Programatically obtain name of a variable...
I would like to pass a variable to a method that prints the name of the variable as well as the value.
Given:
String foo ="bar";
publicvoid printInfo(foo){
...
}
Question:
How do I programatically obtain the name of the variable foo (which is of course foo)?
i.e.
Variable Name: foo
Variable Value: bar

Basically, you can't.If your variable is an object variable or a static class variable, you can use reflection to get a Field and get the name from that. Any local (stack) variable names disappear on compile.
That's impossible, and you misunderstand how variables work in Java.Suppose you have a method: printVariableNameAndValue(String s)What should that method print if you'd call it with a literal value, for example: printVariableNameAndValue("hello") ?
