fail-Safe stays stable. 🔹 BlockingQueue: Perfect for producer–consumer threads. 🔹 Synchronized vs Concurrent: One lock vs many — simplicity vs scalability. 🔹 HashMap Inside: Buckets + hashCode → O(1) lookups. 💡 Master these basics — and you’re already ahead in Java interviews! #Java #CollectionsFramework #CodingInterview #HashMap #Programming #Developers #JavaTips #TechCareers
