public static void Close(ResultSet rs, PreparedStatement pstmt, Connection conn) {
        try {
            if (rs != null) {　　//ResultSet对象
                rs.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
        try {
            if (pstmt != null) {　　//PreparedStatement对象
                rs.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }

        try {
            if (conn != null) {     //Connection对象
                rs.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
}

写法二

public static void Close(ResultSet rs, PreparedStatement pstmt, Connection conn) {
        try {
            if (rs != null) {   //ResultSet对象
                rs.close();
            }
            if (pstmt != null) {    //PreparedStatement对象
                rs.close();
            }
            if (conn != null) {     //Connection对象
                rs.close();
            }
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

请大佬指点两处代码的错误
