显示从方法到其他方法的所有调用

Question

Let's say I have this code:

public static void main(String[] args) {
    calculate();
}

public void calculate() {
    int n1 = 100;
    int n2 = 100;

    add(n1, n2);
}

public int add(int n1, int n2) {
    int result = n1 + n2;
    return result;
}

My goal is to display all subcalls from the methods in this program.

So when i execute calculate() the result must be printed out like this:

calculate()
    -> add(int, int)

Any idea how to do this? I heard that I can use cflow but i have no idea how.

I would say one way would be to use StackTraceElement, specifically getMethodName(). This site has a tutorial on how to use this method: http://www.tutorialspoint.com/java/lang/stacktraceelement_getmethodname.htm
