Class and Object in Java with Examples

In real-world an entity that has state and its behavior is known as an object.

For Example:

• A Car is an object. It has states (name, color, model) and its behavior (changing gear, applying brakes).
• A Pen is an object. Its name is Parker; color is silver etc. known as its state. It is used to write, so writing is its behavior.

In real-world object and software object have conceptually similar characteristics. In terms of object-oriented programming, software objects also have a state and behavior.
