No, they aren't. See http://c2.com/cgi/wiki?DesignPatternsBook

Why do you ask?

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus

Ilja, I was in impression that all those are GOF design pattern.

Thanks for the link.
However, while going through the link, I can see: except IOC design pattern, all the design pattern are suggested by GOF only.

Actually, I am preparing for some interviews now-a-days.
That means, if I am asked about 'what are the design patterns in java'; would usually mean 'what are the GOF design patterns'?.
Am I correct ?

Actually, I don't think that the question "what are *the* design patterns in Java" makes any sense. There isn't a fixed set of design patterns. There is a set of currently known design patterns, and new ones are discovered every year. So if I was asked this question, I would ask for a clarification.

Actually all of those are patterns from Core J2EE Patterns by Alur et. al.
