Re: How to access a member constant by FQN

I am curious how, if it's possible, I can access a constant declared
in a class using only a fully qualified name
example:
package com.whatever.mycompany;
public class MyConstants {
public static final Integer MY_CONST = new Integer(10);
}
Object someConst = ...?
With this last line I would like to fully qualify the constant as
"com.whatever.mycompany.MyConstants.MY_CONST"
Object someConst =
com.whatever.mycompany.MyConstants.MY_CONST;
.... which seems so obvious that I suspect I've missed the
point of your question.
It isn't a class I am after but an instance of a class. How do you ask
the JVM for an existing instance in memory???
Now I'm *sure* I've missed something ... MY_CONST is
a reference variable, a static member of MyConstants. It
is initialized (when MyConstants is loaded) to refer to an
Integer object. The Integer exists in memory. When you
initialize someConst, another reference variable, it refers
to that same, already-existing Integer instance. What do
you find unsatisfactory about this state of affairs? (And
how does name qualification or lack thereof enter into the
picture?)
