I'm a bit of a newbie to Java and I'm stuck on a problem. Could someone help me please ?
I've posted just the relevant sections of some code (which is quite long).

The problem is:

How to read objects that are defined in an arraylist that is defined as private in another class. The other class has a public get method which returns an arraylist. I've used that, but I don't know how to access the objects inside the returned arraylist.

Please see the attachment at "HERE".

It's close to midnight here so I'll check for responses in 7 hours time...

Thanks in advance...

Amazing what nights sleep will do...

The answer is:

1) use the other classes get method to return the private arraylist defined in the other class.
2) use the arraylist.get() to return the object in the array
3) cast the object as an object type needed
4) assign that object type to an instance variable of that type in the class you are in
5) you now have access to the classes attributes

code like:
ArrayList a1 = vc.getCandidates();
theCandidate = (Candidate)a1.get(0);

Thanks to those who took a look at this. It really had me stumped.
