What is an object in Java?

In Java, an object is a fundamental building block of a program. It is an instance of a class, which is a blueprint that defines the behavior and state of the object. As such, an object is a self-contained entity that can hold data and perform operations on that data. Objects can interact with each other and with the program's environment through methods, which are functions associated with the object's class. In essence, objects in Java are the embodiment of the object-oriented programming paradigm, which emphasizes modular design, encapsulation, and abstraction.
