print the name of a variable
Jan 19th, 2009, 5:13pm  
hi

i am trying to print the name of a variable. either it is totally simple and i dont get it or, well help me out.

for my sketch i wanted to make a small debug function where instead of a normal println(incrementVariable) it not just prints the value of a variable but also the name with it like:

incrementVariable: 10

is this possible, am i not getting it?
thanks
fakob

It is not possible (at least in a simple, automated way).
Of course, you can do:
println("incrementVariable: " + incrementVariable);
A bit heavy-handed but usable.

Maybe it is possible by reflexion or with the debug interface, although I don't know how...

I don't think it is, since reflection only works for Objects, and primitive types aren't objects.

Also the same object can be referenced by many names, and when the program is compiled, the names can easily be stripped since they don't actually matter to the runtime
