Works?

Factory classesInterceptor

classesProxy classes

Factory Code

Generation

if a class is suffixed with factory and it is passed to the object manager or in the constructor and if the class is not existing then magento will create the class automatically.

Plugin Code Generation

if a plugin is defined in the di.xml, then its interceptor class is created in the var/generation .

Proxy Code Generation

since magento2 uses DI design pattern and you can pass the class reference in the constructor and when the class is loaded is starts a domino effect to overcome this problem magento2 uses proxy design pattern .
