This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Excellent question. UML has a "lollypop" decoration for interface - a short line with an open circle. Anybody know if Java practitioners interpret this literally as a Java interface? I criticized somebody's model recently because I didn't read it that way. Still don't know if he did.
A good question is never answered. It is not a bolt to be tightened into place but a seed to be planted and to bear more seed toward the hope of greening the landscape of the idea. John Ciardi
The "lollipop" is one way to depict an interface - another is to simply use an <<interface>> stereotype on a class.
Stan, how did you interprete the "lollipop"?

I kinda ignored it . Back in the days we were getting Rational mentoring we were doing PowerBuilder. There was no "interface" in the language. We used lollypops to indicate something about a published public API that we expected others to use. We were probably mis-using it to express some scoping concept like public and REALLY public.
As for that recent incident, I was looking for <<interface>> on the diagram and not finding it. Somehow the lollypop didn't register as perhaps the same thing. What I was really looking for was DIP but that wasn't what the author was talking about, so there was pretty major disconnect on my part all along. Sigh, face-to-face wins over diagrams any day.
