In System.out.println , out is not a class it is a field of the System class, check API. The field out is of type PrintStream, println is a method of the PrintStream class, you can check the API for the PrintStream class.It is always good t refer to the API if you have such doubts in the future.

Println is a method on an object, and out is a reference to that object. So the method executes on whatever object "out" points to ... some kind of PrintStream. Does that make sense?

Just because repetition sometimes helps, let's go the other way and take this apart into little pieces:

System is a class
out is a static variable on the class
out is a reference to an object instance
that object has a type of PrintStream
PrintStream has the method println

Lots of little bits there!
