Although I can create and store queries using the Arango client, I can't find a way to create and retrieve them using the Arango java driver. The only place I can see a QueryEntity returned is when asking for long running queries.
In the same way I create Collections and graphs programmatically using the java api, I also want to create a few queries for debugging. I can't find a way to do this using the java api.

I need to create a local database for query purposes. I wish to build and populate a database with data from a number of text files, do the queries needed, and then destroy the database since it is no longer needed.
I am currently programing it in VB.net but would eventually want to port into a java or like language so other platforms can be used.
I prefer something that does not require the user to download something else to make this work. A person I asked did suggest SQLite but I am not sure how to load it internally.
Java SDK includes Derby Database - see the link.
That can be used without further download (only Java needs to be there of cause)

For example,there is an app called System Analyst that shows me how much data has been downloaded in the current session.I'd like to use this data in another app,which I want to write in C or Java.
Is this a bad idea?If so why?
Usually it's better to go to the source of the information instead of trusting some other application. In the case of data received and sent, you can get them directly from the kernel by reading /proc/net/dev.

Hi every one I'm doing a small program to listen and notify using POSTGRESQL and JAVA. I just want to get notification message, to be stored in a file or MySQL database. Can any one guide me where I can find documentation or sample code for this.
Assuming that you are using JDBC, you can use the PostgreSQL extensions of the standard. In particular, you need the org.postgresql.PGNotification class to receive notifications that you have to explicitly poll for. See the JDBC documentation here. There is a fully worked-out example in the docs.

Let me know is it possible to move the data in an object to the csv file using java code and if possible Please give a small description on how does it possible.Thankyou in advance...
You can do it in Java using supercsv library. Check this link, you can directly construct beans out of the csv file.

Though you can also achieve the same without using any library.

I was wondering if anyone knows how to store series of data in an android app, and also how to call those data back (like a bible app or Hymnal).
Is it XML or a form of SQL?
Thanks.
If you are going to store/retrieve a small data (some variables) you can use sharedPrefrences and here is an example,but if you are going to store/retrieve big data you can use database SQLiteOpenHelper example.
