What is obj?

obj is a generic term commonly used in object-oriented programming (OOP) to represent an object. An object is a fundamental concept in OOP, representing a self-contained entity that encapsulates both data (attributes) and behavior (methods).

In essence, obj is often used as a placeholder variable name when demonstrating or explaining code snippets that involve interacting with or manipulating an object. The specific properties and behaviors of obj would depend entirely on the class from which it was instantiated. For example, if obj is an instance of a Car class, it might have attributes like color and speed, and methods like accelerate() and brake(). Therefore, "obj" refers to a specific instance of a class . It's a common way to illustrate examples in programming tutorials and documentation.
