If it is a class member you could conceivably use reflection to see if a
given object/class has a member you name

The only other possible way I can think of, and I would have to do so
experimenting to see if/how exactly it would work, would be something
like:
try {
Object a = b

how about instead of using a declared variable, use an appropriately scoped
attribute? You won't get a compile-time error retrieving a named attribute.

For additional commands,
Is there a way to, at runtime, check if a variable is declared? I have
some code that I want to behave differently depending on whether or not
a variable has been declared. I tried using a try catch block but it
gets caught at compile time.
Thanks

If it is a class member you could conceivably use reflection to see if a
given object/class has a member you name... if it's local though, no,
it's a purely compile-time check.
Do you really mean declared or do you perhaps mean initialized?
