I would be so worried if anybody agreed with me word for word - I spend so much time talking nonsense :-)

Those posts actually made me think what is the major diffence between Perl OO and Java OO.

Interesting question. For me the major differences would be:

• Perl supports multiple-inheritance of implementation.
• Java supports private methods and attributes as native language features.

The static vs dynamic typing also raises issues that affect OO. For example, in Perl we can trivially make containers for any object. In Java this is harder. The addition of generic classes (or whatever they're calling them) in the next Java version should make this a lot easier tho'.

1. In Java, everything is OO

Depends on your definition of everything ;-) It has a bunch of types included for efficiency reasons that aren't "objects". This can mean tedious transformations of ints to Integers, booleans to Booleans, etc.
