Java for Testers - Part 207 - Interfaces and Object Creation

In this video, I have explained and practically demonstrated the below things related to Interfaces in Java:

- Objects cannot be created for an Interface
- Objects created for the implementing Classes can access Interface implemented methods and class-specific methods
- Assigning the object of implementing class to the variable of the interface
- Casting the Interface variable to access the desired specific method of the interface implementing class
- The purpose of assigning object of implementing classes to the interface variable
