Reflectively look at a variable name, rather than value

Given the class:

class Statics {
  public static String LOC_MY_SELECTOR;

  static void find(String selector) {
    System.out.println(selector);
  }  

  public static void main(String...args) {
    find(LOC_MY_SELECTOR);
  }
}

How am I able to, at the point of System.out.println get the field name, rather than the value? The value is null, so of course it will print out null. What I want to do, is:

find(LOC_MY_SELECTOR); // to print "LOC_MY_SELECTOR" instead of the value `null`

Is this even possible?
