About Question enthuware.ocpjp.v7.2.1373 :

[EpicWestern]

Another reason code will not work is that rs.getString(0) is invalid.

[bluster]

To the point of the previous poster, it seems inaccurate to state "after the try block ends without any exception".

Note the certainty that invocation "getString(0)" will throw java.sql.SQLException: Invalid column index.

Please explain if possible. That throw is not mentioned in the explanation, and as said above the enunciated premise of the question does not seem to hold.

[admin]

You are right. It has now been changed to getString(1).

thank you for your feedback!
Paul.
