Using prepareStatement for auto_increment value

How do we set a value for auto_increment field on MySQL
stmt = con.prepareStatement("INSERT INTO member VALUES ( ?, ? ,? ....) ) ;
stmt.setDate(1, new java.sql.Date(System.currentTimeMillis()));
stmt.setInt(2, ????);
if value 2 is autoincrement. How do we set it?

ThanksWrong, wrong, wrong.
When we said don't set the auto increment column, that meant do not include it in the SQL at all. It does not a bind parameter.
So if your table FOO has columns (ID, X, Y, Z), where ID is the auto increment column, your SQL should be:
String fooInsertSql = "INSERT INTO FOO(X, Y, Z) VALUES(?, ?, ?)";
PreparedStatement ps = connection.prepareStatement(fooInsertSql);
// bind here
int numRowsAffected = ps.executeUpdate();
ResultSet generatedKeys = ps.getGeneratedKeys();
// extract the key from the result set.%
