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
