The Java programming language emerged roughly 25 years ago, when Smalltalk and C++ dominated. Back then it was easy to argue that the world didn't need another object-oriented programming language.

Becoming popular in the early 1990s and the norm today, object-oriented programming (OOP) languages, such as C++ and Java, provide a formal set of rules for creating and managing objects.

One of the features that make Java so powerful, is its object-oriented structure. This means that Java uses classes and objects to create more scalable, modular, and organized code.
