After you have obtained a "ResultSet", for example:
Connection dbConn = ... String qry = "SELECT ..." Statement stmt = dbConn.createStatement(); ResultSet rs = stmt.executeQuery(qry);
then if that "ResultSet" is 'empty', the first invocation of the "ResultSet" methos "next()" will return 'false', as in:
rs.next(); // returns 'false' if no "next" row.
Hope this answers your question.
