Java: How to get the caller function name

Question

To fix a test case I need to identify whether the function is called from a particular caller function. I can\'t afford to add a boolean parameter because it would break the int

Answer 1

I have no idea why but in my shop the develop system differs from the test and production environments shifting position in the stack. I was forced to loop through the stack to find and get the calling method from the next element in the stack trace. A little clunkier but so far has been consistently returning the desired method. I use this as part of my error handling to identify where an exception was caught.

    List list = new ArrayList();
    StackTraceElement[] elements = Thread.currentThread().getStackTrace();
    for (int i = 0; i < Thread.currentThread().getStackTrace().length; i++) {
        System.out.println("Stack: "
                + i
                + " Class: "
                + elements[i].getClassName()
                + " Method: "
                + elements[i].getMethodName());
        if (elements[i].getMethodName().equals("")) {
            list.add(elements[i + 1].getClassName());
            list.add(elements[i + 1].getMethodName());
             break;
        } // if
    } // for
