Can anyone please tell me how to take an object and give it a name using a
string? For example, I have an object of type relation (my own class) called
"rel1", and I want to give it a name like "My relation" so that I can
display this name in a JList instead of the actual object's name ("rel1").

If anyone can help I'd appreciate it. Someone suggested using forname in the
java.lang.class package, but I didn't understand it. I don't know if it is
what I needed anyway. Please could you reply to sc0tt@talk21.com.

Thanks,
Scott

Use a Hashtable. A Hashtable object saves relations between objects.
So, you can, for example, set a string object for every object you
want to rename.

If one uses java 1.2 HashMap (or even TreeMap if sorting is needed)
might be a better choice, if synchronization is not an issue, since they
are faster.
