How do I create a Java object from the resultset of a select query?

Question

Connection to JDBC is working fine. This is the code which accesses database tables. File name –

FlightDB.java Schema – Flights1(flno int, time timestamp)

Answer 1

You should return flight1 object not flight as shown below:

public static Flight selectFlight() throws SQLException{
    PreparedStatement ps = null;
    ResultSet rs = null;
    String q1 = "Select * from Flights1 f order by f.time";
    Flight flight1 = null;
try{
    ps = connection.prepareStatement(q1);
    rs = ps.executeQuery();
    if(rs.next()){
        flight1 = new Flight();
        flight1.setflno(rs.getInt(1));
        flight1.settime(rs.getTimestamp(2));
        // System.out.println(“new flight:” +flight1.getflno()); Correct output printed here
        }
    }
finally{
    closeResultSet(rs);
    closePreparedStatement(ps);
}
    return flight1;
}

Also, DO NOT use while for single record, rather use if for single record.
