Hi folks, I am trying to receive byte array data from a machine. It sends out 3 different types of data structure each with different number of fields which consist of mostly int and a few floats, and byte sizes, the first being 320 bytes, 420 for the second type and 560 for the third. When the sending program is launched, it fires all 3 types of data simultaneouly with an interval of 1 sec. Example:

Sending order: Pack1 - 320 bytes 1 sec later Pack2 - 420 bytes 1 sec later Pack3 - 560 bytes 1 sec later Pack1 - 320 bytes ... .. .

How do I check the incoming byte size before passing it to:

byte[] handsize = new byte[bytesize];

as the data I receive are all out of order, for instance using the following the read all int:

System.out.println("Reading data in int format:" + " " + datainput.readInt());

I get many different sets of values whenever I run my prog although with some valid field data but they are all over the place.

I am not too sure how exactly should I do it but I tried the following and apparently my data fields are not receiving in correct sequence:

BufferedInputStream bais = new 

 BufferedInputStream(requestSocket.getInputStream());

 DataInputStream datainput = new DataInputStream(bais);

 byte[] handsize = new byte[560]; 

 datainput.readFully(handsize);


 int n = 0;

 int intByte[] = new int[140];

 for (int i = 0; i < 140 ; i++) { 

 System.out.println("Reading data in int format:" + " " + datainput.readInt());

 intByte[n] = datainput.readInt();
   n = n + 1;
     System.out.println("The value in array is:" + intByte[0]);
       System.out.println("The value in array is:" + intByte[1]);
         System.out.println("The value in array is:" + intByte[2]);
           System.out.println("The value in array is:" + intByte[3]);

Also from the above code, the order of the values printed out with

System.out.println("Reading data in int format:" + " " + datainput.readInt());

and

System.out.println("The value in array is:" + intByte[0]);
 System.out.println("The value in array is:" + intByte[1]);

are different.

Any help will be appreciated. Thanks
