When should you use Abstract Class vs Interface while
programming? Give 1 Example
Answer Posted / pravin shrirao
Interfaces are used when we want classes should follow the
rules strictly. Rules like naming coventions e.g. if in
customer class one developer add method AddCustomer other
developer while implementing Invoice class could write
method name InvoiceAdd and also could change the Signiture
rules. for addition of customer we have at client code as
Cutomer.AddCustomer(A,B,C); and Invoice.InvoiceAdd(A,B)
To maintain uniformality if we declare interface and define
method Add(A,B) in that interface and implement that
interface in both the classes then the code will be uniform
all over the classes where ever we have implemented
interface and also all concrete classes must contain
methods which are defined in the interfaces.
