What is the principle behind the single responsibility principle?

As the name suggests, this principle states that each class should have one responsibility, one single purpose. This means that a class will do only one job, which leads us to conclude it should have only one reason to change.

Which design principle states that classes should not be forced to implement methods they do not use?

Interface segregation principle states: A client should never be forced to implement an interface that it doesn’t use, or clients shouldn’t be forced to depend on methods they do not use.

What is SOLID principle with example?

This principle suggests that “parent classes should be easily substituted with their child classes without blowing up the application”. Let’s take following example to understand this. Let’s consider an Animal parent class. Now let’s consider the Cat and Dog classes which extends Animal.

Which design principle states that clients should not be forced to implement interfaces they don’t use?
