java send file using sockets

Question

I am trying to send a file from one computer to another using Java. I have written the code below, it works fine if both sender and receiver are started in the same computer

Answer 1

Remember that in.read(buffer) not necessarily fills up the whole buffer with new data. Therefore you should make sure you don't write the whole buffer. Change

while((count=in.read(buffer)) >0){
    fos.write(buffer);
}

to

while((count=in.read(buffer)) >0){
    fos.write(buffer, 0, count);
}
