    It is possible to use it with normal Statement's as well (not just PreparedStatement)

    Statement statement = conn.createStatement();
    int updateCount = statement.executeUpdate("insert into x...)", Statement.RETURN_GENERATED_KEYS);
    try (ResultSet generatedKeys = statement.getGeneratedKeys()) {
      if (generatedKeys.next()) {
        return generatedKeys.getLong(1);
      }
      else {
        throw new SQLException("Creating failed, no ID obtained.");
      }
    }
