Nettet24. mai 2024 · Abstraction is a technique used in Object-Oriented Programming to separate the interfaces of classes from the implementation details of each individual object. This means that the code can be changed without altering the code which uses the class. NettetAnd there is a abstraction function that abstracts the internal details to the outside: f ( (1, 1)) = [1] f ( (-1, -1)) = [1] It maps from concrete values to the abstract values of an object. You do that by writing for example a constructor mapping (-1, -1) to (1, 1) and by writing a equals function for your class. Polymorphism
