String setToString(
  1. Set set

Converts a Set to a String.

Converts set to a string by converting each element to a string (by calling Object.toString), joining them with ", ", and wrapping the result in "{" and "}".

Handles circular references where converting one of the elements to a string ends up converting set to a string again.
