Default Method vs Static Method in Java 8 Interface | Key Differences Explained in Tamil
In this session, we compare Default Methods and Static Methods in Java 8 Interfaces with simple explanations and practical examples.
Both Default and Static methods were introduced for interfaces in Java 8, and both can have method implementations. However, they behave differently.
In this video, you will learn:
✅ What is a Default Method in an Interface?
✅ What is a Static Method in an Interface?
✅ How to declare Default and Static methods
✅ How Default Methods are inherited by implementing classes
✅ How to call a Default Method using an object/reference
✅ Why Static Methods are not inherited as instance methods
✅ How to call a Static Method using the Interface name
✅ Can a Default Method be overridden?
✅ Can a Static Interface Method be overridden?
✅ Purpose of Default Methods — interface evolution and backward compatibility
✅ Purpose of Static Methods — interface-related utility/helper operations
✅ Default Method vs Static Method with practical examples
Easy Memory Point
Default Method → Object/Reference → object.method()
Static Method → Interface Name → InterfaceName.method()
Key Takeaway
A Default Method is inherited by implementing classes and can be overridden.
A Static Method belongs to the interface itself, is not inherited as an instance method, and should be called using the interface name.
