How do I get the name of a variable in Java?

Possible duplicate:
Java Reflection: how to get variable name?

I have found various discussions on this topic, but have never answered them.

A anyVariableName = new A();

How can I get the name of the variable anyVariableName

and get the string "anyVariableName"

in the result? Is this possible in Java?

If anyVariableName

is a local variable, you cannot. If this is a field, use Class#getField()

or Class#getDeclaredField()

.

The only local names of local places are stored in source (which you can parse) or debug information (which you can get from bytecode if it was included)



If it's a field, you can use Class.getDeclaredFields () if you don't know the name.
