Thanks for the link, yes it does. I've used DOM parsing in PHP before but was a bit confused because in Java it seemed throw in another step which I didn't quite understand. Turns out I...

Hi I'm using the DOM XML parser classes and wandered if this is a correct perception:



Element eElement = (Element) node;
NodeList feedlist = eElement.getElementsByTagName("url");
Element...

Ah I understand what you mean the problem is exchangerates must know the currentcurrency value to retrieve the info as I don't want to achieve the currency info for all countries as they all have...

Thank you for your reply. By encapsulating exchangerates in converter do you just mean effectively merging the two classes? My understanding is that it is best to have each class do one job only. I...

Thanks for clearing up what I made a terrible mess of trying to say haha!

I think this will clear things up for you; abstract methods are methods that are not implemented. In order to actually use these methods you must override them in the child classes to implement...

Hmm the only example I can provide is a number guessing game I made. I had guessinggame as an abstract classwhich normalgame and testgame extended. I set guessinggame to abstract because I didn't...

I was looking into using a database with one of my programs myself, and I believe you can utilise the JDBC driver.

Hi there, I'm working on a currency converter which uses XML to dynamically retrieve exchange rates. Below is my class diagram so far:

Thank you for your reply. I did actually do something like what you suggested for one of my latest projects. It was a Software Design assignment project so very focused on the documentation, I was...

I guess you're right on the database point, I'm not that experienced with using SQL (I've only done more of a general module on relational databases and normalisation so far). I'm just trying to...

Hi there guys. I have secured an interview for an industrial placement and they have asked me to bring a few examples of my work, the problem is not much of the stuff we've done for assignments is...

Thank you for very much! The concrete no parameter method and abstract method with the parameter works perfectly. Sorry if the problem was difficult to understand I didn't quite understand the...

Thought I'd update you on a couple of changes I made. In my parent class I adjusted the method I wanted to overload in the child classes to abstract with no parameters. This meant I could simply...

Thank you for your reply. That very nearly was what I was trying to convey, I believe I may have been going about it wrong now. The following is what I wish to achieve:

public abstract class...

Hey there. I'm making a game that utilises two different modes which inherit from an abstract class. The basic aim of what I'm trying to achieve is to use polymorphism so that depending on the mode...

I think you have understood what I was trying to say, but retrieving the objects that way would still require the ArrayList to be public to be read from would it not?

Basically I need public...

Hi there. I've been working on a side project outside of class (I'm a Software Engineering student at Uni) which is really just a simple Banking system to help my understanding of Java. Basically the...
