You have a class that directly instantiates concrete implementations of its dependencies. Which SOLID principle should be applied?

You have a class that performs both file I/O operations and data validation. Which SOLID principle should be applied?

You have an abstract class with a method that has an empty default implementation, and its subclasses override only the necessary parts. Which SOLID principle should be applied?

You have a class that has tight coupling with another class, making it difficult to modify independently. Which SOLID principle should be applied?

You have a base class Vehicle with a method startEngine(). You have a derived class ElectricVehicle that inherits from Vehicle. However, when calling the startEngine() method on an ElectricVehicle object, it throws an exception because electric vehicles do not have an engine.Which design pattern is getting violated here?
