Objects are key to understanding object-oriented technology. Objects are the basic unit of object orientation with behavior, identity. These are part of the class but are not the same.
For Example: Car is an object. Its name is Mercedes, color is white etc. known as its state. It is used to drive, so driving is its behavior.
Object is an instance of a class. Class is a template or blueprint from which objects are created. So object is the instance(result) of a class.
What is difference between a class and an object?
A class is model for creating object and does not exist physically. An object is any thing that exists physically. Both the class and objects contain variables and methods.
