An object is a single, specific item created in your program. Think of it as an actual house built from a design plan.

Objects are Individual Items

A class is the master plan or design used to create objects. It defines what information the object holds and what actions it can take.

Classes are Master Blueprints

Attributes are the characteristics that describe an object, such as its color, height, or name. They represent the data stored inside the object.

Attributes are Object Traits

Methods are the actions or tasks that an object can perform. They are like instructions that tell the object to do something, like 'start' or 'stop'.

Methods are Action Behaviors

This concept bundles data and actions together while hiding the messy inner parts. It protects information so it cannot be changed by accident.

Encapsulation Groups Data

Abstraction simplifies things by showing only the necessary features to the user. You can drive a car using a steering wheel without knowing how the engine works.

Abstraction Hides Inner Workings

Inheritance allows a new design to copy features from an existing one. This makes it easier to create specialized versions of a general idea.

Inheritance Passes Down Traits

This lets different objects respond to the same command in their own unique way. For example, a 'Play' button might start music or a movie.

Polymorphism Adapts to Context

A constructor is a special process that runs when you first create a new object. It gives the object its starting values, such as its name.

Constructors Set Up Objects

The state is the collection of values an object has at a specific moment. For instance, a light bulb object's state could be 'On' or 'Off'.
