What is constructive interface?

Answer 1

Did you mean 'constructive interferance' - where waves from more than one source meet at a point where their energies combine rather than destructively cancelling out.

Answer 2

A constructive interface in programming refers to an interface that guides or enforces certain design guidelines or principles on how classes implementing the interface should be structured. It helps ensure consistency in how classes interact with each other and promotes good software design practices.
