Answer
Use the rs.next() method. Frame the concept in practical terms so you can explain it during interview discussion.
In JDBC, the ResultSet cursor starts before the first row. To iterate through each row, you use the rs.next() method, which moves the cursor to the next row and returns false when there are no more rows. This is typical in a loop to process each row of a query result.
