Suppose I were to have a parent class A- with 3 attr..
Now There are two child classes of this...
I inherit them,,,and do the necessary logic...Later on...the client
asks for certain modifications...which makes it necessary for me..to change my parent class...
What i want to know is that...
Its easy if we want to add attributes to an existing design structure but not scale down an existing parent class more so if there are
numerous sub classes...
Except of course if u are willing to spend time on lot of refactoring ..
Thnk u
