Default Methods in Java 8 Explained | JVM Internals | Java 7 vs Java 8

In this video, we deep dive into DEFAULT METHODS in Java 8 and understand how JVM internally resolves method calls compared to Java 7. Before Java 8, interfaces were purely abstract and JVM never executed any code from interfaces. Adding a new method to an interface would break all existing implementations. Java 8 solved this problem by introducing DEFAULT METHODS. But how does JVM execute default methods? Does JVM behavior change compared to Java 7? What is the method resolution order? In this video, we answer one BIG question step by step: 👉 How does JVM resolve default methods in Java 8 without breaking existing code? 📌 Topics covered in this video: ✔ Interface behavior in Java 7 ✔ Why JVM never executed interface methods before Java 8 ✔ What changed in Java 8 (default methods) ✔ JVM method lookup order (Class → Superclass → Interface) ✔ How backward compatibility is preserved ✔ Diamond problem and conflict resolution ✔ Interview-level JVM explanations ✔ Java 7 vs Java 8 comparison (internals) This video is explained in a SPOON-FEEDING manner using: ✔ Real-time examples ✔ Tablet/whiteboard explanations ✔ JVM-level reasoning ✔ Interview-safe explanations 🎯 Who should watch this video? • Java beginners • Backend developers • Interview preparation (2–10 years) 👍 Like the video if it helped you 💬 Comment your doubts – I reply personally 🔔 Subscribe for deep Java & JVM concepts #Java8 #DefaultMethods #JVMInternals #JavaInterview
