hi all,
i have question about names of origin of a flight and the destination of a flight , they are not the real world names , is that what we are going to use
in our search string when searching in the criteriaFind( String st )
The following is the description of one of the record that i have
in my database
Name = Flight number value = BA002
Name = Origin airport value = BA0
Name = Destination airport value = BA0
Name = Carrier value = BA002SFOLHRBeethAir
Name = Price value = BA002S
Name = Day value = BA0
Name = Time value = BA002
Name = Duration value = BA002SF
Name = Available seats value = BA00
As you see value of origin airport and destination airport is same.Please through some light on it.
thanks
kanwal

Following is the code that came up with the values shown above
Data data = new Data("./suncertify/db/db.db");
for(int i=0; i<=data.getRecordCount(); i++)<br /> {<br /> if (i>=1)
{
DataInfo dataInfo=data.getRecord(i);
FieldInfo [] fInfo = dataInfo.getFields();
System.out.println("The String version of Data item is :"+ dataInfo.toString());
}
}

please reply
thanks

Yeah
the name of the origin and dest airport are
not user friendly names
Actually they are three digit codes which are used
world wide like JFK, LGA, MCI etc etc
We can map these three char codes to actual names
but I don't suggest that of SCJD appliation
I think we should follow the requirement documentation.

thanks for reply singh
since the name of the origin of the flight and the destination of the flight are same , you that is what we will be searching for in our criteriaFind(String ) to get the required information

Hey I think U must be doing something wrong
I tried the similar code in my application and got
something like this:
suncertify.db.DataInfo@62cb55recordNumber = 1
Fields:Name = Flight number value = SA001
Name = Origin airport value = SFO
Name = Destination airport value = DEN
Name = Carrier value = SpeedyAir
Name = Price value = 400
Name = Day value = Sun
Name = Time value = 13:40
Name = Duration value = 20m
I don't know why U are getting BAO and similar stuff

Hey
On the second thought, I think there is something wrong
with your data convertor, test it or try reverse conversion
I can smell that U have some problem with ur data convert.

Hey come on yaar
don't tell me that U were trying ur stunts on a text file
Any way, regarding convertor.
it is fairly straightforward.
U need to parse the text file and use the
Data class methods to write records into
binary file.
For parsing I used StreamTokenizer, U can also use
string tokenizer or any other approach

Actually I have given a text file and as a part of assignment
I have to write a converter to convert the text file
into binary file

my problem was that i was working with crupted db.db file. Any way my assignement is shipped with db.db in a binary format , so i do not have to write any conversion tool for this
