Answer
Use appropriate get methods like rs.getInt() or rs.getString().
When accessing data in a ResultSet, use methods that match the expected type of the column. For example, use rs.getInt("quantity") for an integer column and rs.getString("name") for a string column. This ensures type safety and avoids runtime errors due to type mismatches.
