How to copy all the values from one JSONObject to another?
After hours of searching, I finally found the answer. I'm sort of embarrased that it's this simple.

Json-lib has a beautiful feature that allows you to take your current JSONObject and parse the entirety of the JSONObject into a String. And there already exists a method to build a JSONObject from a String. Therefore, all you need to do is turn the JSONObject into a String, and then back into a JSONObject. You could store the string as a variable (or use it as a return value), then simply take your preexisting JSONObject reference and use the method to rebuild the JSONObject from the String. Simple as that.
EDIT - thought I would give a quick code example
JSONObject a = /* pretend a has 100 elements inside */String temp = a.toString();JSONObject b = JSONObject.fromObject(temp);String temp2= b.toString();if(temp.equals(temp2)){System.out.println("Well done.");}
