I read a tutorial 'Read file in String with BufferedInputStream', and I got a code from here:
The question is this line:
// byte array to store input
byte[] contents = new byte[1024];
So, how can I ensure it is 1024 byte? If I have a data with 1025 byte, and my code will break. So, how can I make it more generic? Thanks.
In the code that you are referring to the array is filled by calling
byte[] contents = new byte[1024];
int bytesRead=0;
bytesRead = bin.read(contents));
bin.read will see the size of contents and read at most 1024 bytes from the stream.
No,It won't break.
Magic is here
while ((bytesRead = bin.read(contents)) != -1) {
bin.read(contents)) It will read the next set of bytes from the file.
Question asked by me : How the buffer byte array is continuously filling while streaming?
