I'm looking for a way to get the name of the current method without having to create a blank object. Is there a way to do this? This would tidy up our logging code.
Here is what we do now:
new Object() {}.getClass().getEnclosingMethod().getName(

How about Thread.currentThread().getStackTrace()[1]?
Since this enables you to examine higher levels of the stack trace, you could easily wrap this in a helper method (see below). It also gives you the option to get quite a bit more info than just the method name, such as the file name, line number etc.
edit The helper method could look something like this (thanks @Esailija):
public static String getMethodName() {
return Thread.currentThread().getStackTrace()[2].getMethodName();
}

Sr. 0 means current method, 1 means call method – dreamcrash Nov 28 '12 at 16:22

@dreamcrash: Have you actually tried it? I have. – NPE Nov 28 '12 at 16:24

1`public static String methodName() { return Thread.currentThread().getStackTrace()[2].getMethodName(); }` Works great for me – Esailija Nov 28 '12 at 16:30

1@NPE I am sorry, you were right 0 will return getStackTrace. +1 For the inconvenient. – dreamcrash Nov 28 '12 at 16:35

@dreamcrash upvote your comment, because I wonder why we should use [1] and lazy to check what [0] will return :) – nahab Feb 25 '16 at 12:46

Check other question and my answer http://stackoverflow.com/a/8592871/658826 - this one gives you the right method name whatever the index is. – virgo47 Nov 28 '16 at 16:43

You can also use
Thread.currentThread().getStackTrace()[1].getMethodName()
contains the last method call, but is not shorter that
new Object() {}.getClass().getEnclosingMethod().getName
I am not aware of a sorter way to do it.

You can use thread.currentThread().getStacktrace()[0].getMethodName(). But this even takes more time than new Throwable().getStacktrace() (see http://alexradzin.blogspot.co.il/2011/12/how-slow-getstacktrace-is.html)
