Simple question, does a list in Java hold objects by value or reference? If I place an object in a list and later on change one of its values, is the one in the list going to have the updated value?

The List is an ordered collection that contains object references.
You can change/update only mutable objects. You cannot update immutable (e.g
List<String>) objects via their references.
