Question

I have the following scenario where
both testOne() and testTwo calls same callMe() method.

How do I decide inside callMe() method who called callMe().

public void testOne(){
    callMe();
}

public void testTwo(){
    callMe();
}

public void callMe(){
    System.out.println("I was called by following method."+methodName);     

}


Any sort of help is appreciated.

Answer 1

Any solution that has you generating a stacktrace and looking at the second frame is one that is going to lead to pain – what you are essentially doing is bypassing the idea of passing what a function needs to it in order for the function to do it’s work.

If you need the name of the caller method, then just pass it as a parameter. If you need some other piece of data to decide what to do in the callMe() method, pass it (as a boolean, int, etc.).

It will confuse other developers working on your code why callMe() has what are essentially secret parameters.

public void testOne(){
    callMe("testOne");
}

public void testTwo(){
    callMe("testTwo");
}

public void callMe(String methodName){
    System.out.println("I was called by following method."+methodName);     
}
