What are 4 pillars of OOPs?

The four pillars of object-oriented programming are:

  • Abstraction.
  • Encapsulation.
  • Inheritance.
  • Polymorphism.

What are ABAP methods?

Methods are internal procedures of a class that determine the behavior of an object. They can access all the attributes of all instances of their class and can therefore change the status of an object.
