Although not _yet_ a Java programmer, I have a comment on the operator
==.
In a datacentric model, "12345" == "12345"
: but objects also include _behavior_.
If a class ZipCode is derived from class String, then ZipCode("12345") !=
String("12345"), since they probably have a different meaning and intent.
In other words, content != context.
Thanks,
