Transfer file get percentage complete

Going to create a program to transfer files between two different computers via sockets.
And the only problem I'm currently facing is trying to find a way to get the percentage complete.

One solution I figured was splitting parts and as I send them, update the percentage.
(First send information object with full size of file, name and so forth. Then as I send parts of the file it updates how much has been downloaded). Though I hope that there is a simpler method to do this, like getting access to the buffer or something when it is being filled..

Anyone have a example, or a link to an example which can help me out, I would appreciate it a lot.

All you need to do is use the write(byte[],int,int) method of OutputStream to send the file in chunks. Then to get the percentage you divide the number of chunks sent by the total number of chunks and multiply by 100. Good luck!

Sorry, what is simpler then sending the size then the data? Given the total size to receive, % is amount received/total size * 100

Sure, but I didn't know you could get the information about how much has been received. Thought when using TCP it will wait and buffer up all of the packets untill its done before it will report/execute next code.

How are you receiving the data? I assumed you were reading it. The read method returns how much was read.
I don't know how to know how many bytes are on your computer and not ready to be read buried within the TCP etc.

Well, I am reading it from an inputstream attached to the socket. If its just to use another thread or something to check how much has been read, then it shouldnt be a problem (thinking thats how its done).
