In Java, an object is an instance of a class. A class is a template or blueprint from which objects are created. Everything in Java is associated with classes and objects, along with their attributes and methods. An object has three primary characteristics: identity, state, and behavior. The identity of an object is unique and distinguishes it from other objects. The state of an object is represented by its attributes, which are variables that hold values. The behavior of an object is represented by its methods, which are functions that perform actions.
In summary, an object in Java is a basic unit of Object-Oriented Programming that represents real-life entities. It has a unique identity, state, and behavior, and is created from a class.
