google reflections - Java - determine where an object is instantiated from object's class -

say have class called myclass, within class, want find out class name instantiated object of myclass, example:

class myclass {     final string whocreatedme;     public myclass() {         whocreatedme = ???     } }  public class driver {     public static void main(string[] args) {         system.out.println(new myclass().whocreatedme); // should print driver     } } 

this not advisable, , breaks in unexpected (and expected) ways. hope you're not going use in production code.

public class temp {      static class testclass {         public final string whocreatedme;         public testclass() {             stacktraceelement ste = thread.getallstacktraces().get(thread.currentthread())[3];             whocreatedme = ste.getclassname();         }     }      public static void main(string[] args) throws exception {          system.out.println(new testclass().whocreatedme);     } }
