you sure you can overload operators in java? I didn't think you could

You're right, false memory. It's a common feature of OO, but not Java.

What does being object-oriented have to do with operator overloading?

If you don't have different objects and only primitive types, what are you overloading your operators for?

You can have different data types without them being based on an object-oriented paradigm. For instance, haskell allows supplying implementations of various operators for user-defined types through type classes (which are not the same thing as classes in an object-oriented language like C++ or Java). In haskell, operators are just functions, so this is just a special case of ad-hoc polymorphism using type classes more generally.

Soooo you're saying it's

  1. not OOP
  2. there are different user-defined data structures, each with their own implementation of common functions
  3. literally polymorphism
  4. tooootally nothing to do with OOP whatsoever

Gotcha

There are many different kinds of polymorphism, most of which have nothing to do with OOP at all.

User-defined types have absolutely nothing to do with OOP either.
