Lecture - 19 | Shallow Copy vs Deep Copy in Java | Key Differences with Practical Examples
🧠 Understand Shallow Copy vs Deep Copy in Java – Explained with Code!
Confused about how object copying works in Java? 🤔 In this beginner-friendly video, we’ll explore the key differences between shallow copy and deep copy, including how they behave in memory and how changes affect copied objects.
Using simple, practical code examples, you'll learn:
What shallow copy is and how it only copies object references
What deep copy is and how it creates an entirely new object with copied data
How modifications in the original object affect shallow and deep copies
Real-world use cases and how to implement deep copy manually
🔍 What You'll Learn:
Difference between shallow and deep copy in Java
How shallow copy works using clone() or assignment
How to implement deep copy using constructors or serialization
Step-by-step code walkthrough for both copies
