Java ResultSet how to check if there are any results

Question

Resultset has no method for hasNext. I want to check if the resultSet has any value

is this the correct way

if (!resultSet.next() ) {

    System.out.println("no data");

}

Answer 1

That's right, initially, the ResultSet's cursor is pointing to before the first row if the initial call to next() returns invalid then there was no data in the ResultSet.

If you try this way, you may have to call beforeFirst()immediately after to reset it, since it has placed itself past the first row now.
