[@ATHARVATHEDRUMMER]

What is the difference between OCP and DIP? Here in both cases you used abstraction as central concept, but why do we have 2 different principles?
Also It would be great if you can include what problems we face if we violate each of these principles like difficult to make a simple change, a change causing unexpected side effects, difficult to reuse, difficult to read and understand and hence maintain ... these things are also important in addition to know the principle.

[@rakeshpadsala8751]

Hello, thanks for great content. I have been watching videos uploaded on this channel. For this specific content, I have a question. For "Interface segmentation principal". We are saying that interface should be segemented in a small piecies so that client don't need to implement unnecessary function. Going by this principal, is it correct to state that VendingMachine LLD design can be improved such a way that different states defined in the design don't have to implement unnecessary methods?

[@ConceptandCoding]

Hi Rakesh, Vending Machine is not breaking the Interface Segregation principle, i have described it my Live LLD session video, kindly have a look.

[@ramyasruthi5372]
