object package from object name
Say I had:
int num;
double dec;
String str;
ArrayList arr;
Object obj;
I want to take a String that is the name of an Object and return a String that is the package of the Object.
For example, if the String was "arr", the method would return "java.util.ArrayList".
I looked at the Reflection API, but I couldn't find anything that did this. How do I do this?
