What is SOLID Principle in OOPS
Single Responsibility Principle states that every object should only have one reason to change, i.e. every object should perform one thing only. Open-Closed Principle states that classes should be open for extension and closed for modification. Liskov Substitution Principle states that you should be able to use a derived class in place of a parent class and it must behave in the same manner. Interface Segregation Principle states that clients should not be forced to depend on interfaces they do not use. Dependency Inversion Principle helps to decouple your code by ensuring that you depend on abstractions rather than concrete implementations.
