OO means (Java)? etc

Question

Java is an Object Oriented language.

What does OO actually mean

Answer 1

With programming, you create objects and assign attributes to them at will, as opposed to functions or tasks to perform the same thing.

So let's say you want to write something to a file. Instead of creating inline programming or a subroutine to perform this task,  you create a file-writing "object" that accepts parameters for it's attributes, for example, input file, output file, file type management, etc.

Most languages support OO. That's really all it means; a language that supports object creation.
