Accessing a changing field within a java object

I have a function that is looking up an identification tag in an object based on a string. The string can be either in the name field or the comment field if the name field doesn't exist.
Example: name field
obj.name
Example: comment field
obj.comment
I have a function that allows the user to specify the object and which field they want
function(obj,field)
How do I construct a call to the object field from this?
If I simply put something like
obj.field
I get an error because field is not a valid field in the object.
Thanks!
