    Default Connections to data bases

    When we work with connections to data bases and do operations like select, we must generate the following objects:
    A Connection, a Statement and a ResultSet.
    When finalizing the query one must close the connection and the other objects.
    My question is the following one:
    the ResultSet object, it is created through Statement object, and this through Connection object, is it enough to close the Connection object?, that is to say, to do a Connection.close(), or is it necessary to close the three objects one by one?

    You have that to close one by one.
    The method of the Connection object gives you an object Statement, and the object Statement gives you a Resultset, it does not mean that one “contains” to the others.
    They are objects that “live” in independent form, are in different zones from memory, etc, etc, etc.
