Java Design Questions - Class, Function, Access Modifiers
- by Ron
I am newbie to Java. I have some design questions.
Say I have a crawler application, that does the following:
1. Crawls a url and gets its content
2. Parses the contents
3. Displays the contents
How do you decide between implementing a function or a class?
-- Should the parser be a function of the crawler class, or should it be a class in itself, so it can be used by other applications as well?
-- If it should be a class, should it be protected or public class?
How do you decide between implementing a public or protected class?
-- If I had to create a class to generate stats from the parsed contents for eg, should that class be protected (so only the crawler class can access it) or should it be public?
Thanks
Ron
