If the length of array
value is less than the number of bytes remaining to be read from the stream, the array will be filled. A subsequent call reads the next increment, and so on.
If the number of bytes remaining in the stream is less than the length of array
value, the bytes will be read into the array. The return value of the total number of bytes read will be less than the length of the array, indicating that there are no more bytes left to be read from the stream. The next read of the stream returns -1.
length is negative, or
length is greater than the length of the array
value, then an
IndexOutOfBoundsException is thrown. No bytes will be read from the stream for this exception case.
the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached
