Dynamic Array and Adding Arrays

Correction:
                     byte[] total = null;
should be:
                     byte[] total = new byte[0];

And:
total      // the growing array
extend   // the place holder while total grows
have     // what is contained in extend
res        // what is read
got        // how much is read.

;JOOP!

for(i = 0; i < have;  ++i)
         {
              total[i] = extend[i];
         }


it will not be slow for processing? Sometimes it can receive 100MB data...

If you have any other suggestion for receiving huge data (this is part of server app's code) please advice..

Thanks

And what should be defination of in? It says cannot find symbol... I defined in as a DataInputStream...

A BufferedInputStream should do the job

Altohught I prefer your above solution to read data in an array... But please tell me how to read in BufferedInputStream and how to access data from that?

And also if you can please tell me how to use your above code... Just tell me what should be defination of in?

Thanks alot

And what is the defination of res in your above code?

in is your input stream
res is a byte[]

Thanks alot object... I tested your code...

I wrote:
int i =0;
ByteArrayOutputStream outx = new ByteArrayOutputStream();
byte[] res = new byte[1024];
while ((i = in.read(res)) != -1) {
outx.write(res, 0, i)
}
System.out.println("HERE");
byte[] received = outx.toByteArray();

But it never prints out HERE!

Why?

sounds like u don't get an eof.
make sure sender closes the stream once they have sent all the data

How to close stream??? It is VB6 app.

>>
But it never prints out HERE!

Why?

Probably because it's not closed by the other side

probably something like  out.Close

Anyone could provide an example of receiving data from socket in BufferedStreamReader?

Thanks alot

Sorry BufferedInputStream

As usual, after a night I wake up and the question completely has gone out of hand.
CSecurity, you should have asked a new question, because the original question has been answered.

;JOOP!

the code I posted earlier will would not need to be changed, just change the type of input stream as I mentioned

InputStream in = new BufferedInputStream(client.getInputStream(), 65535);
int i =0;
ByteArrayOutputStream outx = new ByteArrayOutputStream();
byte[] res = new byte[1024];
while ((i = in.read(res)) != -1) {
outx.write(res, 0, i)
}
System.out.println("HERE");
byte[] received = outx.toByteArray();

We're now going backwards - 'HERE' (probably) won't be printed

> We're now going backwards - 'HERE' (probably) won't be printed

ROTFL, in that case the code u posted would have the same problem.
Suggest you worry about your own suggestions which btw seems to be the one going backwards, can't think why you'd be suggesting reading one byte at a time :D

My suggestions need to be combined with those i made in CSecurity's other current one. When they are, it will become clear why i'm suggesting reading one byte at a time

InputStream in = new BufferedInputStream(client.getInputStream(), 65535);
int i =0;
ByteArrayOutputStream outx = new ByteArrayOutputStream();
byte[] res = new byte[1024];
while ((i = in.read(res)) != -1) {
outx.write(res, 0, i)
}
System.out.println("HERE");
byte[] received = outx.toByteArray();


This code works... but problem still exists... It's slow! So slow!


Even I changed part of outx.write to write in a file directly instead of using memory and using arrays...

But still SO SO SO Slow! Why?

Please advice... you experts use which code for retriving HUGE data in Java via sockets?

Thanks alot

No expert, without access to Sun's closed source, can answer that question properly, quite apart from needing to know more details on your setup

What you want to know?

I wrote all of my code above...

I use InputStream for reading data from socket...

Then I used objects code to receive data then I used buffered stream to write in file...

What you want to know more?

But this code never worked fast... So SO SO SO slow!

Thanks alot

Is it possible that because I use NetBeans it becomes slow?

Yes it is, especially if you're in debug mode

No I'm not at debug mode...

I just created a jar file and runned jar file which made in Netbeans in other PC ...But same problem...

You mean using Netbeans API and NEtbeans files makes it slow?

How about DatagramPacket?

DatagramPacket is faster?

> Yes it is, especially if you're in debug mode

why??

Dont' worry about debug mode... I'm not using debug mode...

Now... Do you think DatagramPacket is better?

java i/o is going to be slower than native i/o, how you run it has nothing to do with it.

datagram is no good to, as you could lose packets.
