[chuck-users] parent and children classes (I meant polymorphism)

[mike clemow]

Michael,

Hrm...  Yes, you're right; we've gone over this before.  How do you
represent objects in your ArrayList class?  Are you using arrays?  If
yes, how do you avoid the issues that are brought to the surface by my
code?  I'd be surprised if you haven't run into the issues with Arrays
of Objects that Kassen is talking about.
