In Object Oriented Programming, an Interface is a description of all functions that an object must have in order to be an "X". Again, as an example, anything that "ACTS LIKE" a light, should have a turn_on() method and a turn_off() method. The purpose of interfaces is to allow the computer to enforce these properties and to know that an object of TYPE T (whatever the interface is ) must have functions called X,Y,Z, etc.
An interface is a programming structure/syntax that allows the computer to enforce certain properties on an object (class). For example, say we have a car class and a scooter class and a truck class. Each of these three classes should have a start_engine() action. How the "engine is started" for each vehicle is left to each particular class, but the fact that they must have a start_engine action is the domain of the interface.
Interface và Abstract class là 2 khái niệm cơ bản trong lập trình OOP. Nhưng phân lớn mọi người cảm thấy mơ hồ và lẫn lộn 2 khái niệm này. Vậy chúng là gì, khác nhau như nào? Tại sao dùng cái này Inte...
