public int read(ByteBuffer dst) throws IOException
public long transfer(FileChannel dst, long position, long count) throws IOException
Warning: Many implementations cannot write beyond the length of the file. If the position exceeds the channel's size, some implementations may throw an IOException.
dst- the target FileChannel to transfer data into.
position- The position within the file at which the transfer is to begin; must be non-negative. Must be less than or equal to the size of the file
count- The maximum number of bytes to be transferred; must be non-negative
