There are four fundamental ideas in object-oriented programming: Abstraction Polymorphism Inheritance Encapsulation the delicious acronym A-P-I-E. A pie! Abstraction Abstraction means we focus on the essential qualities of something rather than one specific example. By using abstraction, we automatically discard what’s unimportant or irrelevant.
