The video tutorial provides an overview of interface concepts, explaining their significance and application in various contexts. It aims to clarify the fundamental aspects of interfaces and how they contribute to effective communication and functionality in systems.

What is the primary purpose of an interface in programming?

• To provide a blueprint for classes

• To compile programs

• To store data

• To execute code

Which of the following is a characteristic of an interface?

• It can contain implemented methods

• It can have instance variables

• It can be instantiated

• It can only contain method signatures

How does an interface differ from a class?

• A class cannot implement an interface

• An interface can have private methods

• A class can implement multiple interfaces

• An interface can have constructors

What is a benefit of using interfaces?

• They allow for multiple inheritance

• They increase code redundancy

• They make code less flexible

• They prevent code reuse

In what scenario would you use an interface?

• When you want to create a new data type

• When you want to define a contract for classes

• When you need to store data

• When you need to execute a program
