Getting the name of the currently executing method

Technically this will work...

String name = new Object(){}.getClass().getEnclosingMethod().getName();

However, a new anonymous inner class will be created during compile time (e.g. YourClass$1.class). So this will create a .class file for each method that deploys this trick. Additionally, an otherwise unused object instance is created on each invocation during runtime. So this may be an acceptable debug trick, but it does come with significant overhead.

An advantage of this trick is that getEnclosingMethod() returns java.lang.reflect.Method which can be used to retrieve all other information of the method including annotations and parameter names. This makes it possible to distinguish between specific methods with the same name (method overload).

Note that according to the JavaDoc of getEnclosingMethod() this trick should not throw a SecurityException as inner classes should be loaded using the same class loader. So there is no need to check the access conditions even if a security manager is present.

Please be aware: It is required to use getEnclosingConstructor() for constructors. During blocks outside of (named) methods, getEnclosingMethod() returns null.

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

Some virtual machines may, under some circumstances, omit one or more stack frames from the stack trace. In the extreme case, a virtual machine that has no stack trace information concerning this thread is permitted to return a zero-length array from this method.

January 2009:
A full code would be (to use with @Bombe's caveat in mind):

/**
 * Get the method name for a depth in call stack. <br />
 * Utility function
 * @param depth depth in the call stack (0 means current method, 1 means call method, ...)
 * @return method name
 */
public static String getMethodName(final int depth)
{
  final StackTraceElement[] ste = Thread.currentThread().getStackTrace();

  //System. out.println(ste[ste.length-depth].getClassName()+"#"+ste[ste.length-depth].getMethodName());
  // return ste[ste.length - depth].getMethodName();  //Wrong, fails for depth = 0
  return ste[ste.length - 1 - depth].getMethodName(); //Thank you Tom Tresansky
}

More in this question.

Update December 2011:

bluish comments:

I use JRE 6 and gives me incorrect method name.
It works if I write ste[2 + depth].getMethodName().

• 0 is getStackTrace(),
• 1 is getMethodName(int depth) and
• 2 is invoking method.

virgo47's answer (upvoted) actually computes the right index to apply in order to get back the method name.
