Refer to current filename and line.

java-programmer, Refer to current filename and line. Hi,

I remember this was possible in C with macros. Is it possible in Java
to refer to the current file name and line number as in

System.out.println( something.that.returns.current.file.name() + "
printed this line.");

Many thanks in advance!

As of Java 5, you can also go via the ThreadMXBean.getThreadInfo().
I've not tested, but I wonder if there could be a sliiight performance
gain because you can specify that you only need the top stack trace
element(s). (The code would be uglier, of course.)

You can also call Thread.currentThread().getStackTrace(), but internally
this appears to just create a Throwable and query it, so it depends
which code you like looking at...!

See http://mindprod.com/jgloss/trace.html

do a new Exception() then use the methods for exam inning the stack
track fields.
