Understanding Sun Idemtity Manager using UML Class Diagrams

Question

If you are a Sun IdM beginner and want to quickly and logically understand the relationships between various components in Sun IDM, then you should take a look at this:
http://objectsource.com/blogs/2010/02/understanding-sun-idm-using-uml/
You can also download all the UML diagrams from there.
For those of you who understand UML, you definitely know a UML class diagram is a picture worth 1000 words.
I never remembered all of these, so I used to carry a copy of these with me to custmer requirement and design discussions.
Whenever customer asked details that I could not recall or was not sure, I'd pull these out as a cheatsheet to confirm and further elaborate on the design approach for the Sun IdM feature implementation.
NOTE: I am the author of that blog as well. A little background on this post -
I wrote the blog post a few months ago and totally forgot about it.
A few days back, I installed wordpress site stats on my blog and I was amazed to see how many people look for Google terms "Understanding Sun IdM" and end up at my blog post.
I thought - "Hey If it was so useful to these people, then I believe it will be useful for many more" (especially developers from Java background that have turned to Sun IdM professionals)
Hence the post here.
A few years back, I started using Sun IdM and was absolutely unsure where to start and what relationships exist between various components. I painfully started to understand them by going through the admin console and started drawing out these diagrams. They were sitting in my vault, but I set them free a few months back.
Had I known what I know now, I would have released it much earlier.

Answer 1

playAgain() : bool
askBet() : int
Payout(amt: void) : void
takeBet(amt:void) : boolThese are methods of the "Game" class, and what is inside parentheses are called parameters.
"void" and "bool" are return types.
public boolean playAgain()
    }In this code you have specified boolean as a return type, so you need to return a value of type bool.
As for the void part, you don't need to return anything.
Code should look like:
public boolean playAgain()
         return true; //Or return false
public void Payout ()
         int amt;
    }You need to get :int amt" in the parameters, and since its voide nothing needs to be returned.
public void Payout (int amt)
    }
