How to get the name of the containing function

Question

In C++, you can use __FUNCTION_NAME__ to get the name of the function that contains __FUNCTION_NAME__.

Is there an equivalent in Java? It could, in Java, be possible to do something with this and reflection. Is there something simpler though?

did you try Thread.currentThread().getStackTrace()[1].getMethodName() ? — Alessio, Jan 31 '14 at 09:17
@Alessio: That's neat if a little expensive: and a candidate as an answer. — Bathsheba, Jan 31 '14 at 09:19
@Alessio this doesn't always work. See https://stackoverflow.com/questions/442747/getting-the-name-of-the-current-executing-method — Njol, Jan 31 '14 at 09:22
you're right, I've used in a project and I didn't know that may not work — Alessio, Jan 31 '14 at 09:23

Thread.currentThread().getStackTrace() will usually contain the method you’re calling it from but there are pitfalls

Thread.currentThread().getStackTrace()[ste.length - 1 - depth].getMethodName();

depth = 0 (zero) will give current method

also

System.out.println((new Throwable()).getStackTrace()[0].toString());

Sample output:

com.junk.Junk3.main(Junk3.java:12)
