    StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace()


    According to the Javadocs:


    The last element of the array represents the bottom of the stack, which is the least recent method invocation in the sequence.


    A StackTraceElement has getClassName(), getFileName(), getLineNumber() and getMethodName().

    You will have to experiment to determine which index you want (probably stackTraceElements[1] or [2]).

    Sounds like you're trying to avoid passing a reference to this into the method. Passing this is way better than finding the caller through the current stack trace. Refactoring to a more OO design is even better. You shouldn't need to know the caller. Pass a callback object if necessary.
