Put an on change in each checkbox - when it is set add one to a total, and when it is unset substract one. The form is valid if the total is greater than one?

If he used an on change event, why not deselect all other check boxes before selecting the current one?

Because that's really confusing for the user.

Agreed, but using checkboxes and shoddy logic to implement the functionality of radio buttons is in no way less confusing.

Sounds like you want LinkedList.iterator().next();

grep/egrep will return the lines what match that regex you specify, not the regex itself. You'll need to redirect the egrep output to sed/awk(gawk) to extract the data from the line you want.

Ahh I knew I needed to create the list in some way. I actually had written in
code:
List<Banana> m_Stufflist = new List<Banana>(); 

The problem here is that your List is declared within the scope of the constructor, so after the constructor exits, you won't be able to access that list.

in the constructor and that didn't work. Changing it to:
code:
m_Stufflist = new List<Banana>(); 
worked since I had already declared m_Stufflist earlier.

That second way shouldn't work either. List (java.util.List) is an interface and unlike classes, interfaces can not be instantiated. Did you write your own List class?

I didn't see the part where he mentioned C#. I need to stop assuming code that looks like Java is actually Java
