## What are static methods in interfaces?

The static methods in interfaces are similar to default methods but the only difference is that you can't override them. Now, why do we need static methods in interfaces if we already have default methods?

Suppose you want to provide some implementation in your interface and you don't want this implementation to be overridden in the implementing class, then you can declare the method as static.

In the below example, we will defined a `Vehicle` interface with a static method called `cleanVehicle()`.
