So I have been learning about SOLDID-principles.

The I states that you should not have unnecessary methods.

In SOLID I stands for Interface Segregation principle.

Interfaces make applying this easier but it's not required. You can achieve this using inheritance and classes that have a narrower scope of methods. However to do properly interfaces makes it a lot easier.
