Got a copy of the new head first OO book...
Question on Class Diagram in particular Interfaces and representation.
In UML 2.0 reference books Interface methods/attributes are not italics
in particular in Learning 2.0 and other UML references in basically says.."..unlike abstract classes, an interface does not have to show that its operations are not implemented, so it does not have to use italics."...
But in Head First OO (p. 224 and others) and in other
Java programming books...Interfaces are italicized in UML..
Questions.
1. Why the incosistencies?
2. Which is correct- italic or non italics...or is it optional and if so why not say so- instead say one way or other...
I thought this question was answersd a while back but there seems to be inconsistent in notation..jc
