Head First Object Exercise Chapter Two

OK, I'm back. I took a Java course this spring at the local college, and learned enough to know I don't know what I'm doing. I'm now starting Head First Java with a study buddy. We're in Chapter Two - Objects, It's one of those complete the code from a list of "snippet" things. We chose different codes, yet have the same output. Neither of us can explain why we chose the differing snippets other than we worked it through our heads and this one worked. Can someone explain which of the coding is preferred and why? or does it matter and both are right.


My Coding

His Coding

BTW -- My coding agrees with the book, so I assume his is wrong, but I can't show him why.

Thanks again

The exercise was to fill in some gaps and get the code to print 10 right?
Then if both of you have used available code snippets, you are both right.

It just happens sometimes - there is not one correct answer, but multiple.

Add some println statements, and you will see the different behavior...
