How to design Java Programs

[KOla Oyedeji]

Hi I'm new to Java and just wondered how people design Java programs. I have heard mention of UML is this the industry standard and if so does any one have any good resources for it?
Thanks in advance

Kola, since you are new to Java, it will be best if you gety a java textbook or the free tutorial at sun's site. This will get you started on the right track, and it will answer a lot of the begginner question you may have. Some good texts are Beginning Java2 by Ivor Horton, and Thinking in Java by Bruce Eckel (A little advanced though). Definitely get the Java Tutorial at Sun's site first!

UML is a modeling methodology not necessarily restricted to Object Oriented design, but the most used by OO designers.
The OO Design approaches used by Java designers is not restricted to Java, the concepts are the same as those in any other OO language.
We have an OO Design and UML forum for those interested.

Hi Kola,
If u are interested in getting your feet wet in UML, try this book: UML Distilled - Fowler&Scott. VERY good book for beginners in UML. To get a better grip on UML, you need to get a more in-depth book.
UML is basically a tool to analyze your business requirements/logic and break them down to the level of what goes in each class, how to structure your packages to meet ur needs, etc.
Once you identify your classes, packages and other components, it doesn't matter what OO language u use.
Hope this helps.

Thanks guys for your replies so UML is not limited to OO design and it can be used for any OO language not just java. I'm a web developer and wondered if UML was actually the industry standard for designing classes/applications in Java are there any other popular standards/modelling techniques/methodologies.
Its just coming from a web development background I am at a loss as to how to design my applications.
Thanks in advance.

If the application is not too large:
> Make everything a class.
> Figure out how the classes are related to one another: IsA or HasA.
> Refine your classes, start writing code.
