About Question enthuware.ocpjp.v7.2.1344 :

[The_Nick]

Hi,
From your explanation quoted by the javadoc:


" between the values 'Alpha' and 'Bravo' both values inclusive"

Why should it be both value inclusive? even in the tutorial it says that they are inclusive however if a programmer wants to implement predicate using > instead of >= can, and in that case the range would be exclusive.

Is it to be taken only as a suggestion?

Thanks in advance.

Yes, this is only for the example given in the API description http://docs.oracle.com/javase/7/docs/ap ... owSet.html

Will update the explanation to make it clear.

HTH,
Paul.

A FilteredRowSet cannot be scrolled in both directions. Explanation : All RowSets are scrollable.

The explanation is partially true because if we create JdbcRowSet using ResultSet which was not updatable or scrollable then neither would JdbcRowSet be. Please see http://docs.oracle.com/javase/tutorial/ ... owset.html
Section Passing ResultSet Objects.

The second line in the link that you've mentioned says, "One of the main uses of a JdbcRowSet object is to make a ResultSet object scrollable and updatable when it does not otherwise have those capabilities."

As per http://docs.oracle.com/javase/7/docs/ap ... owSet.html

Another advantage of a JdbcRowSet object is that it can be used to make a ResultSet object scrollable and updatable. All RowSet objects are by default scrollable and updatable. If the driver and database being used do not support scrolling and/or updating of result sets, an application can populate a JdbcRowSet object with the data of a ResultSet object and then operate on the JdbcRowSet object as if it were the ResultSet object.
