There are cool software tools and there are practical tools. People who make their living by developing enterprise Web applications are very careful in selecting the language or technology for their needs. There is a huge difference in requirements for developing an application like Google maps and the enterprise-grade high availability business applications. Anatole Tartakovsky of Farata Systems (pictured) is one of these programmers who know pretty much everything. He lives and breathes programming. If he does not know the answer to your problem today, he'll know it tomorrow. Flex Developer's Journal have asked Anatole some tough questions that concern most of the enterprise developers who are considering Adobe Flex 2 as a tool for their next Web application. Q . How hard is it for typical Java EE developer with Struts and DAO skills to add Flex to their skill set? A. I would say, the hard part is over. Flex allows seamlessly integrate your Web client with the J...

1) What’s the difference between Java and AS3 getters and setters? In Java, getter and setter methods have to be explicitly called. While in AS3, they’re called automatically and externally indistinguishable from public properties. For instance trace(myClass.foo) might be referencing a public property or it might be referencing the method “public get foo():Object”. It makes no difference to an external class. — You can expand on this a bit more to describe why this is useful. The implications are that, unlike in Java, all variables in a class are generally public. Java standard practices are to create only public getters and setters while keeping the variables private. The reason for only allowing methods to be publicly accessible is so that 1) they can be overridden and 2) their implementation can change without altering class interface.
