getBytes() urgent ????????

[Gurpreet Saini]

Hi reader,
I had fixed my deprecated String class constructor by using this following signature
new String(byte[], int, int);
But I am having a problem in using getBytes() method . Whenever, I book the seats on particular filght that record is skipped for ever. I do not understand why this happens ?. Please comply as soonas possible.
Thank you,
:roll:

Could you post some code that demonstrates the problem?

Hi Gurpreet,
I don't think it has to do with the readRecord at all. It probably has to do with how you built your DataInfo that was passed into the modify method on Data. Be sure that LIVE_RECORD is set on the DataInfo or the record will be skipped.
Hope this helps,

Hi there,
This is the code which skips the record on which modification of avalable seats is done:

int size, space, toCopy;
byte [] buffer = new byte[recordLen];
buffer[0] = LIVE_RECORD;
int offset = 1;
for (int i = 0; i < description.length; i++)
{
space = description[i].getLength();
// size = newData[i].length();
// toCopy = (size <= space) ? size : space;
newData[i].getBytes();
offset += space;
}
db.write(buffer);
}

Hi Gurpreet,
You're not copying the bytes into buffer.
You should have something like:

            System.arraycopy(newData[i].getBytes(), 0, buffer, offset, toCopy);

Also, you should uncomment the "size = ..." and "toCopy = ..." lines.
Hope this helps,

Hi Morris,
I thank you, for your help. Now, it is functioning properly. Morris did your policy granted "all permissions" or it supplied certain parameters ?. Second, If I implement lock / unlock in Data class then does it mean that I am modifying Data class. This I am asking because my DataAccess class is extending Data class. Or shall I implement my lock / unlock in DataAccess class ?.

Hi Gurpreet,

Yes.

Second, If I implement lock / unlock in Data class then does it mean that I am modifying Data class. This I am asking because my DataAccess class is extending Data class. Or shall I implement my lock / unlock in DataAccess class ?.

I would say no, but it would probably be better to implement them in the child class from a pure design point of view, otherwise why subclass Data in the first place?
Hope this helps,
