Data-Oriented Programming in Java. Data-Oriented Programming (DOP) focuses on decreasing the complexity of the Object-Oriented Programming (OOP) application systems by rethinking data, i.e., separating data and code. DOP divides the system into two core components (Data entities and Code Module), where you can think about each separately.
However, before moving to Data Oriented Programming in OOP languages like Java, it is essential to understand how OOP increases the complexity of creating a system.
