Object-oriented programming (“OOP”) is a language model designed around objects rather than logic. As developers and programmers, we are more interested in how we care about the objects we want to manipulate rather than the logic required to manipulate them.
OOP looks at all of the objects we need to manipulate in a program and how they relate to each other which is also known as data modeling. Data modeling defines objects and classes to reflect the kind of data they contain and how to use logic sequences to manipulate these objects.
Each logic sequence is known as a method and developers use well-defined interfaces called messages to allow objects to communicate with each other.
Some of the most popular OOP languages today are Python, Java, C++ and Ruby. Java is used primarily for distributed applications on corporate networks and the Internet.
