I'm wondering if this is possible - and after much digging, it seems
that it isn't. I have the following piece of code:
ArrayList<String> stringArray = new ArrayList<String>();
Class c = stringArray.getClass();
Is it possible to, somehow, get "java.lang.String" from c?
Or is that information lost after compiling?

Hmm... it appears that you can't. I would have thought that you could do the following:
Class<? extends ArrayList<String>> c = stringArray.getClass();
which would at least give you the compile-time type, but my compiler is complaining that the assignment:
Test.java:8: incompatible types
found : java.lang.Class<capture of ? extends java.util.ArrayList>
required: java.lang.Class<? extends java.util.ArrayList<java.lang.String>>
Class<? extends ArrayList<String>> c = stringArray.getClass();
^
Am I missing something here??
